to invoke a OS process by Java is a part-of Java and its VM not GWT!

so ensure JDK runtimes are on the classpath (as Yingwei said, uncheck
app engine) and remember, GAE does not support it

  Hello, all.
  Who knows how to execute native code in server-side?
  There is  no Runtime class in gwt.
  I either can not use system.load(lib) to recall the outside dll due to
  security control.
  What can I do to solve this problem?
  Thank you.

Re: GWT security

its a way it works, like Greg said - a dumb client should not worry,
or better said not be too serious about security, everything what
happens on the client is INSECURE, so the only security concern it
should think about is to make the security look good to its user.

the real security should always reside on the backend, client shall
NEVER get a data from the server for unauthorized user so that client
can make decisions on its own - either to display the data or not.

 The correct syntax for the Image tag that reference an image resource is :

 Yes, that might be a problem in some case. You should be able to override
 the value from css if you wish.
 In some case, you might want to let the css default width.

 In this case, you should use DataRessource instead of ImageRessource. To
 declare this from uiBinder, the correct syntax is :

 *ui:data* field=*myResource* src=on.png

 style

 *...@url myResourceUrl myResource;*


 .myPanel {
   background: *myResourceUrl*;
 }

 Here, the image will be referenced without forcing width/height.

 Hi,

 The right syntax is :

 Then, simply use :

If your use case is to delete images (irrespective of user) after two
months, then cron Or timer job on server (Check Quartz) is the good
way to go. Remember in this approach you wont have access to user

If you need User Session to decide whether to delete or not , then you
can use SessionListeners on Server side.
Google for SessionListeners to know more about its use cases.

For sending mails , use javax.mail as per @mike's reply.

Shaffer,

This approach is a little overhead in the maintainability of the code
(and
in the methods too, since every server call will make a extra call to
the
database).

GKotta

To avoid access to images that is in the database but the 2 month time
has
expired, you can make the check only in the methods that access the
images
in the database (if using hibernate this can be an interceptor).

This will introduce overhead, but only when images are needed.

If you cannot add a cron job at your server, create an speciall url that
requires a custom login/password and when that url is accessed you run
the
code that removes the images from the database. If possible use SSL in
this
part of the site and don't send the username/password in the query
string,
use the HTTP POST METHOD.

Then you can make a cron job in your computer (home or job) and create a
simple wget script that access that special url. This isn't the best
solution, but works when you don't have admin access to cron jobs in the
production server.

 menu item user maintenance on the application menu
 - if the user is able to view users, but not modify the fields, he
 will see the readonly form (just for view purposes)

 Everything just by annotate UI components with @Secured annotation

   Hi Greg,

   thanks for the answer. Who casers? Users cares!

   Let's imagine that you will modify all the data you are able to

   satisfied with that solution? Is that a common approach?

   Isn't that solution that you have client state consistent with your
   server implementation cool? Never wanted this kind of solution?
   Second thing: what about the session handling in your GWT

Hi Peter.

Not to be rude, but who cares?

Who cares if the user can see a screen that says Client Data, when
the user can't actually download any of that client data?

IOW, what's the point?  If your sever is properly secured, then users
who aren't allowed to see the client data won't be sent it, and users
who aren't allowed to modify the data will have their modification
requests denied.  If it isn't properly secured, then what AcrIS does
is pointless. no?

Yes, it's nice from the UI perspective to let the user know why they
can't see / change the data, but what in the world does that have to
do with security?

 Hi Stefan,

 of course, client side code could never be secured! AcrIS security
 fully depends also on securing the RPC services (on the server side,
 client side security is an complementary security - some kind of nice
 to have security)
 The goal is: if the user does not have rights to see some parts of the
 screens, it won't be displayed. If the user is not able to modify the
 data, he will see the readonly components.
 Anyway, server side security is also checking if the user is able to
 execute methods or if he is able to modify/see data he are reguesting.

 This coupled approached gives you completly secured solution for GWT
 applications.

Please advice, if you know of other better tree widget implementation.

If you can, switch to GWT 2.1 (maybe wait for Milestone 3, as some
things have changed since m2, such as ListView being renamed to
HasData) and use the CellTree:

  I have developed a large app using GWT-Ext, unfortunately the

  this I started evaluating how best to migrate away from GWT-Ext. This
  involved looking at the alternatives.

  My preferred option was to go for a pure GWT approach mainly because
  you no longer have to worry about working around problems in a wrapped
  JavaScript library - debugging these type of issues is not easy.
  Unfortunately the current pure GWT widgets just aren't good enough, so
  I have had to postpone any migration for the moment.

  Anyway to get back to the point I think that although the hybrid
  approach may be tempting in the short term, you will just be storing
  up long term support problems.

  The other option that I haven't fully explored yet is the GXT (Ext-
  GWT) approach, this is a pure GWT version of the Ext-JS library. The
  only issue I have with this approach is that it requires a commercial
  licence.

  As to your REST question, I make extensive use of this now from plain
  GWT and have no issues with it at all - in fact I've now started using
  it instead of GWT-RPC simply because it means that our other clients
  can then easily make use of the various services our server provides.

   Good reasons for using GWT include:
   - it's in java, so you get all the java tools (good IDEs, debugging,
   refactoring etc)
   - debugging in java in your target browser is worth quite a lot
   - it generates highly optimised javascript

   I believe that with SmartGWT you lose the code splitting ability for the
   javascript parts of their library. I don't know how viable the hybrid

   compatible with vanilla gwt widgets.

Unless you are specifically interested in comparing all your 42 compile

Re: How to build a rules-based form controller for a dyn. form in GWT

2010-08-12 Thread A.Augustini

Dear Sam:

 If you like the Tohu spec (but not the implementation choice) could
 you not use their data model for describing forms? That is probably
 the most time consuming and painful to undo mistakes bit.

Tohu follows a different tech approach (server-side rule eval 
actions exec) compared to my client-side intended approach ... what I
would need is exactly their rule engine-based approach on the client
side, i.e. in JavaScript.
Nevertheless, I guess that their concepts could be taken and ported to
a JS version, basically having 'RuleSets' of 'Rules' (expressed via JS
statements) as data structures plus 'ActionSets' with N 'Action'
objects, each containing one JS function. Finaly 1 big processing
routine (the JS-implemented rules engine) for managing the 'EventBus'
and triggering (a) conditions evaluation and (a) action execution.

 Not sure I full understand the two open aspects you describe. Being an
 old geek bore I'll have a go.
 a) config for a form (probably bad interpretation).
 If lifting Tohu's data model doesn't work (wrong or licence issues)
 then I quite like your idea of starting with HTML. You can then use
 HTML5 syntax to add what you need.
 form
    input type=text name=foo class=assertNotEmpty /
    input type=text name=bar data-hiddenIf=form.foo='blah' /
 /form

Well, your interpretation of the XML syntax extension of (X)HTML5 is
right.
My real problem actually is the JS-events-to-JS-function-call(s)
wirings, a mech basically consisting of (a) condition script pieces
and (b) parameterized action functions both intended to be
*reusable* for difference use cases within one HTML document. The
configuration I meant above should better be replaced by dynamic
widget refs  widget params passing into these reusable condition
eval functions as well as action functions during each use case --
or simply dyn. invocation would be the better term.
I guess my problem actually reduces to

 * How do I achieve the evaluation of JS expression statements during
runtime and enact dyn. invocations with case-specific params???

Maybe this makes it a little bit clearer:

 form
input type=checkbox name=cb1 value=Cats checked=checked /
 I like cats. br/
input type=checkbox name=cb2 value=Dogs / I like dogs. br/


input type=text name=text-field value={initialValue1}

   !-- shortcut form. (please, see also 2nd example below) --
   visibleIF ((cb1.checked=='true') AND (cb2.checked=='true')) /
visibleIF

/input
 /form

My problem is the dyn. eval. of these JS condition statements, and the
dyn. implicit call text-field.visible=true -- or better said:
set(text-field, visible, true).

A more detailed/rules-oriented form would be:

 ...
  input type=text name=text-field value={initialValue1}

!-- other form including visibility rule (here: guarded
actions) --
IF-THEN
  IF cond
((cb1.checked=='true') AND (cb2.checked=='true'))
  /cond
  /IF
  THEN
 do (text-field.visible='true') /do
 do (text-field.value= Oh, you like cats and dogs) /do
 do ... /do
  /THEN
/IF-THEN

  /input

Here multiple actions get executed dynamically whenever the guard
evaluates 'true'.

Basically this conditinal action(s) execution in *JS* issue (fixed
events set, conditional evals, fixed actions set) would cover all my
requirements for the form controllers.

Perhaps you have some further suggestions based on your experiences.

Again, thank you very much in advance.

Best regards,
  Alessandro

Re: How to build a rules-based form controller for a dyn. form in GWT

Alessandro,

Ignoring the UI for a moment and assuming HTML5 as your data model
(for model,
layout and behaviour) then I guess the non admin end user runtime
could be something like this:
1) We have the HTML5 from your previous example (is the admin user
going to type in the expressions?)
2) Use the DOM parser to generate the UI of your heavy GWT Widgets
MyTextBox etc, also creates MyRule objects in the tree of Widgets
(So pure GWT UI created from your HTML definition but not using that
in the browser)
3) The MyX Widgets connection themselves to the event bus.
4) Big decision is if you just have JavaScript objects that the
expressions work on or is the actual HTML Form objects... Pros and
Cons of both.
For sake of argument say you have the scripts act directly on the real
form.
5) Your MyTextBox widget has an onchange handler that fires events on
the event bus.
6) MyRule widget listens to events that may interest it.
7) MyRule may choose to execute the JS expressions (to see if they
should run) if they do then they fire another event to tell the
MyTextBox etc
that the underlying DOM may have changed. (Think you might need to
make your own wrapper to JS eval function. The JSONUtils probably does
the same thing
but safer to do your own). You might want to use a global variable
like form to make it clear what they are accessing.
8) MyTextBox checks to see if it is dirty. If it is it might re-draw
something.

This is pretty brute force and lots of events but is at least simple.
Not sure how you are going to drive the UI which would probably
influence how you code the rules.
If very noddy interface you might have XML for the rule like:
doMySet field=testField value=Oh, you like cats and dogs //
do
...
You could still have an Expert one that lets them do any crazy thing
that is possible in JS. At their own risk. I might be tempted by a
more functional approach where
you define properties so you don't have to have rules for making
things visible then hidden.

e.g. MyVisibleRule field=testField test=cb1.checked 
cb2.checked /
Is the usual tough question of when is a DSL better than a general
purpose language.

The semantic HTML movement will also probably be very helpful as
presumably you only want semantic markup in your form definition.

Cheers

Sam

 Dear Sam:

  If you like the Tohu spec (but not the implementation choice) could
  you not use their data model for describing forms? That is probably
  the most time consuming and painful to undo mistakes bit.

 Tohu follows a different tech approach (server-side rule eval 
 actions exec) compared to my client-side intended approach ... what I
 would need is exactly their rule engine-based approach on the client
 side, i.e. in JavaScript.
 Nevertheless, I guess that their concepts could be taken and ported to
 a JS version, basically having 'RuleSets' of 'Rules' (expressed via JS
 statements) as data structures plus 'ActionSets' with N 'Action'
 objects, each containing one JS function. Finaly 1 big processing
 routine (the JS-implemented rules engine) for managing the 'EventBus'
 and triggering (a) conditions evaluation and (a) action execution.

  Not sure I full understand the two open aspects you describe. Being an
  old geek bore I'll have a go.
  a) config for a form (probably bad interpretation).
  If lifting Tohu's data model doesn't work (wrong or licence issues)
  then I quite like your idea of starting with HTML. You can then use
  HTML5 syntax to add what you need.
  form
     input type=text name=foo class=assertNotEmpty /
     input type=text name=bar data-hiddenIf=form.foo='blah' /
  /form

 Well, your interpretation of the XML syntax extension of (X)HTML5 is
 right.
 My real problem actually is the JS-events-to-JS-function-call(s)
 wirings, a mech basically consisting of (a) condition script pieces
 and (b) parameterized action functions both intended to be
 *reusable* for difference use cases within one HTML document. The
 configuration I meant above should better be replaced by dynamic

 dyn. implicit call

Re: How to build a rules-based form controller for a dyn. form in GWT

Me again,

Thinking about it a bit more it would probably much better if the HTML
form that the JS
worked on was not the same as the one the user is filling in. So you
have a fancy
form generated by GWT and an underlying very simple one that the JS
works on.

Some advantage are:
1) The JS should never touch your real form (difficult to sandbox
though!) They could call alert or window.location... XSS fun...
2) If your MyTextBox stores its state in something like
http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/dom/client/TextAreaElement.html
to go to/from HTML.
So, as you describe, in preview/edit mode you would have a natural way
for Widgets to add themselves to the model.
3) The fancy form the user sees could be very different to the
abstract model form. And you could evolve this without breaking the
model.

Subversion Access with File Writing/Reading

2010-08-12 Thread day_trader

My web service, written in GWT (with GXT) needs an XML configuration
file. At the moment, the file is in my resources area. Therefore, by
calling a service on my server, it will grab the file, unmarshall it
with JAXB etc, etc, etc.

However, at some point, I will need to access subversion. This will
allow me to: Check one of many configuration files... edit it in my
application if need be and 'save' (i.e. marshall everything back into
xml and then commit into subversion).

I also need a way to create a 'blank file', in case a user wants to
'start fresh' and build their own configuration from scratch, thereby
using subversion once the XML file is created.

What would be the best way to do this, if it is deployed in Tomcat?
From what I understand.. there is something called 'Sandbox' in the
app engine? Is this the kind of thing I want?

Thank you kindly,

Malcolm.

   Normally you would use gwt sprites in css like this:

  But this will cause that GWT adds the width and height according to
  the image dimensions. This results in a list item with unwanted
  dimensions.
  Normally you can solve this with a div that wraps the div containing
  the image.
  However how to do this with a bullet list item?

 You don't want spriting (possibly compositing multiple images into a
 single file and using CSS hacks/tricks to only show the portion you
 want), that won't work with list-style-image which expects a uri.
 Instead, you should use a DataResource:

 @url bulletSimple bulletSimple;
 ul.bulletSimple li {
   list-style-image: bulletSimple;

 }

Re: Change font-size on window resize

2010-08-12 Thread Henrique Viecili

There are a couple options using CSS:

1. if your layout supports you can try the 'zoom' property, it's not a
standard but it should work in most browsers. (I would not recommend
it anyway)

2. specify all your font-size's using the 'em' unit, then you can
dynamically change the base font-size and all others should follow
according to their 'em' value. You can find lots of resources over
this subject, this one is a good start: http://www.w3.org/WAI/GL/css2em.htm

This is the code to dynamically change style properties:
DOM.setStyleAttribute(element, property, value);

to get the Body element you can use:
RootPanel.getBodyElement();

 is wrapping all other elements in my application. By using relative
 font sizes in the CSS for my encapsulated panels, I'm hoping to
 propagate any changes to the font size of the lower-level element to
 higher-level encapsulated panels.

 In fact, when I statically change the font-size of div{} in my
 external style sheet, all the text in my application is affected, so
 it seems to be possible. However, I would like to do this dynamically.
 Naively, I expected that I could simple change the font-size of the
 root element (RootLayoutPanel.get().getElement() in my case), but that
 does not have any effect on higher-level text fields. I'm a newbie
 when it comes to CSS, so maybe I'm not getting inheritance correctly.

 In a nutshell, is it possible to programmatically change the font-size
 style property for one element and thereby affect all child elements?

Re: Making GWT look good...

2010-08-12 Thread Uberto Barbini

We're developing a web 2.0 style app with gwt.
I cannot post url here (not yet) but the goal is something like
basecamp or twitter, nothing to do with desktop style widget (also
cool ones like vaadin).

Our experience so far:
1. UiBinder is much better than try to create our own widget by code.
2. it's still much harder to get good looking results with GWT than
with plain html with Jquery.
3. overall gwt is worth the pain 10 times if you add snappiness of
resulting application, debug, and code reuse.

about #2 there is absolutely no documentation on css and uibinder from
a designer point of view.
For example any half decent designer nowadays would use div and span
to create nice layout, while all gwt panels are still using nested
tables.

.gwt-TabBarItem - setting Max width

2010-08-12 Thread Bhavik

Hi,

I am trying to set a max width value on the Tab-Bar item but it seems
that the size of the item is always equivalent to the size of the text
entered for the barItem.
I am trying to implement a google chrome style tab panel structure
where if the number of tab increases the size of each tab is
readjusted.Is there any option to this.

.gwt-TabBarItem {
max-width: 30px;
margin-right: 3px;
margin-bottom: 2px;
padding: 1px 5px;
background-color: #C6CAB7;
color: white;
font-size: 10pt;
cursor: pointer;
}

Thanks,
Bhavik

String.matches() does not work with \p{ASCII}

2010-08-12 Thread Vlad

Hi,
I have a simple code that works correctly in development mode but
fails to run on production.
Basically, I need to check if the text entered by user contains only
ASCII characters. So, I do the following:

String s = getTextArea().getText();
if(s.matches(\\p{ASCII}*))
{
...
}
else
{
// Some non ASCII characters found
}

On the production it always comes to the else section. I've tried it
with IE, FireFox and Chrome. The results are the same.
Any suggestions of how to fix this?

GWT compiler breaks valid JS

2010-08-12 Thread consiliens

Simple code that changes the background to black and creates a square 
fails to work when compiled by the GWT compiler.  The code works in 
hosted mode and when the JavaScript is run manually.  In the latest 
version of Firefox the compiled code doesn't run.  If the innerHTML call 
is commented out the bgcolor still doesn't change.


Why doesn't this code work when compiled?

// GWT Java
final Document document = Document.get();
final BodyElement body = document.getBody();

body.setAttribute(bgcolor, black);

String html = div style=\ + z-index: 0; + position: absolute;
+ left: 0px; + top: 0px; + width: 100px; + height: 100px;
+ overflow: hidden;
+ background-color: rgb(255, 255, 255);\/div;

DivElement ele = document.createDivElement();
ele.setInnerHTML(html);
body.appendChild(ele);

// GWT JavaScript
document_0 = $doc;
body = document_0.body;
body.setAttribute('bgcolor', 'black');
ele = document_0.createElement('div');
ele.innerHTML = 'div style=z-index: 0;position: absolute;left: 
0px;top: 0px;width: 100px;height: 100px;overflow: 
hidden;background-color: rgb(255, 255, 255);\/div';

body.appendChild(ele);

// Custom JavaScript
document.body.setAttribute('bgcolor', 'black');
var ele = document.createElement('div');
ele.innerHTML = 'div style=z-index: 0;position: absolute;left: 0;top: 
0;width: 100px;height: 100px;overflow: hidden;background-color: rgb(255,

Detecting Network connection loss - com.google.gwt.user.client.rpc.InvocationException

2010-08-12 Thread nokostar

What is the best way of detecting a loss of network connectivity to
the server? I have a GWT app that saves state to the server through an
RPC. I would like to be able to detect when the connection to the
servers fails so I can take appropriate action. I disconnected my
network by removing the network cable on a client machine to see if I
can be able to catch the InvocationException in the AsyncCallback's
onFailure method with no luck at all.

public void onFailure(Throwable caught) {
GWT.log(RPC Failure,caught);
if (caught instanceof InvocationException){
//do something
}
}

Re: showing all the elements from SuggestOracle in suggestionBox

2010-08-12 Thread ctasada

Hi Aditya,

The problem is that you don't have direct access to the SuggestBox
popup.

If you want to see all the possible solutions you should extend the
SuggestOracle and implement your own requestSuggestions method (see
this link for some nice examples: http://development.lombardi.com/?p=39)

In this way yo can simply return all your list, even ignoring the
limit.

Regards,
Carlos.

GWT/Tomcat serialization issues during deployment

2010-08-12 Thread duey

I have a simple application setup. It is comprised of a single module
that has one responsibility. Its job is to test RPC in my
application. Here's what I have. First, on the client side, I have a
TestData object. This object implements java.io.Serializable. It has
one member variable, which has a public access modifier. On the
server side, it's very simple. I have an implementation of a
RemoteServiceServlet that has 2 methods. One that creates an instance
of TestData, the other that accepts an instance of TestData and simply
returns true.

I have 2 goals:
1. I am testing if the TestData can successfully travel from server-
side to client side.
2. I want to create a TestData object and send it to the server side.

I am deploying my application as a WAR file with Tomcat. Tomcat is
running with security enabled.

I can successfully accomplish my first goal. I get the object back
from the server and display its contents in a Label. When I attempt
the second goal I get the following exception:

2010-08-11 21:24:37 StandardContext[/trunorth]Exception while
dispatching incoming RPC call
java.security.AccessControlException: access denied

snip...

In terms of code, this is what I'm trying to do from the client side:
testService.sendTestData(new TestData(), sendTestDataCallback);

The communication with the server is fine. The ONLY problem I have is
when I try and create a custom object on the client side and send it
to the server. How can I get around this WITHOUT modifying Tomcat
permissions?

When I officially deploy this application I won't have access to
Tomcat's permissions so I need to make this work with the default
Tomcat security settings.

Please explain to me why a custom object can travel from server to
client with no issues, while the converse is not true.

Thanks in advance

Re: Scraping website with GWT

hmmm... you could use IFRAME to load the page, some JSNI to get the

do the thing.

but should be much easier if you use any server side language to do
that for you

as you probably know, regex is belongs to that cases not fully

check for click handlers that you are registering for that particular link
Ideally it should work fine...
meanwhile if you are losing that event handler after first click then and
then only this problem could be faced.
I never faced such kind of situation with the links

Re: String.matches() does not work with \p{ASCII}

and if you really want to check for ascii why dont u just check for
the ascii code? try java.lang.Character to check or write in JSNI
small for-each testing if decimal value of char is greater than 127 is
faster than a regex evaluation

synchronize asynchronous calls?

I don't know if the title makes sense but working with gwt for about 2
years, I often find myself in the position to mix both asynchronous and
synchronous (blocking) apis. It's easy to transform a synchronous call to
asynchronous, but the other way around is not immediately obvious to me,
especially in the context of the single-threaded browser environment.

Imagine I the following:

abstract class GetListT {
  abstract void execute(AsyncCallbackListT callback);
}

class GetContactList extends GetListContact {
  void execute(AsyncCallbackListContact callback) { /* implementation */
}
}

class GetAddressList extends GetListAddress {
  void execute(AsyncCallbackListAddress callback) { /* implementation */
}
}

class GetPhoneList extends GetListPhone {
  void execute(AsyncCallbackListPhone callback) { /* implementation */ }
}


now imagine I keep a list of GetList objects:
ListGetList commands = Arrays.asList(new GetContactList(), new
GetAddressList(), new GetPhoneList());

and I have an executor that executes these commands:

class Executor {
  List? extends GetList? commands;
  Executor(List? extends GetList? commands) {
this.commands = commands;
  }
  void execute() {
  // XXX:
  }
}

Now, for whatever reason, I need my execute() method to be a blocking call
(synchronous). It should terminate after all GetList calls are returned. How
can I achieve this?

Re: Images only show sometimes

My guess is that, sometimes the code gets run, and other times it
doesn't?

Can you show some code? Where are your images stored? You can also try
to upload it to GAE and see if the problem shows up there too. Maybe
it is just a localhost issue, although I doubt it.

Re: GWT security

Personally I would like to know proper name for it

I'd go for Consistent UI design.  Which, I admit, doesn't sound
nearly as sexy as improved security.  BUt that is what you're doing:
you're keeping the UI consistent with what the user is allowed to do.

Another way to put it is don't tease the users.  Don't let them
think they can edit data, when they can't.

Re: GWT security

I'm talking about displaying the screens and securing the
components.

The problem is that that is a meaningless statement, and to the extent
that it's not meaningless, it's pointless.

I suppose you could set up your code so that the JS to display a
screen isn't downloaded unless the user will be able to use that
screen, but why bother?  What is the win by doing that?

Speaking for myself, I'd MUCH rather have a screen show up, and tell
me I can't use it, then not be able to find the screen.

After all, if I find the Update Data screen, and it says you do not
have permission to use this, then I know I dont' need to look for it
anymore.

And, if the server has my security credentials wrong, I can call tech
support, tell them that, and have them fix it.

Calling tech support to tell them I can't find a screen at all is a
much different, much more aggravating, call.  For both me AND the tech
support person.

It's not security, it's just a tech support and UI nightmare.

Re: synchronize asynchronous calls?

 Don't you have to count the async returning and then do yet another

 So hook into the callback of all your commands and then when the last

Extending salk31's logic:
Put your execute() inside a loop, inside an IncrementalCommand. Your
execute() routine implements a mutex. The loop terminates per salk31's
observation. The execute() routine sets the mutex before the async call,
and clears it in OnResponseReceived(), OnError(). The loop checks that
mutex and immediately returns to the IncrementalCommand if set. In FF
3.6, I found it was too easy to overload the server (resulting in
response timeouts) w/o serializing the calls via a mutex. IOW, simply
allowing the brower's RPC queue to serialize (i.e. clear the execute()
queue as fast as possible) resulted in dropped calls.

I believe the above will work w/ Java RPC.

If there are many list elements, you might want a timer that controls a
loading... message.

Also, you might want to evaluate at the Dictionary class to see if
that's a better fit for the problem you're trying to solve.

Re: How to build a rules-based form controller for a dyn. form in GWT

2010-08-12 Thread A.Augustini

Hello Sam,
hello everybody:

@Sam: I've have to digest your thoughts in your 2 last postings a
little bit...

...but for the meanwhile: today I found Form Boss II, a commercial
form wizard tool with an interesting ui and -- more important --
some features that are close to mine. I think that these short intro
vids (= 4 mins each) could make more comprehensive what I'm trying to
achieve in GWT.

1. http://www.formboss.net/j-wiz
   [especially last third of the vid on surveys]

2. http://www.formboss.net/features
=vid2 Conditional Fields
also useful:
=vid1 Conditional Page Logic
   (modified php logic for page routing)

Here you'll see a multi-page form editor with in-place edit
functionality. The interesting part is Conditional Processing
subpanel where endusers can compose some script code via event 
operation, ... selection fields.
IMO the drawback still is that the enduser (form admin) still has to
provide hand-written script routines (see Extra Head Code panel in j-
wiz vid). [Maybe this could be taken a step further hiding this script
programming text area behind a more graphical ui -- comparable to the
Conditional Processing panel's one].

My key question in former posting thus becomes how to get these code
snippets running in the preview and production window (the objects 
wirings behind the scenes)???
Simple string copies into specific dom objects ... seem not to be
sufficient, seem they?

Kind regards,

Re: RequestCallback.onResponseReceived() always returning status code 0

2010-08-12 Thread Deepak Singh

Hi Philippe,
I also have to use proxy servlet in my GWT 2.1 project.
I have to make cross domain web services call and then the response xml has
to be sent to client code.
Can u pls suggest me how to modify this servlet to use for my project so
that i should be able to make cross domain web service call.

Thanks

Re: .gwt-TabBarItem - setting Max width

2010-08-12 Thread lineman78

You will need 3 things:

white-space: nowrap;
overflow: hidden;
max-width: 30px;

However, max-width is not fully supported in IE.  You can fix this in
a couple ways.

1) Use IE's CSS expression.
2) CssResource has some ways of getting values and acting on them, but
I believe this is only run once.
3) (Best Option) Whenever you add or remove a tab or the window is
resized recalculate whether the max-width is exceeded and set the
width to max-width, if not set it to auto.

I now noticed after deploying the GWT web app on the same domain like

calling the http://mydomain.com/u1/MySerlet. The 'MyServlet' is
getting request from Gwt.html and sending the response to GWT.html.Can

don't know whether the  request can be sent in the first place  if it
is against the SOP.

DockPanel.  How do I do it for a DockLayoutPanel?

Yes, I know, use uibinder.  That doesn't work when you're building
things grammatically, which is what I'm doing.

BTW, why don't the Showcase application use ANY *LayoutPanels?  I
thought they were supposed to be the preferred way to do things, no?

Hyperlink calls History.newItem on clicks, and History.newItem won't
fire a ValueChangeEvent if the target token is the same as the current
one (as, obviously, there would be no change in value).
You might want to use a Label (or maybe Anchor if you want it to
really work like a link, with the ability to open in a new window/tab,
copy link URL, etc.) with a ClickHandler in which you'd call
History.newItem *and* do what you want to do (or: call newItem(token,

your logic ValueChangeHandlers)

Re: compile report

2010-08-12 Thread Katharina Probst

You can just add this to your .gwt.xml:

set-property name=user.agent value=gecko1_8/ (or whatever user agent
you want).

You can also define a new module for separate compilation with
-compileReport. This is described
herehttp://code.google.com/webtoolkit/doc/latest/DevGuideOrganizingProjects.html#DevGuideModuleXml

Re: why we probably won't use GWT for a large UI project

2010-08-12 Thread lineman78

I can't help you with the TileGrid other than saying that you could
write something similar yourself with a little effort assuming you are
willing to overlook some of the niceties such as animation.  I have
used SmartGWT in the mast and would warn you to use extreme caution in
making the decision to use it.  It is not a GWT implementation, but a
GWT wrapper around an existing javascript library, so you don't get
all the advantages the GWT compiler gives you such as dead code
elimination and obfuscation.  The SmartClient JS library is modular,
so you can only load the modules you need, but as with any JS library
I would estimate most sites only use 10-20% of the code they download
and load.  Also, SmartClient and ExtJs both use a heavy layout engine,
which I have noticed causes major slowing in IE.

Unfortunately I cannot provide source code, but I can point you to
some resources and explain my approach.  Here is an article by some
GWT contributors on overlay types that should help you get started:

http://code.google.com/p/google-web-toolkit/wiki/OverlayTypes

I am using what they call the old way in that wiki.  To further
expedite things, which you might consider depending on the size of
your project; I have written an overlay type generator.  All I have to
do is write an interface for the overlay type and have the interface
extend JsonObject and it will generate the overlay type for me:

public interface JsonObject {
public void setJso(JavaScriptObject jso);
public JavaScriptObject getJso();
public void setJson(String json);
public String getJson();
}

public interface Shape extends JsonObject {
public void setArea(double area);
public double getArea();
}

GWT.create(Shape.class); produces:

public class ShapeJso implements Shape {
private JavaScriptObject jso;

...

public void setArea(double area)
{
setAreaImpl(jso, area);
}

private native void setAreaImpl(JavaScriptObject jso, double area)
/*-{
jso.area = area;
}-*/;

...
}

This is very simplified, but I have given you a few hints to some of
the tricks I had to use to get the generator method to work(see:
JsonObject).  Usually you would extend JavaScriptObject, but in order
to get the generator to work right I had to save it as an attribute.
You will want to consider if the generator is the right approach, I
think it took me a good 8-10 hours in the end to make a generator that
works for almost every case.  But you can get one that works for most
cases in 2-4 hours as long as you aren't doing anything too complex.

 Looks like we can use

  I commonly use REST and GWT in perfect harmony and it is very easy.
  Assuming you have the ability to output JSON instead of XML you can

 We have control over server APIs, and we have both JSON and XML. Would
 it be possible to share some sample code?

 . I personally
  don't know what TileGrid is,

 Seehttp://www.smartclient.com/smartgwt/showcase/#tiling_filter_sort
 d'n'd to sort. One should be able to change image captions, and have
 the customized data source trigger appropriate PUT requests to update
 the server items. I'd love to see this functionality from GWT.

  out of the box GWT isn't intended to
  be a widget library, but there are plenty of them out there.  Google
  is trying to add a lot more widget support which is evident by the
  data presentation widgets, but their original intent was to create a

Re: How to use gwt to synchronize outlook to get the appoitments of calendar

2010-08-12 Thread kgeri

Assuming a Java server backend the easiest way is using WebDAV and
connect to the Exchange server itself (unless the WebDAV connector is
disabled), you may get the calendar and mails from there.
See http://msdn.microsoft.com/en-us/library/aa143161(EXCHG.65).aspx
for some specs. But note that this approach will get quite messy,
since it lacks a proper Java library (you may have to write WebDAV
queries by hand). Also don't forget that you still need the user's
password for this to work.

It is not possible to use GWT for client-side interaction with Outlook
on the user's computer if you meant that.

Re: Making GWT look good...

 Our experience so far:
 1. UiBinder is much better than try to create our own widget by code.
 2. it's still much harder to get good looking results with GWT than
 with plain html with Jquery.
 3. overall gwt is worth the pain 10 times if you add snappiness of
 resulting application, debug, and code reuse.

 about #2 there is absolutely no documentation on css and uibinder from
 a designer point of view.
 For example any half decent designer nowadays would use div and span

Re: why we probably won't use GWT for a large UI project

Totally agree with lineman78 on the use of SmartGWT. We used SmartGWT to
build a prototype, only to find out that mixing Js library wrapper with
native GWT is bad. It's super easy in SmartGWT if you're building a simple
CRUD application, but anything beyond that which requires customized widgets
in GWT, then good luck, not to mention you can't use all the benefits of the
GWT compiler. We're currently using ExtGWT. It's nicer in that it's (mostly)
natively GWT, so you can always trace down the Java code, but still it's
layout is expensive, and widgets are not 100% compatible with the GWT widget
system. The event system is a mess to work with. We really need a good UI
library, preferrably supported by Google that's built on top of vanilla GWT
widgets.

 I can't help you with the TileGrid other than saying that you could
 write something similar yourself with a little effort assuming you are
 willing to overlook some of the niceties such as animation.  I have
 used SmartGWT in the mast and would warn you to use extreme caution in
 making the decision to use it.  It is not a GWT implementation, but a
 GWT wrapper around an existing javascript library, so you don't get
 all the advantages the GWT compiler gives you such as dead code
 elimination and obfuscation.  The SmartClient JS library is modular,
 so you can only load the modules you need, but as with any JS library
 I would estimate most sites only use 10-20% of the code they download
 and load.  Also, SmartClient and ExtJs both use a heavy layout engine,
 which I have noticed causes major slowing in IE.

 Unfortunately I cannot provide source code, but I can point you to
 some resources and explain my approach.  Here is an article by some
 GWT contributors on overlay types that should help you get started:

 http://code.google.com/p/google-web-toolkit/wiki/OverlayTypes

 I am using what they call the old way in that wiki.  To further
 expedite things, which you might consider depending on the size of
 your project; I have written an overlay type generator.  All I have to
 do is write an interface for the overlay type and have the interface
 extend JsonObject and it will generate the overlay type for me:

 public interface JsonObject {
public void setJso(JavaScriptObject jso);
public JavaScriptObject getJso();
public void setJson(String json);
public String getJson();
 }

 public interface Shape extends JsonObject {
public void setArea(double area);
public double getArea();
 }

 GWT.create(Shape.class); produces:

 public class ShapeJso implements Shape {
private JavaScriptObject jso;

...

public void setArea(double area)
{
setAreaImpl(jso, area);
}

private native void setAreaImpl(JavaScriptObject jso, double area)
/*-{
jso.area = area;
}-*/;

...
 }

 This is very simplified, but I have given you a few hints to some of
 the tricks I had to use to get the generator method to work(see:
 JsonObject).  Usually you would extend JavaScriptObject, but in order
 to get the generator to work right I had to save it as an attribute.
 You will want to consider if the generator is the right approach, I
 think it took me a good 8-10 hours in the end to make a generator that
 works for almost every case.  But you can get one that works for most
 cases in 2-4 hours as long as you aren't doing anything too complex.

Re: Building two war-files with Maven using different web.xml

  So hook into the callback of all your commands and then when the last

 Extending salk31's logic:
 Put your execute() inside a loop, inside an IncrementalCommand. Your
 execute() routine implements a mutex. The loop terminates per salk31's
 observation. The execute() routine sets the mutex before the async call,
 and clears it in OnResponseReceived(), OnError(). The loop checks that
 mutex and immediately returns to the IncrementalCommand if set. In FF
 3.6, I found it was too easy to overload the server (resulting in
 response timeouts) w/o serializing the calls via a mutex. IOW, simply
 allowing the brower's RPC queue to serialize (i.e. clear the execute()
 queue as fast as possible) resulted in dropped calls.

 I believe the above will work w/ Java RPC.

 If there are many list elements, you might want a timer that controls a
 loading... message.

 Also, you might want to evaluate at the Dictionary class to see if
 that's a better fit for the problem you're trying to solve.

Re: How do I set the border around elements in a DockLayoutPanel?

With a DockPanel I just create a CSS style, and apply it to the
Panel.  I did that with a DockLayoutPanel, and nothing seemed to
happen.  I searched the archives of this group for CSS and
DockLayoutPanel, and the concolusion I came to is that CSS doesn't
work with DLPs.  If that's not correct, I'd love to hear it, and see
an example of how to do it correctly.

Presumably the people writing GWT actually test the features they put
in it.  Given the paucity of example code, this belief has to remain
merely an assumption. :-(

Re: Caching issue in host mode?

2010-08-12 Thread markM

I believe the issue I was having is because I'm not using the -
noserver option as is explained in Google's FAQ.  However, the odd
thing is that I originally got my GWT Server Library / Spring
integration working briefly under the built in Jetty instance.  Not
sure how this was possible but it worked briefly as I was able to set
a breakpoint in the serverside extends GWTSpringController class
using a Spring DispatcherServlet and the breakpoint was hit.  Haven't
been able to get it to work since then (that is 404 error on the
nochache.js file since it stopped working) and the following FAQ as
well as the GWT Server Library FAQ both say that the only way to go is
to use the -noserver option and an external server such as Tomcat that
supports -server.xml files etc.

http://code.google.com/webtoolkit/doc/1.6/FAQ_DebuggingAndCompiling.html

This is a really big ease of use issue with respect to GWT.  Folks
are going to want to use facilities  such as the -server.xml stuff.
I'm going through the nightmare of using the -noserver option and its
a real pain.  I'm going to have to copy files manually to the tomcat
instance, I will now have to run two programs from within Eclipse (one
for client side debugging and another for server side debugging).  In
order to setup the second project I had to figure out how to manually
update my .project files and .settings folder files to bring new
natures and such into use.

If the GWT developers want this tool to gain mass usage well beyond
current usage these sorts of ease of use things need to be looked
into futher.  Can the built in instance be a Tomcat instance for
instance?  Or at least you could have the Eclipse plugin setup
the .project and .settings files so that its ready to run the
additional server side program for debugging serverside.  Galileo
comes with a Tomcat instance already so folks running Eclipse wouldn't
have to worry about installing Tomcat.

GWT is an awesome tool, I really get the whole facilitating 6 million
Java developers to do web development thing and not rebuilding the
wheel with respect to IDE's etc, and I have some nightmare JSF
experience under my belt to compare it with. GWT really blows away any
technology that requires the use of jsp's.  I'm trying to sell GWT
within my company but when folks that are new to the technology have
to spend a bunch of time mucking around with xml files just to get
basic debugging working it becomes a hard sell.  I'll wait it out but
I hope some of the issue above can be addressed within the next couple
of years.

By the way, here's what I needed to do to get the GWT Server Library
portion working (setting aside the -noserver issues).

1) Inherit your RPC class from GWTSpringController instead of
RemoteService
2) Add the following to web.xml
servlet
servlet-namegwtspringcontroller/servlet-name
servlet-class
org.springframework.web.servlet.DispatcherServlet
/servlet-class
load-on-startup1/load-on-startup
/servlet

servlet-mapping
servlet-namegwtspringcontroller/servlet-name
url-pattern/gwtserverlibtest2/*/url-pattern
/servlet-mapping

3) Create the file gwtspringcontroller-server.xml (note that the file
name begins with gwtspringcontroller which is the same name as the
servlet above) and place it in the same directory as web.xml.
4) put the following contents into the gwtspringcontroller-server.xml
file

?xml version=1.0 encoding=UTF-8?
!DOCTYPE beans PUBLIC -//SPRING//DTD BEAN//EN http://
www.springframework.org/dtd/spring-beans.dtd

beans
bean
class=org.springframework.web.servlet.handler.SimpleUrlHandlerMapping
property name=mappings
map
entry key=/greet 
value-ref=GreetingServiceImpl /
/map
/property
/bean

bean id=GreetingServiceImpl
class=com.pfizer.test.server.GreetingServiceImpl/
/beans

5) Additionally you'll need certain spring jar files as well as the
gwt server library jar file gwt-sl-1.1.jar.  I did find that I was
missing a lot of libraries but the errors that showed up in the
Eclipse console from Jetty were explicit as to the classes that were
missing so it was not too difficult to find those jar files.  Here is
a list of jar files in my project (not that you'll need all of them).

Re: GWT compiler breaks valid JS

2010-08-12 Thread André Moraes

Running the compiled code and the hand-made code the desired effect happens
(black background with white square).

I tested on Chrome 6 and FF 3.6.6

The only thing to notice is that i placed the code before the body tag, the
html that i used was:

html
  headtitleTeste/title/head
  body
  /body

  script type=text/javascript
$doc = document;
document_0 = $doc;
body = document_0.body;
body.setAttribute('bgcolor', 'black');
ele = document_0.createElement('div');
ele.innerHTML = 'div style=z-index: 0;position: absolute;left:
0px;top: 0px;width: 100px;height: 100px;overflow: hidden;background-color:
rgb(255, 255, 255);\/div';
body.appendChild(ele);
  /script
/html

If I place the code before the body the code don't work, but this is
expected since the browser execute the code when it reads the code, and
placing it before the body, the browser still don't know about the body tag.

Maybe this can help, since it work on hosted mode and only breaks on
compiled mode, this probably is a loading problem.

Hope it helps.

RE: WSDL

2010-08-12 Thread Armishev, Sergey

When you have pretty big WSDL file the problem is how automatically generate 
not only server side stubs but GWT RPC calls and data structures that GWT 
client can use. You don't want to program all those API manually. I used SUN 
jax rpc for that http://java.sun.com/webservices/jaxrpc/overview.html.  Example
WSDL
  complexType name=NmsObject
   sequence
 element name=ObjectType type=xsd:int minOccurs=1 maxOccurs=1/
 element name=Initialized type=xsd:boolean minOccurs=1 
maxOccurs=1/
   /sequence
  /complexType

jaxrpc compiler then generates the following code (see below). For GWT you need 
to change those generated classes (either manually or from script) 
1. make class serializable
public class NmsObject implements java.io.Serializable
2.Change structures that doesn't have support in GWT like bigint or Calendar 


// This class was generated by the JAXRPC SI, do not edit.
// Contents subject to change without notice.
// JAX-RPC Standard Implementation (1.1.3, build R1)
// Generated source version: 1.1.3

package com.yourcompany.client;


public class NmsObject {
protected int objectType;
protected boolean initialized;

public NmsObject() {
}

public NmsObject(int objectType, boolean initialized) {
this.objectType = objectType;
this.initialized = initialized;
}

public int getObjectType() {
return objectType;
}

public void setObjectType(int objectType) {
this.objectType = objectType;
}

public boolean isInitialized() {
return initialized;
}

public void setInitialized(boolean initialized) {
this.initialized = initialized;
}
}

Re: GWT compiler breaks valid JS

2010-08-12 Thread consiliens

I'm testing on Firefox 3.6.8 and can consistently reproduce the issue. 
Here's a hosted version of the Java code compiled with the pretty output 
style.

http://69.164.194.47/gwt/Isotile.html

The .java file is here.
http://69.164.194.47/gwt/Isotile.java

If I comment out body.appendChild then the bgcolor of body is properly set.

Is this an issue with GWT?  Is there a better way to write the Java code?

Thanks for your help.

Running the compiled code and the hand-made code the desired effect
happens (black background with white square).

I tested on Chrome 6 and FF 3.6.6

The only thing to notice is that i placed the code before the body tag,
the html that i used was:

html
headtitleTeste/title/head
body
/body
script type=text/javascript
 $doc = document;
 document_0 = $doc;
 body = document_0.body;
 body.setAttribute('bgcolor', 'black');
 ele = document_0.createElement('div');
 ele.innerHTML = 'div style=z-index: 0;position: absolute;left:
0px;top: 0px;width: 100px;height: 100px;overflow:
hidden;background-color: rgb(255, 255, 255);\/div';
 body.appendChild(ele);
/script
/html

If I place the code before the body the code don't work, but this is
expected since the browser execute the code when it reads the code, and
placing it before the body, the browser still don't know about the body tag.

Maybe this can help, since it work on hosted mode and only breaks on
compiled mode, this probably is a loading problem.

Hope it helps.

Re: synchronize asynchronous calls?

After some thought, I don't think putting it in IncrementalCommand and
execute with DeferredCommand help much here. Jeff, If I understand you
correctly, my execute method will look like this:

class Executor {
  // declaration of list of commands
  void execute() {
DeferredCommand.addCommand(new IncrementalCommand() {
  boolean executing;
  int currentIdx;

  public boolean execute() {
if (executing) return true;  // executor will keep looping
// it's my turn now
executing = true;
AsyncCommand cmd = commands.get(currentIdx);
cmd.execute(new AsyncCallback() {
  public void onFailure(Throwable e) { onSuccess(null); }
  public void onSuccess(Object o) {
executing = false;
++currentIdx;
  }
  }
  // return point
  }
}

The above method is actually still non-blocking. There's no guarantee that
my incremental command will finish executing before I reach //return point.
Did I miss anything?

 Extending salk31's logic:
 Put your execute() inside a loop, inside an IncrementalCommand. Your
 execute() routine implements a mutex. The loop terminates per salk31's
 observation. The execute() routine sets the mutex before the async call,
 and clears it in OnResponseReceived(), OnError(). The loop checks that
 mutex and immediately returns to the IncrementalCommand if set. In FF
 3.6, I found it was too easy to overload the server (resulting in
 response timeouts) w/o serializing the calls via a mutex. IOW, simply
 allowing the brower's RPC queue to serialize (i.e. clear the execute()
 queue as fast as possible) resulted in dropped calls.

 I believe the above will work w/ Java RPC.

 If there are many list elements, you might want a timer that controls a
 loading... message.

 Also, you might want to evaluate at the Dictionary class to see if
 that's a better fit for the problem you're trying to solve.

Yes. There are two functions:
o function a()  which empties your commands list
o function b() which is the deferred command

The technique works. Give me a few minutes and I'll post a follow-up
message w/ some code.

 2. it's still much harder to get good looking results with GWT than
 with plain html with Jquery.
 3. overall gwt is worth the pain 10 times if you add snappiness of

 about #2 there is absolutely no documentation on css and uibinder from

 For example any half decent designer nowadays would use div and span
 to create nice layout, while all gwt panels are still using nested

Re: How to build a rules-based form controller for a dyn. form in GWT

I'm with you that it seems very low level. If your users know enough
to write that much JS then
they would probably be better off with proper developer tools!?

So as you say, same engine but with more complete wizards might be
better.

 My key question in former posting thus becomes how to get these code
 snippets running in the preview and production window (the objects 
 wirings behind the scenes)???
I'm afraid I don't really see the problem here.

 Simple string copies into specific dom objects ... seem not to be
 sufficient, seem they?
In their example you would probably have to do something like reload
the constructed page so
script tags would be processed and old event handlers replaced/
removed.
In the design I was talking about, because the HTML/DOM, is just the
data model/config
you would just have to tell your Widgets to refresh themselves.

If you like Form Boss then you might be better off keeping it simple
(like them) and just working
on a chunk of HTML. Is certainly the most flexible way of doing it.
Quite a few off the shelf
WYSIWYG JS editors that let you write custom editor panels. Not very
GWT though ;)

 IMO the drawback still is that the enduser (form admin) still has to

Re: RequestCallback.onResponseReceived() always returning status code 0

2010-08-12 Thread Philippe Laflamme

Hi Jaya,

It's really hard to say. I guess I would try testing things in pieces,
see if they work independently...

First, try making the request to your servlet without GWT. That is,
use your browser (or some other tool) to make the request your server
expects and then verify that your getting the response you expect.

Once you've verified that the server part of things is okay, you can
move on to looking at your GWT code. At this point I guess you could
try some other JS library (jQuery for example) see if you get
different behaviour as GWT.

Hope it helps,
Philippe

 I now noticed after deploying the GWT web app on the same domain 
 likehttp://mydomain/u2/Gwt.html, it is not getting the response after
 calling thehttp://mydomain.com/u1/MySerlet. The 'MyServlet' is
 getting request from Gwt.html and sending the response to GWT.html.Can
 you please suggest any thing i should look into.? I am trying all
 possible ways. Interestingly the request has been sent to servlet. I
 don't know whether the  request can be sent in the first place  if it
 is against the SOP.

   Had the same issue. In my case, it was due to making cross-site

   My server was at localhost:8080 and I was running in DevMode at
   localhost:. Making a request from : to :8080 is considered a
   cross-site request (which is not per the same-origin policy).

   The behaviour in Firefox was that it would return 0 as the status code

   I solved this issue by running a transparent proxy on : in
   DevMode. The proxy forwards everything to :8080. I provided the

Hi All,
I have deployed the GWT web app ( only client code. no server code is

POST. The servlet is getting the Request (xml string) from GWT client
app and responding with a xml string ( appeared in the servlet logs).
But the GWT client's  onResponseReceived () always return a status

here  the basic code i am using. no fancy of it.

                String eventParticipationReq=Count id=\1\/Count;

Re: synchronize asynchronous calls?

 After some thought, I don't think putting it in IncrementalCommand and

   void execute() {
 DeferredCommand.addCommand(new IncrementalCommand() {
   boolean executing;
   int currentIdx;

 The above method is actually still non-blocking. There's no guarantee
 that my incremental command will finish executing before I reach

Looking at your code a bit more closely (and while composing an
example), I see that you want something that requires a bit more structure.

You have the IncrementalCommand() correctly implemented. Forget my
previous answer.

Now that I really understand what you're asking (I think)...

I solve the problem using a state machine. Notice how the SM loops on
DICTIONARYREAD until the command queue is empty.

DeferredCommand.addCommand(new IncrementalCommand() {
  @Override
  public boolean execute() {
switch (startupState) {
  case INITIAL:
timer.scheduleRepeating(600);
startupState = StartupState.DICTIONARYREAD;
break;

  case DICTIONARYREAD:
if (dictionaryRequest.getDictionaryPages()) {
   break;
}

startupState = StartupState.FINAL;
break;

  case FINAL:  // Kevin's RETURN POINT?
timer.cancel();
return false; // command is complete
  }
return true;
});

public boolean getDictionaryPages() {
 while (dictionaryRequestList.size()  0) {
if (busy) {
  return true;
}
dictionaryRequestList.pop().execute(); // RPC and BUSY mutex
 }
 return false;
}

Re: GWT compiler breaks valid JS

2010-08-12 Thread André Moraes

Things get a little more weird.

In chrome i see a black window, without the white square.
The code loaded in chrome was:

  var body, document_0, ele;
  !!$stats  onModuleStart('com.google.gwt.query.client.css.CSS');
  !!$stats  onModuleStart('com.example.isotile.client.Isotile');
  document_0 = $doc;
  body = document_0.body;
  body.setAttribute('bgcolor', 'black');
  ele = $doc.createElement('div');
  body.appendChild(ele);

Looks like the compiler removed the code where you add the div inside the
div element created by $doc.createElement('div');

In firefox 3.6.6 the code isn't download, only the selection script is
loaded and the code with the logic isn't request by the browser. Maybe it is
a problem with your host page because it don't have the iframe (just a
guess).

Try to use the element.getStyle() to access the sytle properties of the
element instead of setting the HTML directly. for example:

DivElement ele = Document.get().createDivElement();
ele.getStyle().setProperty(background-color,white);
/// ... the other styles
body.appendChild(ele);

Check this link:
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/dom/client/Element.html#getStyle()

Hope it helps,

Re: why we probably won't use GWT for a large UI project

2010-08-12 Thread lineman78

Not to mention the licensing on GXT is not for commercial use.  My
suggestion is to try to piece together all the UI elements you need
from other libraries or write your own as they will be more efficient
and integrate with one another better.  Also, don't be lazy and pick a
UI library by it's LAF, wonders can be done with CSS if you are
willing to spend a little time.  Don't get me wrong, I think both
options are valid for UI libraries, but I often think their
shortcomings are overlooked due to the eye-candy appeal.  FYI, I have
experimented with both libraries and both applications were eventually
rewritten in pure GWT and the performance increase in IE was drastic
and memory usage eas more than halved.  Also, resource bundles are
your friend when it comes to efficiency, just watch out for the IE
implementation of ImageResource; it can bite you.
