our gwt produces every few seconds a strange exception:
java.lang.IllegalArgumentException: Something other than a Java object was 
returned from JSNI method

i googled around and find that this could be related to autoboxing (in this 
case probably boolean-Boolean: JS value of type boolean, expected 
java.lang.Object). The question is: is autoboxing allowed in client code? 
is this a limitation of gwt? i never read about such an limitation and most 
of google results about that are outdated.
Ok now i found this: 
http://googlewebtoolkit.blogspot.com/2008/08/gwt-15-now-available.html 
-Simplify your code with for-each loops, autoboxing, static imports, and 
enum types.

So what is the problem here or how to debug this?

thx in advance

Re: How to get @Prefix value from an Place.Tokenizer? or how to set via clientbundle constants?

i have one problem with this solution: testability 
since i generate those links in an activity i want test it without 
GwtTestCase. But using my AppPlaceHistoryMapper smells like the need for 
GWTTestCase?!

i think i will refactor my code and give the place a string constant 
(public or with getter) and use this as prefix - good idea?

Popup windows printing

2011-10-26 Thread Mike Dee

I have an app that creates reports, which are basically HTML.  The
reports need to be printed and that is what I'm trying to figure out.

I'm porting an older app - that is more of traditional web app.
Reports are displayed in a page - with a UI wrapped around them.  When
a user wants to print a report, he clicks a print link, which pops
up a window with a printer friendly version (no UI elements).  He can
then selects the browser's print command.  Works nicely.

I'm trying to figure out how to do that in GWT.  I can display a
report.  Printing doesn't work well, because it prints all the UI
stuff too.

I've looked into separate popup windows.  Most of the messages here
recommend against doing it.  Instead they suggest using a Dialog box.
I've tried it and created a Dialog with simply an HTMLPanel.  However,
selecting File-Print (in the browser) prints the entire page (the
entire window).

Any suggestions on a way to do this?

Re: How to get @Prefix value from an Place.Tokenizer? or how to set via clientbundle constants?

Oh yes I think you will need a GWTTestCase as the mapper is created with 
GWT.create(). I did not had that in mind because I have implemented 
PlaceHistoryMapper myself (nicer url scheme) so there is no need for 
GWT.create().

Re: Nested Editor creation question

2011-10-26 Thread opn

Thanks for your answers!

I found my mistake.

My 

initWidget(uiBinder.createAndBindUi(this));

came too late in the constructor, after

editorDriver = GWT.create(Driver.class);
editorDriver.initialize(requestFactory, userEditor);

The editor was not initialized at that point and so i got the error.
Stupid mistake. Now works without provided=true (I initialized the self 
provided editor earlier, so the error didnt occur then).

Re: Editor not flush values of subeditors

 Thomas, thanks for the fast responce. I will see if this is causing the 
 error.
  
 AddressWidget implements AddressView and Editor for AddressProxy, you say 
 that the AddressView must be extend Editor?


I'm saying that the type of the address field in type TerceroEditor does 
not implement Editor (or IsEditor), so the Editor framework does not treat 
it as an editor. You'll either have to change it to AddressWidget, or make 
AddressView extend Editor.

Now, one design question. 

 I love MVP, this pattern is very powerfull but, with Activities and Place 
 some thing are dificult.

 Activities are for when you need navigation, but if want each view has a 
 Presenter, I thought the following:
   
One interface Presenter for each View, where View delegate the logic 
 in the presenter implementation.
Now, presenter is not Activity. When I need navigation, I make a 
 Activity that inject the presenter and delegate in this the logic of View.

I want keep separate in the best forms the concepts of view and 
 presenter, but I want to know if inject the presenter in view is ok.
   The presenter have a method called onCreate(T) where T is a View. That 
 method is called when View is initialized after make UiBinder interface.
   In the onCreate(T) I inicialize the editor driver, etc.

   When I precise a Activity, in the start method I obtain the view, by 
 example, with AsyncProvider, how the View inject Presenter, the Activity 
 delegate logic to Presenter.

  I started think this for nested complex widget, for example, load 
 Employees associated with bank accounts, where the Widgets for list of 
 selection and creation bank account is a widget that delegate logic in a 
 presenter that is not Activity.
  But, i can use this widget alone in other view where is necesary one 
 Activity.

   All this is fine or I've gone crazy?


I'm not sure I understood what you're coming with. All I can say is that my 
activities are presenters, and in a few cases where a complex component 
is to be reused, I have a presenter and view for it that's not an activity. 
I also inject my views within my presenters in their constructors, and the 
presenters inject themselves into their view when needed (when the 
activity starts, in my case); this allows the views to have longer lifetime 
as the presenters, because I use short-lived presenters and singleton views.

Handling authorization exception from server to client

2011-10-26 Thread André Salvati

Hi,

I've been working with GWT 2.4 and trying to send an authorization
exception from server to client whitout success.

1) Server:

A - Raise ReportableException throught report() on my
ServiceLayerDecorator.

B – Send the following JSON to the client:

{S:[false],I:[{F:true,M:Não
autorizado,X:com.google.web.bindery.requestfactory.server.ReportableException}]}

2) Client:

AbstractRequestContext doesn't enter on processPayload() → if
(response.getGeneralFailure() != null) because it doesn't find key
“F” (but “F” is there, isn't??)


What is wrong?

Is it the right way to treat this kind of exception?

Thank you.

Why GWT ignore standard html tags ?

2011-10-26 Thread Gervais.b

Hi all,

I'm playing with GWT since some weeks and now I want to create a form
(not int Html sense); In this form I want to use the Html label tag
to set focus on the field referenced by the for attribute value.

1° label for=fldFirstNameg:InlineLabel text={msg.firstName} //
label
But that don't works because GWT ui:field don't set the Id to the
field.

2° So I have tried to give an id to my field but now GWT complaints
because we can use id with ui:field.

3° I have Googled a little and found a topic who use en expression to
retrieve the field id :
label for={fldFirstName.getElement.getId}g:InlineLabel
text={msg.firstName} //label
But the for attribute stay empty.

4° I have decided to tell you Why GWT ignore standard html tags ?
and force us to write many boilerplate code for simple things ?
I think that the GWT has made an impressive work but I don't
understand why in many cases we have to ignore Html best pratice

Re: future of gwt who use gwt

2011-10-26 Thread Nagin Kothari

Dart is yet very very young.. .I think it will take more than two years to
gain popularity and acceptance(if at all?), also all browser vendors (like
Microsoft) acceptance.
So why worry right now about Dart?
Any way new client side technologies keep coming every year. If at all Dart
gains popularity in future,I think  Google would provide tool to convert
your GWT (java) code to Dart.

 hi thomas,

 thanks for link to infoq article about dart - so... it seems my guess
 is possibly right :) - but it's long long way ahead.

 as to mentioned issue with hashmap - i find it feature rather than
 problem. and that case is even not java-javascript but ie specific
 implementation issue.
 and as to gwt - since this is gwt group - i liked very much the idea
 of cross-compilation and possibility of maintaining big client side
 application in java. although it was gwt where i came across it the
 first time. but than i was not sure about it should try to mimic
 common java libraries. maybe sticking only to java raw language but
 with browser specific libriries would be a better solution? libraries
 that vastly utilize something like JavaScriptObject class in current
 implementation? maybe the wrong business policy was to target with gwt
 at existing java developers rather than motivate existing javascript
 developers to learn java :)?
 but no tool is perfect - especially from its begining - and
 imporovements are natural (notice java collections).
 gwt is still young, and java at its age was imho less convincing
 technology. if it is not due any legal/licensing strategy than i would
 stick to java in gwt... if i were gooogle ;).

 as to mysql - nice to see it on app engine - but this fact does not
 undermine the possibility of willingness to became independent from
 oracle owned technology.
 since mysql community server is open source and GPL licensed, google
 is no way dependent on oracle in that case. situation with java is
 quite different, and as i remember some time ago microsoft tried to
 make its own java, what has been effectively stopped by sun's sue and
 trial, utlimately resulting in birth of c# :).

Re: future of gwt who use gwt

I think in the future GWT will compile to Dart for browsers that support 
Dart and compile to JS (using the dart compiler) for older browsers. 

Also it seems like that (typed) Dart syntax is very similar to Java so it 
should be possible to convert a GWT/Java project to Dart. It wouldn't 
be completely automatic (deferred binding could be a problem) but I think 
its doable.

So I think you won't have any downsides of using GWT now. GWT will be 
supported a long time as its used in a lot of internal google projects. If 
you do not choose GWT you have to use JavaScript directly. If Dart becomes 
successful you have the same problem: How to convert a JavaScript 
application to Dart?. Using GWT I think you have a pretty good chance that 
GWT will solve this problem for you...

Re: CellTable - how to load just one page?



On Wednesday, October 26, 2011 7:20:20 AM UTC+2, Magnus wrote:

 Hi,

 I have a large list, which I do not want to load all at once. I would like 
 to load and display just one page and let the user navigate to other pages.

 The problem I see with CellTable is that it needs the whole list at once 
 (setRowData). So I have to transfer all the data. Is it possible just to 
 load the data for one page, and load the next portion if the page changes?


Are you kidding me? Just 2 days ago you asked how to display the whole data 
you loaded because CellTable uses paging by default!

Either you have the whole data set and you can call setRowData(List), which 
is just a shorthand for setRowCount(list.size());setRowData(0,list);
Or you have only a portion of the data (generally the size of a page, but 
not necessarily) and you'll call setRowCount (either you know exactly how 
many items the whole dataset contains, and you can call setRowCount(int), 
or you're not sure and you'll call setRowCount(int,boolean) passing 'false' 
as the second argument; if you really don't know, you can pass any big 
value as the first argument, and then adjust it later when you've reached 
the end of the dataset, ofr instance) and setRowData(int,List).

Other questions:
 How can I add a simple navigation buttons (page next, last) to a CellTable?


SimplePager ?

Finally, assume that the CellTable resides within a panel with a given 
 size. Is it possible to set the page size so that there are no scroll bars, 
 i. e. fill the panel with cell rows without exceeding the available space?


Only if you know in advance the height of a rendered row. You could also, I 
guess, reduce the page-size once loaded if you detect that scrollbars are 
necessary, until they're no longer needed (i.e. load a bit too many and 
then only show what fits in the display area).

Activities and Places, how to deal with nested views ?

2011-10-26 Thread Gervais.b

Dear GWT profesionnals,

I try to create an little app who allow users to make search. The main
screen contains some inputs and a TabLayoutPanel who contains two set
of inputs.
The main screen is created with UiBinder and the two containeds into
the tabs are also described with UiBinder. I have one activity who
manage the screen and perform the search.

But now I have to add another search button into the first tab. This
search button let the user do a search and complete the inputs. The
first solution is to add another callback method to the atcivity
doNestedSearchAndFillSubset() but this nestedSearch can prompt the
user with an popup panel to select one line from the result set...

Is it a way to manage the subSearch view and action with another
activity who is nested into the main screen activity ?

Thanks

F is present in I, meaning one particular invocation (service method

Anyone has any idea of what's the problem? I verified that the maven plugin
in the pom is of the same version of GWT (2.4.0). The SDK configured for the
project is also 2.4.0, actually is the only one installed.

I noted that Gin is indirectly importing GWT 2.2.0.. I wonder if this might
be the issue, and how to get it fixed...

The funny thing is that eclipse itself can find the sources for the method
which is supposedly missing, when I navigate to it using the stack trace
above.

Thank you for any help,

Re: Why GWT ignore standard html tags ?

 Hi all, 

 I'm playing with GWT since some weeks and now I want to create a form 
 (not int Html sense); In this form I want to use the Html label tag 
 to set focus on the field referenced by the for attribute value. 

 1° label for=fldFirstNameg:InlineLabel text={msg.firstName} // 
 label 
 But that don't works because GWT ui:field don't set the Id to the 
 field.


Yes, and there's a good reason for this (performance IIRC, and also the GWT 
team wanted to try other approaches than getElementById to retrieve the 
elements).
 

 2° So I have tried to give an id to my field but now GWT complaints 
 because we can use id with ui:field. 

 3° I have Googled a little and found a topic who use en expression to 
 retrieve the field id : 
 label for={fldFirstName.getElement.getId}g:InlineLabel 
 text={msg.firstName} //label 
 But the for attribute stay empty.


Yes, because as you said, ui:field doesn't set an ID on the element 
(actually, it does set one, but removes it right after use).
 

 4° I have decided to tell you Why GWT ignore standard html tags ? 
 and force us to write many boilerplate code for simple things ?


There are features that, if not done correctly, would cause a lot of bugs 
being reported, and would effectively move resources (human resources I 
mean) on fixing those rather than improving the toolkit.
There are ways to do what you want without too much 
boilerplate: 
https://docs.google.com/Doc?docid=0AQcd-Zsy2T-YZG1mZG5jNl84Z3NkMmJuZHo
And there are ways to do it without without writing any code: 
labelui:text from={msg.firstName} / g:TextBox 
ui:field=fldFirstName //label Just Works™, because the textbox is 
within the label, so there's no need for a for= attribute.
 

 I think that the GWT has made an impressive work but I don't 
 understand why in many cases we have to ignore Html best pratice


You don't have to.

Yes, with the added benefit that you could test whether you call the 
PlaceHistoryMapper with the appropriate argument, not whether the returned 
value from the place-to-string conversion is the one you expect (which will 
change when you change your PlaceTokenizer, but you're not testing your 
PlaceTokenizer here, you're testing your activity, and if the test changes 
when the implementation of another class changes –without breaking the 
contract: turn a place into a string–, it's no longer a *unit* test; and it 
also means you'd have to change all your tests when you decide to change 
what your PlaceTokenizer generates/parses).
With a mock, the exact output wouldn't matter, the input would however: 
does my activity calls the mapper with the appropriate argument?
 

 but now i am happy with my getPrefix() in place-class. With this i don't 
 need a dependency to historymapper in my activity. (it don't feels right to

Well, the goal of PlaceHistoryMapper *is* to get a string out of a place 
(and the reverse). Whether it's used by the PlaceHistoryHandler or your 
code the builds link doesn't really matter.

problems with loading stuff/bootstrapping onModuleLoad triggered by an event

the scenario is as follows (i use gin):
- onModuleLoad instantiates a ApplicationManager and runs start() on it.
- ApplicationManager sets up all activitymanagers and the layout, gives 
every manager some display area, sets up history handler and start 
history (historyHandler.handleCurrentHistory();)

all is running fine but i want the application manager to defer the loading 
until an event (data-loaded-event). so i make the manager listen to it and 
all the setup-stuff is done in a new method continueStart(); called on 
this event. the former start() (called in onModuleLoad) just displays a 
loading widget.
but now no activity is started. i debugged into the code. it seems that 
with this deferred loading the ActivityManagers don't hear the 
PlaceChangeEvent fired by historyHandler.handleCurrentHistory(); (The 
Eventbus emitting this event is the same the ActivityManager registered on)

So what's going on here?

my only explanation at the moment is, that this could be related to the 
fact that all the application setup stuff happens after onModuleLoad has 
finished (it only calls start(), and in background applicationManager is 
waiting for an event and does the reals setup after onModulLoad())

so what to do - thx in advance

Re: CellTable - how to load just one page?

2011-10-26 Thread David

Only if you know in advance the height of a rendered row. 

Hi Thomas,

I'm close to a solution to providing dynamic retrieval of data via
scrolling.   The CellList example provided in the GWT Showcase does
not work for me because is doesn't let the user immediately scroll to
any portion of the list not already loaded.  Hence you get a water
pump effect as you have to bring the scrollbar all the way to the
bottom in order to request more data.

Right now I am determing the scrollpanel height by multiplying two
constants:   VISIBLE_ITEMS_IN_VIEW * ROW_HEIGHT
I  determine ROW_HIGHT by testing with some data and inspecting the
value of  cellTable.getRowElement(0).getClientHeight().

Do you know any way of determining the height of a rendered row  at
runtime and before setting the height of the scrollpanel ?

thanks
David

Re: Apache Tomcat - Access Files Outside Webroot

2011-10-26 Thread Jmscavaleiro

Hello Alan,

Thank you very much for your reply. My problem is solved.

Unfortunately Apache didn't wrote any exception on catalina.out log.
And yes, you were right, it was a problem of paths. Simply i didn't
create a new File with the absolute path of the destination location,
i was using only the docs/filename.txt assuming that the File classe
would recognize the full path knowing the location in the filesystem
of the app. With Eclipse/Jetty it works but with Apache Tomcat don't.

Once again, thanks for you help, you really convinced me that my
problem was related to paths (Like one friend induced me to). But in
the matteer of fact, the debbug was not easy, the debbug mode with
external server don't work in the server side in the peace of code
where i make this io operations (strange), and the System.out.println
don't show up in the catalina.stdout (strange to and yes, i have
compiled and deployed it on the Apache Tomcat with that modifications
twice).

Thanks,
João Cavaleiro.

 This is something that I do all the time so its your setup that's at fault.

 Are you seeing any exceptions in the log files - logs/catalina.out would
 be a good place
 to look. You can use the standard java.io.*classes such as File ,
 FileReader, FileWriter to make
 the transfers.  I suspect that you have an error in the way the paths
 are created in your production
 server.

 Another possibility is that you have a security manager in place - once
 again, check your logs.

Re: How to get @Prefix value from an Place.Tokenizer? or how to set via clientbundle constants?

ok some questions remain:

i just implemented my AppHistoryMapper. I need one implementation per

with this mock in place: is the code provided bei jens

Re: Apache Tomcat - Access Files Outside Webroot

2011-10-26 Thread Thad

You might want to take this up with the Tomcat user's list, but let me
offer some ideas.

First, I'll second what Alan says:  Read your Tomcat logs.

Second, where is \docs? Inside your $CATALINA_HOME/webapp/MyApp
directory? You can't rely on that directory being writable or even
being there. Tomcat unpacks your war by default, but it can be set not
to do so. Not unpacking is the default in some web servers. I suspect
that Tomcat is not permitting you to copy to a subdirectory inside
$CATALINA_HOME/webapp/MyApp for just that reason.

If the user account that launches Tomcat can read C:\Storage, there's
no reason you can't copy from there. I do this a lot. However I then
use servlets to write the file to back to my user (into an IFRAME or
new window). I don't copy it into a directory my webapp's tree and
tell the browser to access it.

Re: Popup windows printing

2011-10-26 Thread Jeffrey Chimene


On 10/26/2011 1:02 AM, Mike Dee wrote:

I have an app that creates reports, which are basically HTML.  The
reports need to be printed and that is what I'm trying to figure out.

I'm porting an older app - that is more of traditional web app.
Reports are displayed in a page - with a UI wrapped around them.  When
a user wants to print a report, he clicks a print link, which pops
up a window with a printer friendly version (no UI elements).  He can
then selects the browser's print command.  Works nicely.

I'm trying to figure out how to do that in GWT.  I can display a
report.  Printing doesn't work well, because it prints all the UI
stuff too.

I've looked into separate popup windows.  Most of the messages here
recommend against doing it.  Instead they suggest using a Dialog box.
I've tried it and created a Dialog with simply an HTMLPanel.  However,
selecting File-Print (in the browser) prints the entire page (the
entire window).

Any suggestions on a way to do this?


Here's one idea I've implemented. It's amenable to arbitrary levels of 
complexity.


Your UI posts a request to your server on user action (e.g. a button 
click event), and opens the result in a new window:

button type=submit
form action=printTheCurrentReport _target=_blank method=get
!-- Depending on how you manage sessions, you might want a session ID 
token in a hidden field --

/button

Reminder: you should have css for print media.

Re: How to get @Prefix value from an Place.Tokenizer? or how to set via clientbundle constants?



 i guess that is what gwt.create does: generating one mapper per place 
 using the tokenizer code for implementation?


Only one mapper is generated. It contains a large generated if-then-else 
block that delegates getPlace() and getToken() to the correct Tokenizer 
based on the prefix (use -gen compiler option to see whats generated).

I think you only need one mocked mapper. If you want to test an activity 
the mocked mapper would do nothing except tracking method calls and its 
arguments as Thomas said. If your activity has a method configureLinks() 
that you want to test, it only matters that your activity calls 
mapper.getToken(...place for each link that has to be configured...) with 
the correct places as arguments inside this method. The mapper could also 
just return specific test strings per place (e.g. a, b, c, ... so no 
real tokens created by tokenizers) because it only matters that these 
strings are set to the hyperlinks, it does not matter if theses strings are 
correctly generated by the mapper.

My code contains a Hyperlink instance so it would not work without 
GWTTestCase. Its just a short-hand code snippet. In reality you would have 
a method like updateLinkAToken(String token) in your view interface and the 
activity would do:

mockedView.updateLinkAToken(mockedMapper.getToken(new Place())).

As your mockedView and mockedMapper should not have a dependency to JSNI / 
GWT.create() it will work without a GWTTestCase.

HTTPSession Cookie Changed

2011-10-26 Thread Niraj Salot

Dear all,

We are facing some serious issue.

After accessing the application for some time , We are having timeout
issue. Although the timeout is set to 2 hours  , we are seeing that
session are expired only after 15-20 Minutes.

We are using GWT , Spring. our application is deployed on JBOSS 7.0.2.
We are using the HTTPSession in server side only. We are expecting
that during each RPC , browser will send the JSESSION ID cookie with
each request. No seperate coding is done for this.

After our deeper analysis we have found that from client side the
cookie which contians the jSESSIONID is suddenly changed and when it
reaches to server , server create the issue of timeout.

One more thing... The application works fine for couple of users. The
problem only starts when we have more users connected to the
application. Have check memory and CPU stuff. They are fine. nothing
serious over there.

Any help would be greatly appreciated.

Thanks.
Niraj.

Re: Popup windows printing

2011-10-26 Thread Mike Dee

I was thinking about something like that.  In the posts about popup
windows this is seen as a negative because it is tricky to setup
communications between the main window and the popup.  But there
really is no communication needed in this case.

Do you see the popup window as a GWT window or just a straight HTML
window?

 Here's one idea I've implemented. It's amenable to arbitrary levels of

 Your UI posts a request to your server on user action (e.g. a button
 click event), and opens the result in a new window:
 button type=submit
 form action=printTheCurrentReport _target=_blank method=get
 !-- Depending on how you manage sessions, you might want a session ID
 token in a hidden field --
 /button

 Reminder: you should have css for print media.

Re: HTTPSession Cookie Changed

Are you use clusters? reverse proxy?

2011/10/26 Niraj Salot salotni...@gmail.com

 Dear all,

 We are facing some serious issue.

 After accessing the application for some time , We are having timeout
 issue. Although the timeout is set to 2 hours  , we are seeing that
 session are expired only after 15-20 Minutes.

 We are using GWT , Spring. our application is deployed on JBOSS 7.0.2.
 We are using the HTTPSession in server side only. We are expecting
 that during each RPC , browser will send the JSESSION ID cookie with
 each request. No seperate coding is done for this.

 After our deeper analysis we have found that from client side the
 cookie which contians the jSESSIONID is suddenly changed and when it
 reaches to server , server create the issue of timeout.

 One more thing... The application works fine for couple of users. The
 problem only starts when we have more users connected to the
 application. Have check memory and CPU stuff. They are fine. nothing
 serious over there.

 Any help would be greatly appreciated.

 Thanks.
 Niraj.

Re: HTTPSession Cookie Changed

So far I have only seen this in clusters with session replication and a 
round robin load balancer (or multiple DNS entries which is basically some 
sort of round robin load balancing). Sometimes session replication fails 
and a new session is created on a cluster node. You could use sticky load 
balancing to reduce the chance of a lost session because of replication. 

Already searched for JBOSS issues regarding lost sessions?

The latter. This is one of those cases where I think that using GWT to
create the child window doesn't get you anything except a problem
solved! endorphin rush. As I said earlier, the solution can be made
arbitrarily complex, so I'm sure that someone will chime in with a
reason to implement the popup using GWT methods.

To follow-up on the CSS: I've noticed that when there's a reference to a
CSS with media type print, then FF opens a print dialog automatically.
I think Chrome does this too.

Re: jquery?

2011-10-26 Thread t.dave

my $.02 would be that it all depends on what kind of project/app/
website you're building.  if you want to have a true web application
where the page seldom if ever does a full refresh and you want to have
a lot of fancy and super awesome functionality, then GWT is the way to
go.  i've heard that there are ways with javascript to manage your
project well, but my experience with JS is somewhat limited.  i think
it's better for a large web app to be able to work one level of
abstraction higher by coding in java and taking advantage of
everything that brings.

however, if you're building what's really a website and you want to
have just a sprinkling of ajax or a little cool functionality, then by
all means go with jquery.  it's much more lightweight and for simple
things, way simpler.  but from what i've seen i would definitely not
want to do anything of significant size with that.

most likely building a website will be faster, but a web app has a lot
of advantages.  with a web app you can push your state down into the
client and have a stateless server side which helps bigtime with
scalability.  but, depending on your project there may be security
concerns around doing that.

as always, pros and cons both ways but by asking on a GWT list the
answer of which to go with is most likely going to be GWT.  :)

Loading Components On User Request

2011-10-26 Thread Ari

Hi,

Can explain or point me to a tutorial/example that explains how to
load different components on demand within my GWT application?

For example, let's say my GWT application's main/start page is a
home page with a navigation bar at the top and a content container
below. Once a user clicks a navigation button in the navigation bar,
I'd like to load that component into the content container, keeping
the navigation bar as is.

Thanks

Request Factory - Getter issues

2011-10-26 Thread Antoine DESSAIGNE

Hi,

I have 2 issues with the RequestFactory 2.4.0:
- It doesn't seems to support array types as return types,
RequestFooProxy[] getAllFoo() doesn't work
- My Foo base type and thus my FooProxy types have getters without the
'get' prefix, it's name() instead of getName(). This throws an error at
compilation: [ERROR] The method public abstract java.lang.String name() is
neither a getter nor a setter

Is is possible to make it work or should I convert all my arrays into lists
and add the 'get' prefix on all my getters?

Thanks a lot,

Antoine.

Drag and Drop to a RichTextArea / IFrame?

2011-10-26 Thread Derek

I'm trying out some of the fun drag-and-drop stuff in GWT. My current
attempt is to drag a file into a richtextarea, but nothing seems to be
working correctly. It works fine if I use a FlowPanel or some other
GWT widget, but not a RichTextArea despite it have an addDropHandler
method.

Anyone have any experience with this?

My code in onModuleLoad:

DropHandler drop = new DropHandler() {

@Override
public void onDrop(DropEvent event) {
event.preventDefault();

String data = event.getData(text);
GWT.log(text is +data+ and there are
+numFiles(event.getDataTransfer())+ files);
}
};
RichTextArea rt = new RichTextArea();
rt.addDropHandler(drop); // never called even after drag-and-dropping
a file on the rt
RootPanel.get().add(rt);

Re: Chrome 15, GWT DMP Plugin crashes

We have the same issue with Chrome 16.0.912.12 dev-m.
In case we deploy the app or use IE in debug mode  the app works fine!

How do I get a reference to a div and set its inner HTML?

2011-10-26 Thread laredotornado

Hi,

I'm using GWT 2.4.  I have a click handler attached to a button.
Within the handler, I make an ajax call that returns HTML.  I wish to
populate the innerHTML of a div, given the element's id, but I'm not
sure how to do that.

Any suggestions?  I'm currently working with ...


  public void onSuccess(String result) {
  final DivElement contentDiv = (DivElement)
getWidgetById(CONTENT_DIV_ID);
  contentDiv.setInnerHTML(result);
  }
});

The above currently gives the compile error Cannot cast from Widget
to DivElement.  Thanks, - Dave

Re: How do I get a reference to a div and set its inner HTML?

2011-10-26 Thread KevMo

If you know the ID of an element, you can get it by:

Document.get().getElementById(CONTENT_DIV_ID);

Kevin

Re: CellTable styles incorrectly on IE9

2011-10-26 Thread Simon

I can confirm this bug.  Not only does this affect CellTable, but
DataGrid, CellSampler, and Cell Validation classes.  Anyone can
validate this by navigating to Google's own GWT Showcase at
http://gwt.google.com/samples/Showcase/Showcase.html#!CwCellTable in
IE9.

Where can we officially report this bug so it gets escalated
appropriately?  This is very important because I'm in the midst of a
missionary endeavor to convert to GWT at my company in lieu of
JSF(which in IMHO are much inferior paradigms for most applications),
and I'm losing traction over this! :P

Thanks in advance.

  IE9 is supported sinde GWT 2.3.0, what version of GWT are you use?

   If I take the example code directly from the GWT API docs for
   CellTable (i.e. the code for an entry point module that creates and
   displays a contact table with a manual list), the table that is
   displayed has no formatting whatsoever on IE9.  It is just simple left-
   justified text with no styling and nothing is selectable.  If I
   replace the CellTable with a DataGrid, only the paging control
   displays.  On Chrome and Firefox these appear to work.  I have tried
   all combinations of styling, tried replacing the CellTable.Resources
   with my own styling, etc., etc. and it never works.

   Is there a trick to making the new data widgets style properly on IE9?

SplitLayoutPanel and Widgets using UiBinder

2011-10-26 Thread SigmaBlu

I currently have a SplitLayoutPanel (north, west, center, and south).
I am trying to remove and add a widget based on the users interaction
with the centers widget.

For example, when the user clicks on a tables cell, it will remove the
current widget and replace it with another widget. Unfortunately, im
running into an error and it says that i cant add another widget after
the center.  Can someone please point me to right source.  Thanks.

Regards,
SigmaBlu

You need to put an additional layout in the center, like SimplePanel, you 
then remove and add your widget there.
