Unfortunately this reveals nothing at all. No output related to any
JS errors, etc.

In the meantime I found, that accessing the same GWT application using
an iPhone shows the same behaviour: blank page.

How to override module definitions

[Alex Epshteyn]

Surprisingly was unable to find any prior discussions about this...

I'm optimizing my app's load time by merging all my stylesheets into a
single CSS file (then minifying it with YUI compressor), to reduce the
number of HTTP requests.  I'd like to also concatenate all the
stylesheets from third party libraries I'm using into this single CSS
file, but don't see a way to "undefine" the  module XML
elements in these third party modules.

For example, I'm using Fred Sauer's gwt-dnd library, whose module XML
contains



This line instructs the browser to request gwt-dnd.css when this
module is loaded, but I don't want this to happen.

Any ideas?

gwt-presenter and gwt-dispatch Google Groups

[David Peterson]

Hi guys,

Just a note for anyone who's using the 'gwt-presenter' or 'gwt-
dispatch' libraries. Because I can't monitor this group actively (too
much traffic here I'm afraid), I've created a Google Group for each of
the above, so if you want to ask questions, make suggestions, etc,
that's the best forum for it.

The links for the groups are:

http://groups.google.com/group/gwt-presenter
http://groups.google.com/group/gwt-dispatch

The links for the actual projects are:

http://code.google.com/p/gwt-presenter
http://code.google.com/p/gwt-dispatch

See you there.

Re: tying the user interface together using MVP

[David Peterson]

Hi Arthur,

I'm not sure what the 'best practice' is, but using our 'gwt-
presenter' library (http://code.google.com/p/gwt-presenter) I've ended
up tying the Presenters together. In some cases you can be more
generic (use @Named to specify a particular implementation of a common
Presenter subclass), but generally I've found it's not worth the
effort - except for testing.

The downside of binding specific Presenter implementations of course
is that we're back to more work when testing, because we now have
specific implementations being passed into our Presenter constructors,
so they have to be mocked somehow also. The next level of workaround
for that would be to create an interface for your shared Presenters
and bind to that instead, but it's all starting to get a bit silly at
that point.

I think the ideal would be to have this wiring done via the EventBus,
but I'm still working on a good way of doing that...

David

Localization workflow?

[Dobes]

What tools are people using for localization?

For example, currently I've defined all my strings using @DefaultValue
(...) for my Constants interface instead of a properties file - is
there a tool out there to convert an interface into a properties file,
or validation a properties file against and interface?

Has anyone seen a tool to take all the properties from the interface
including the @Meaning annotations and generate/update and excel
spreadsheet from that with columns "Untranslated", "Meaning", "ID"?
This could be used as the first step of the translation workflow.

Next I could merge this file with any prior translations by detecting
any rows where the "Untranslated" or "Meaning" has changed or added
and produce a new Excel file with additional columns "Old
Untranslated", "Old Meaning", and "Old Translation".  This file can be
sent to the translators for translation, who would be responsible for
filling in the "translation" column only.

When it comes back I need another tool to extract the ID and
Translation column data and dump that into the appropriate .properties
file.

I'm thinking I'm not the only one who needs to create and update
translations of their GWT app, but so far my Googling hasn't turned up
any tools for this - especically the first step where the interface
IDs and meanings are extracted out into a useful format.

Anybody got anything to help with this?

Thanks in advance,
Dobes

This would let me concentrate coding sections based on which panel is

Is there any method such as:   public int getActiveIndex() ?

Re: GALGWT, Eclipse 3.5 / Galileo, and GWT 1.7 -- how to add this or any other GWT library to projects?

[philipmac]

Hey, so I've been mucking about with this for say... a couple of
hours.  And, ehh, I never actually used Eclipse until tonight, and I'm
a Perl coder.  So, ahem, take what I say with this in mind...
but, I just right click on my project, go to Properties,
into the Java Build Path, Add External Jars, and stick in the external
jar file into the project.


Although, for some magical reason of which I am unaware of, you have
to use the noredist gears jar.

Give it a try.

Re: Changing a Frame's contents when HTML widgets are clicked.

[Ian Bambury]

Divs of some description.
Maybe as id'd divs in the html. This makes it possible to radically alter
the layout without affecting functionality and allows designers to design
and programmers to program. Even if the programmer is the designer, they can
effect changes in the html and css without a recompile.

Using divs (even if you are just adding flowpanels to other flowpanels)
makes layout easier.

Tables, as everyone knows, got a really bad press when used for layout (and
VPs, HPs and DockPanels and the like are all table-based) and although there
was a lot of rubbish talked, it is easier to get a semantically significant
layout using divs (and that means text-readers - and search engines - can
make more sense of it)

DockPanels are something else again - they tempt programmers away from
better structured code IMNSHO, creating too many classes at the same level.
Which is probably fine while you are playing about and learning, but makes
maintenance in real-life applications a right bugger.

And most of these table-based panels *require* that you set heights and
widths in the code unless you want all the TDs the same size. If you create
three cells in a VP the only way to set the heights is in code - unless you
shove other widgets in there and let them expand when you set the height of
those widgets (but then if you decrease the size of the widgets, in some
browsers the table won't shrink back).

There are other consideration due to the way GWT works which means that in
large apps you might get significant performance hits if, say, you are
creating a lot of nested widgets. Using a widget has some overheads and if
you don't need to use a widget then it's probably a good practice not to use
a widget. Even if you need to do stuff dynamically in code, you can use the
HTMLPanel and shove divs in that.

A quick test showed that divs with ids in an HTMLPanel is 2.3 times faster
than div elements with ids in another div element and 13 times faster than
labels with ids in a verticalpanel. 10,000 took about 65ms, 150ms, and 850ms
respectively (averaged over a number of tests). That was in Chrome. IE7 took
between 35 and 40 seconds to put labels in a VP. Users start to notice
delays like that.

There may be quicker ways of coding it though, I just knocked 3 examples
together, but it probably gives a good idea.

I compile the project out and run it in firefox, and pull up the error
here in the javascript:
==
function $setHTML(this$static, row, column, html){
var td;
$prepareCell(this$static, row, column);
td = null.nullMethod();
$internalClearCell(this$static, td, html == null);
if (html != null) {
null.nullMethod();
}
}
==

in particular this line:
td = null.nullMethod();

I've looked around, and can't find anything which really explains to
me what's going wrong.

Here are the methods that I've overwritten

==
@Override
protected void prepareRow(int row) {
if (row < 0) {
throw new IndexOutOfBoundsException(
"Cannot create a row with a negative index: " + row);
}

int rowCount = getRowCount();
for (int i = rowCount; i <= row; i++) {
insertRow(i);
}
}

@Override
protected void prepareCell(int row, int column) {
prepareRow(row);
if (column < 0) {
throw new IndexOutOfBoundsException(
"Cannot create a column with a negative index: " + 
column);
}

int cellCount = getCellCount(row);
for (int i = cellCount; i < column; i++) {
insertCell(row, i);
}
}

@Override
public int getCellCount(int row) {
if (row < 0) {
throw new IndexOutOfBoundsException(
"Cannot find a row with a negative index: " + 
row);
}

// Initialize - 0 cells in a row
int count = 0;

// check if the row exists yet
int rows = getRowCount();
if (rows >= row) {
count = getDOMCellCount(row);
}

return count;
}

// and the constructor
public InvoiceGrid () {
// set the headers
setHTML(0,0," ");
setText(0,1,"Invoice Number");
setText(0,2,"Client Name");
setText(0,3,"Invoice Date");
setText(0,4,"Due Date");
setText(0,5,"Terms");
setText(0,6,"Ageing");
setText(0,7,"Amount");
setText(0,8,"Status");
}

Can anyone help me with this? Any clues as to what I've done wrong
here?

Thanks guys.

Re: JSNI Issue

[Robert Zaleski]

We pass the scope, the this, around with callbacks.  We started doing
this before we tried GWT as it's allot quicker to pass two variables
(scope and cb) instead of making a closure.  Ext.js also uses this.
Then the caller just does

cb.call(scope, extra args);

I've done this a few times in GWT and it works.

If you want an object you can call multiple methods on, I'd use the
Exporter stuff at

http://code.google.com/p/gwt-exporter/downloads/list

It lets you new and call an object multiple times.  It also will
export your static methods for you, and let you pass objects into
them.  So it's nice.  I currently use a mixture of both to integrate
with some legacy code.

Aaargh!

I was really hoping not to have to do that --- my layout is complicated
and contains lots of CSS stuff, and trying to redesign all that so it's
done in code rather than CSS would be a nightmare. Also, slow. Oh, for a
real boxes-and-glue layout system...

Anyway, thanks for the help --- I shall go investigate alternatives. It
may be that I can query the size of the TabPanel's container at run
time, which would mean that I don't have to redo *all* the layout code.
Sigh.

You make a good point here. I think it would make sense to have a hook that
developers could implement here for such failure cases.

Would you mind filing an issue for this in the Issue Tracker? That way,
you'll automatically be notified of updates to the issue, and I can

Allow other domains to access a GWT application (running on Google App Engine)

[Everett]

Hi All,

I would like to allow a particular set of other domains to access my
GWT application (running on Google App Engine).  Is this possible with
GWT and how to do it?

For example:

Let's say I have the StockWatcher application from the tutorial
running on http://stockwatcher.appspot.com.  Part of the page
StockWatcher.html are the lines


...


The application is run as http://stockwatcher.appspot.com/StockWatcher.html
and everything works fine.

Now let's say I want to also allow example.com to run my StockWatcher
application.  I tell them to make a copy of StockWatcher.html in their
root directory and change the lines above to


...


The application is run as http://www.example.com/StockWatcher.html
and, ideally, everything works fine.

I tried a scenario similar to this but when I viewed
http://www.example.com/StockWatcher.html I didn't see the StockWatcher
application and no errors were reported.  When I view the source of
the page everything looks fine to me.

My questions are:

1. Is this kind of application deployment possible in GWT?
2. If so, how would you go about doing it?  I'm a developer new to GWT
so I just need a kick in the right direction.
3. How would you get the example.com domain to check it against a
whitelist of allowed domains in the GWT application?

Thanks for your time,
Everett

GALGWT, Eclipse 3.5 / Galileo, and GWT 1.7 -- how to add this or any other GWT library to projects?

[Julian]

Hi all, firstly the GWT / AppEngine plugin for Eclipse is sensational.
To be able to deploy to production so easily is amazing.

However a basic question -- how do you add other GWT libraries?

I wanted to extend the template given by making a geolocation API call
in gwt-gears I'm struggling to figure out where to add gwt-gears.jar.

1. I added it to my project's lib folder along with the other jars
that were included in the default project but they are not presented
through the GUI as available to add.
2. Adding them as 'external jars' solves the IDE syntax checking
issues but then unsurprisingly crashes in hosted mode.

I'm missing something basic I'm sure about how to add GWT libraries --
anyone have any suggestions?

thanks!
(This is for GALGWT, Eclipse 3.5 / Galileo, and GWT 1.7)

Issue in documentation code

[mthakershi]

To moderator of this group/documentation:
-

-
for (int i=0; i>symbols.length; i++) {
  if (symbols[i].equals("ERR")) {
throw new DelistedException("ERR");
  }

  double price = rnd.nextDouble() * MAX_PRICE;
  double change = price * MAX_PRICE_CHANGE * (rnd.nextDouble() *
2f - 1f);

  prices[i] = new StockPrice(symbols[i], price, change);
}

GWT + gears + eclipse, problem.

[philipmac]

Hey,

So I pulled the latest Galileo Eclipse release, and obtained the GWT
plugin from dl.google.
The demo helloServer app works without problem, and I have played
around with things a bit and it seems fine with the hosted browser and
so on.

I wanted to start using the Gears code, and it seems that there is no
plugin for this.  Why is this the case?

Oh well, so I pull the gears gwt stuff, and unpacked it, and dropped
the jar files into the dropins folder on my eclipse installation.
I create a project called test, and make sure it performs its
helloServer ok.

On the top of my Test.java file I then add
import com.google.gwt.gears.client.Factory;
import com.google.gwt.gears.client.database.Database;
import com.google.gwt.gears.client.database.DatabaseException;
import com.google.gwt.gears.client.database.ResultSet;
because I will be using that later.

I also add
 
to my .gwt.xml file.

I reload the live server thing and :
"Unable to find 'com/google/gwt/gears/Gears.gwt.xml' on your
classpath; could be a typo, or maybe you forgot to include a classpath
entry for source?"
And it hangs on the web page at the point where it should be making
the TextField.

I suppose I am not understanding how this dropins folder is meant to
behave.

Why is it looking for Gears.gwt.xml?  There is no such file in the
gears.gwt dist.

Anyway, struggle onwards, right click on my project, go to Properties,
into the Java Build Path, Add External Jars, and stick in the external
jar file gwt-gears.jar into the project.

So, now the IDE seems a little happier with things.  I have a warning
there saying I am not using the gwt.Gears stuff, and am including it
for no reason but its happy that it knows what gwt gears is now.

The live browser thing is a total basket case now.  It no longer can
even find test.html its giving me a 404 and masses of error messages.

Ok so.. I run a compile, setting the it to debug level
information, and it compiles happily.

Note, I have not modified the code really at this point, its still the
helloServer stuff I started off with.  I just added jar file to the
project, modified the xml file, and added a few includes.

I'm running gwt-gears-1.2.1, gwt 1.7, my vm with which I run eclipse
is java 6 from sun, in Eclipse version Galileo, on Ubuntu Jaunty, on a
64 bit machine, compiling against the 32bit libs as seemingly demanded
by gwt.

Any ideas?

Re: Who is using smartgwt?

[ckendrick]

Tercio, might be a language gap problem here, but canEditCell() is an
override point that a Java developer can override purely in Java.  The
default behavior of canEditCell is well documented, and a developer
should always look *first* at the documentation, not the
implementation, in understanding what a method does.  Otherwise it is
easy to make apparent "progress" when in fact you are relying on
unsupported functionality.

Again, I highly recommend working through the details of drag in drop
between large groups of users so you can discover why it is necessary,
when data volume is high, to creating caches on behalf of individual
widgets in the view.

Re: IE8 and GWT 1.7

[Sumit Chandel]

Hi Karim,
I wasn't able to reproduce this problem using GWT 1.7.0 / WinXP / IE 8. The
starter application generated by the Google Plugin for Eclipse works as
expected in hosted mode and all supported browsers. Are there any other
symptoms of the problem you're experiencing that you could tell us that
would help figure out what's going on?

Also, have you changed the code from what was initially generated by the
plugin?

Regards,
-Sumit Chandel

SmartGWT 1.2 Tile Sort &Filtering Example Question Fuzzy Search / (Maybe Bug)?

[Jan]

Hi everybody,

I am just new to GWT and experiencing a little bit with SmartGWT,
implementing and trying to change the Tile Sort & Filtering Example
from the Showcase 
http://www.smartclient.com/smartgwt/showcase/#featured_tile_filtering

I am trying to implement the above example with a fuzzy search but
without the extra SearchItems, which causes the FuzzySearch to fail
and draw back on an EQUALS search.


Everything works fine with the example, but here comes my  'error' /
'bug' :
Here is an excerpt from the code from the showcase example:



final DynamicForm filterForm = new DynamicForm();
filterForm.setIsGroup(true);
filterForm.setGroupTitle("Search");
filterForm.setNumCols(6);
filterForm.setDataSource(AnimalXmlDS.getInstance());
filterForm.setAutoFocus(false);

TextItem commonNameItem = new TextItem("commonName");
SliderItem lifeSpanItem = new SliderItem("lifeSpan");
lifeSpanItem.setTitle("Max Life Span");
lifeSpanItem.setMinValue(1);
lifeSpanItem.setMaxValue(60);
lifeSpanItem.setDefaultValue(60);
lifeSpanItem.setHeight(50);
lifeSpanItem.setOperator(OperatorId.LESS_THAN);

SelectItem statusItem = new SelectItem("status");
statusItem.setOperator(OperatorId.EQUALS);
statusItem.setAllowEmptyValue(true);

filterForm.setFields(commonNameItem, lifeSpanItem,
statusItem);

filterForm.addItemChangedHandler(new ItemChangedHandler() {
public void onItemChanged(ItemChangedEvent event) {
tileGrid.fetchData(filterForm.getValuesAsCriteria());
}
});




Three search items are created and fit together in the filterForm.
Using the form and entering just a part of a Common Name, will break
down the results with each letter I type.

Now comes the bad part:

I do not want the lifeSpanItem and statusItem any more. So I change


filterForm.setFields(commonNameItem, lifeSpanItem, statusItem);


to

filterForm.setFields(commonNameItem);


Now, trying to enter just a part of a Common Name will not break down
my results with each letter I type, but instead the behaviour is like
commonNameItem.setOperator(OperatorId.EQUALS)


So what I am saying is that the search works fine for searchItems
greater than just one TextField. My workaround therefore was to create
a HiddenItem as follows:

HiddenItem tagsItem = new HiddenItem("tags");
tagsItem.setOperator(OperatorId.EQUALS);

filterForm.setFields(commonNameItem, tagsItem);


Now I think that this can't be right. Now am I missing something? Do I
have to use .setOperator on commonNameItem, if only commonNameItem is
present? If yes: Which OperatorId should I choose?


Thank you very much for your help,

Greets,

Jan

Re: Struts 1.2 and gwt

[Sumit Chandel]

Hi suzy,
There is nothing stopping you from using GWT in your Struts application. One
point of conflict I could think of is controlling application flow, as
Struts does seem to prescribe a Web 1.0 style navigation flow, however you
can definitely add GWT components to your existing Struts pages to enhance
them.

In your case, it seems like you simply want to use GWT to display data
within your Struts page. You can do this by simply coding up your GWT
component (both the widget layout and style itself along with the logic to
grab the data to be displayed from the page), and binding the component to
an element in your Struts page. You can read more details about how to bind
the component to your Struts page in the documentation linked below.

Organizing Projects - HTML Host Pages (same concept applies to a Struts
page):
http://code.google.com/webtoolkit/doc/1.6/DevGuideOrganizingProjects.html#DevGuideHostPage

Hope
that helps,

Re: GWT Deployment on Web Hosting Sites

[Sumit Chandel]

Hi Kenneth,
As Dobes mentioned, you can definitely use any hosting service, like
GoDaddy, to deploy your GWT application. Also as mentioned, GWT generates
regular JavaScript and HTML files than any hosting service provider should
be able to handle. If you're using GWT RPC, you will need a hosting service
that provides a Java server-side environment, supporting the Servlet 2.5
specification.

For more details on all the moving parts of a deployed GWT application, both
with an RPC backend and without, check out the deployment documentation at
the link below.

Sinking new HTML 5 DOM events?

[Eric Kidd]

GWT is a really clever piece of compiler technology!

I'm currently experimenting with HTML 5's  tag and GWT. For
the most part, this was very easy to get running. But event-handling
has been a major headache.

In particular, I'm trying to add a listener to "ontimeupdate", which
is called whenever the current playback time changes. In JavaScript,
the code would look this:

# Tested in Firefox 3.5. (Will generate tons of alerts. Be
warned.)
var video = document.getElementsByTagName('video')[0];
video.addEventListener("timeupdate", function (event) {
window.alert("Time: " + video.currentTime);
}, true);

I've defined an appropriate set of classes (TimeUpdateEvent,
TimeUpdateHandler) and added a addTimeUpdateHandler function to my
Video widget. But this isn't enough to make things work--my timeupdate
handler is never called. (Code is attached below.)

Further investigation reveals that I'm still missing quite a few
pieces:

  DOMImpl::eventGetTypeInt - I need to add an entry for "timeupdate".
  DOMImpl::sinkEvents - I need to call addEventListener
("timeupdate", ..., true).
  Event - I need to add a ONTIMEUPDATE constant.

Is there an easy way to work around this without patching my local
copy of GWT? And would it be worth either (a) making the list of
events extensible at runtime, or (b) adding a list of events taken
from the HTML 5 standard?

Thank you for such an interesting toolkit, and for any advice you can
provide on supporting custom DOM events!

Cheers,
Eric

=== begin Java code ===

public class Video extends FocusWidget {
// ... lots of code removed
public HandlerRegistration addTimeUpdateHandler(TimeUpdateHandler
handler) {
return addHandler(handler, TimeUpdateEvent.getType());
}
}

public interface TimeUpdateHandler extends EventHandler {
void onTimeUpdate(TimeUpdateEvent event);
}

public class TimeUpdateEvent extends DomEvent {

private static final Type TYPE =
new Type("timeupdate", new 
TimeUpdateEvent());

public static Type getType() {
return TYPE;
}

@Override
public Type getAssociatedType() {
return TYPE;
}

@Override
protected void dispatch(TimeUpdateHandler handler) {
handler.onTimeUpdate(this);
}
}

First problem is that you are asking a JavaScript question in a GWT group
:-)

Second problem is that your webpage will loop, endlessly loading and
reloading. This a pretty basic a mistake, so maybe it would be a good idea
to search for some JavaScript tutorials or sign up to a JavaScript
beginners' group.

Re: how to deploy a GWT Application online?

[sam]

Thanks Jason and Lal,

When I run my application in eclipse it works fine.

Then, I compiled the application by clicking the red icon ie 'GWT
Compile Project'. On settings, I picked 'log level'=all, and 'output
style'=detailed.

Finally, I get the message:Compilation succeeded -- 97.258s  after
bunch of other lines.

Then, I took the content inside the 'war' folder and posted it online
using dreamweaver.

Clientside of the application works fine.

However, when I click on something that requires to get data from
server Implementation method, then it fails and I get the error:

com.google.gwt.user.client.rpc.StatusCodeException:

As for hosting server, my server has 'apache 2.2.11.' My computer also
has WAMP with 'apache 2.2.11'.

Is there a way to deploy GWT application online with apache 2.2.11?

I am new to this, thanks for the support.

You should only ever have one widget in the cell. The method setWidget(int

Re: ImageBundle using AlphaImageLoader don't allow events to fire properly

Thanks for reporting this, Damon. For what it's worth, this shouldn't be an

Re: Linux 64bits package?

[Lucas Neves Martins]

Rajeev Dayal says: ... the next release of GWT will no longer require
that you use a
32-bit JVM. It will support a mode of execution known as
"Out-of-process-hosted-mode". Instead of debugging your application
using
the hosted browser, you'll be able to debug it while it runs in a real
browser. Since the hosted browser will no longer be required, neither
will
the 32-bit SWT libraries that we bundle. If you're adventurous, you
can try
out this functionality right now - check out the GWT source, and do a
trunk
build. It should work with the plugin.

Good luck!

Re: Creating Reuseable Modules

[Lucas Neves Martins]

Yeah I know the feeling,

My app was taking around 20-30 seconds to load for the first time -
after the first load it was nearly instant

I've tested with Google Page Speed and Page Activity as well, and I
come to realize that the biggest problem is the huge amount of JS
scrips ( at least for me ), Gzip compression helped a lot, in my case,
around 7-10 seconds.

As the GWT application itself is just pure JS in the client side, a
"solution" I've used that helped a lot the user experience, is to load
the application in the background.

In my case, I load the login screen first - and it does it very
quickly, around 1-2 second(s) - and while the user is still logging in
the application I load all the other parts of the application,
starting from the parts I think the user will use first. So while the
user logs in, and take a look to the main page, all the application is
loading without his perception - except for the firefox status
spinner : P

And then 10-15 seconds comes to be a acceptable time, since my users
take just around that time to make a login and try to use any other
funcionality after doing it.

But of course, I agree that GWT could be better in both performance
and best practices, but if you look at the generated code, you will
see that that ship is sailed.

The browsers are not so compliant to the standards as they could, and
the guys from the GWT team can't do miracles.

Take a look at gzip compression and and partitioned loading for gwt
apps,

I know I didn't actually answered you question, but this might help
your performance.

Good luck!

Prevent duplication of records on refresh

[Rahul]

Hi,
I am reading values from the database(sql server) and then showing
them on my webpage. Reading is done on the server side and showing
them its on the client side.

The problem i am facing is that whenever i refresh the page, all the
values get duplicated on the web page and it keeps going on.

How should i proceed to prevent this? would it be a javascript module
i need to put in? or a java code in my client?

Re: Compilation failing

[Lucas Neves Martins]

You can try a debug from the entry point,

check all the places where you replace layouts onto the html page.

I don't know if your app contains sensitive data or information, but
if not, post some code - or the whole code - so I can help you.

Best if luck!

Re: Creating and Importing GWT Independent Modules

[Lucas Neves Martins]

I am not a GWT expert, but I don't think this is possible.

But if you want to make life easier you could use a "ant task" to
automate those jar builds, copying, and classpath updating.

With "ant" you can do most anything you could with a ShellScript, you
know, java project wise.

To help debugging, you can export every jar with the sources inside,
there is a checkbox on the eclipse Jar export wizard.

Boa sorte!

Re: Creating and Importing GWT Independent Modules

[Lucas Neves Martins]

Yeah! It worked!

Sorry for the waiting, there was a reshuffle and I was working in
another project for a little while.

But your step by step guide is very useful, and the discussion heped
me too.

I followed your steps and got the class acessible in the main project,
but when I booted it, I got a nasty null pointer exception,  so when I
read your next post : " Only code that can be cross-compiled into
JavaScript should be used when
performing a GWT compilation ", I realized how obvious the solution
was.

I don't know yet if there are any other ways ( I believe there is ) ,
but I made my class to implement the "EntryPoint", the everything gone
smoothly well. I left the "onModuleLoad" method empty.

Thanks a lot Chandel , I will continue my journey on the GWT.

Re: Compilation failing

[Rahul]

Hi
Some more information

I just checked that whenever i am compiling my application all the xml
files which i have stored war directory are deleted. So there are no
xml files and this is why i am getting the error. also is there any
way that those xml files are not deleted when i compiling?

But now i am hosting it on the tomcat server, where should i paste my
xml files. I pasted them C:\cbesb-2.1\tomcat\webapps\test10\test10,
( test 10 being my application name) but its not showing on the
browser.

any suggestions?

Re: ValueChangeHandler / History does not work in Opera :-/ (neither stable or beta)

[twdarkflame]

The workaround seems to work fine :)
Tested on the demo project, and it responded to everything.
Ive put it on my main project and I'm pretty sure its working fine
there too. (cant know 100% yet, as the history stops responding on
certain functions...I suspect its due to a another part of my code
crashing in though)

Are there any side-effects of this I should be aware of? Will future
gwt upgrades change/effect this?

Cheers,
Thomas

Re: At new item to a list at each position

[Tobe]

Ok, but in this case inside the (1,0) there can be some more Elements
and always the last one is the nested FlexTable I need. I
tried .getElement().getLastChild() but can't cast the received Node to
a FlexTable.

Re: Compilation failing

[Rahul]

Hi thanks for the reply

I am using an Windows XP machine and i am developing in Eclipse using
the GWT toolkit. I am using the default google explorer which one gets
while using the hosted mode. Everything was running perfectly while i
was running it. But when i clicked on the Compile/Browse button the
application gave me this error.

The error is happenning in the following part of functionality. I am
parsing an xml document and storing its attributes in a string.Then i
am reading an substring from the main string. The line says string out
of index ( from searching on google) says that there is no character
of the string on that place. When checked now, the is no value being
stored presently in the string variable, which is odd, because i
created backup of the application before hitting on compile/browse
button and its still working fine with no errors.

any ideas how should i proceed.

Re: Compilation failing

[Ian Bambury]

What OS are you developing in? What browser are you testing the compiled
code in?
I suspect that you are not developing in Windows and are testing compiled
code in IE. IE will report errors that other browsers don't (yeah I know
'typical IE', but there again if it didn't report errors when it should that
would be 'typical IE' too).

If that is the case, then you need to compile with the  -PRETTY option and
find out where the error is. Or try it on a Windows machine where you will
get a proper error report.

If not, then more information would be useful.

Re: Who is using smartgwt?

[Tercio Filho]

ckendrick, is canEditCell() a behavior or a feature?

protected native boolean canEditCell(int rowNum, int colNum) /*-{
var self =
th...@com.smartgwt.client.widgets.basewidget::getOrCreateJsObj()();
return self._canEditCell(rowNum, colNum);
}-*/;

Damn, it's behavior is inside JS code.

I'm not saying that a widget cannot have a cache, I'm saying it just
can't manage it, well, it can, but shouldn't...

Regards,

Tercio.

Suddenly getting exceptions during compile in TypeOracle annotation processing

[martijn.spr...@gmail.com]

I'm suddenly getting strange exceptions when compiling my application
that uses EJB3 objects with annotations and Gilead. The exceptions
seems to happen for different annotation objects each time, however
it's always for the same reason: NPE in the TypeOracleMediator.

I've tried this with the old version of Gilead (Hibernate4gwt 1.1.1)
and with the new version. I've also tried this with GWT 1.6.4, and
1.7.0. In every case it's giving me the same NPE.

Nothing significant has changed in my code, I've just made some
general improvements over the last few days which are working find in
hosted mode. However compile seems to be screwed up.

Does anyone have any idea what is going on here?

 The following is my compile script:
#!/bin/sh
APPDIR=`dirname $0`;
java -Xmx768M -XstartOnFirstThread -cp "\

Re: Who is using smartgwt?

[ckendrick]

Sorry Tercio, I can't spend more time helping you understand the
architecture here, but suffice it to say, try building the example I
suggested (drag and drop between two very large user groups that can't
be loaded in advance) and you'll see why widget-specific caches are an
absolute necessity.

Each widget is looking at a particular subset of the data available
from the model, managed by a ResultSet which serves as a projection of
the model data needed for that particular view.  You will find the
same approach in every system that handles large datasets, from Swing
to JDBC and everywhere else - it's really worth your time to
investigate this and understand it.

I'd also appreciate it if you could stop asserting things that are
just clearly false.  SmartGWT has many, many Java override points that
allow you to deeply customize behavior - not "getters/setters" but
fundamentals like which cells are editable (listGrid.canEditCell()),
how data is transmitted (various DataSource APIs), many aspects of how
HTML is generated (getInnerHTML, cellFormatters, many others), and of
course, countless events.   I think you have some misconceptions which
date back to right after 1.0 was released - not every override point
from SmartClient is yet available in SmartGWT, but we are getting
closer to that all the time.

Re: At new item to a list at each position

[Ian Bambury]

Can we try this in words, not html :-)
You have an outer table with 'Insert' buttons in the even rows (0,2,4,...)
and child tables in the first column of the odd rows (1,3,...)

To access the first child table, you use

FlexTable inner = (FlexTable)outer.getWidget(1, 0);

Re: Caching on AppSpot.com?

hmmm... it seems the images are loaded on demand, no cache on the App

Re: At new item to a list at each position

[Tobe]

Ok, the .parent() is wrong because I have to access the tableInner
inside tableOuter. The sourcecode of tableOuter is the following:









add outer







outer








add
inner










add outer






, but how can I access the inner table in the first column of the
second row which has the class="divInner" attribute?

Creating Reuseable Modules

[Rodders]

GWT comes with "default" CSS. If I create a bunch of reuseable Modules
(packaged as Jars for use by some of our other internal development
teams) with our own corporate style, the compiled application loads 2
stylesheets (the "default", and "company" for example).

If one of our development teams uses those Modules to create a new app
and adds some CSS specific to that app the compiled application loads
3 stylesheets ("default", "company" and "application").

These stylesheets are not "minified" or combined, this can't be
correct as Google's own page performance tool states that HTTP
requests should be reduced and css files combinded - I must be doing
something wrong?

However, one of the GWT example apps I've seen is loading over 1Mb
data in 59 http requests and takes about 11 secs to load...

Can anyone point me at a good tutorial on how to create reuseable
modules that don't break web app performance best practices?

Thanks.
Rodders

Re: How to split a large application?

[Vivian Steller]

Hello David,
hey folks,

we figure exactly the scenario you describe here with our application.
It's similar to a portal based application as you describe it.

Basically, what we struggle with: Say we compile the main application
with some portlets pre-installed resulting in a single JS file. We
also provide additional modules/portlets that the user might want to
install. These modules, however, have a completely different lifecycle
than the rest of the portal. Now, if we'd compile the additional
portlets one by one, wouldn't that result in a whole bunch of
duplicated JS code e.g. for JRE emulated classes? Next, the JS code is
of course obfuscated so the names of our Java types vary from
compilation to compilation. If I'd compile each module separately it
wouldn't find any existing class from the portal application. Even
worse, I thought it would just duplicate the portal applications
classes into the portlet JS code (of course, assuming we have a call
dependency to the portal application).

The only solution to this problem we currently think of is to trigger
a complete re-compilation of the app at runtime. For instance, we try
to implement a registry where each module/portlet Jar registers and
once the registry detects changes it triggers re-compilation of the
complete javascript files. We'd likely do that in a servlet context
listener or something equivalent.

Has anyone tried something similar already? Has anyone similar
problems and/or other solutions?

Thanks!

IE 7 'undefined' is null or not an object

In IE 7, I am getting the "'undefined' is null or not an object"
error. I have googled and searched for answers, but nothing has come

to search first. I am using GWT 1.7 and app engine 1.2.2

Android (1.5) Browser displays empty page

[Michael Wiedmann]

Our GWT 1.7.0 works quite fine in "standard" desktop browsers like FF,
IE, etc. Problems occur if I try to use Androids built in webkit
browser (both using the Android SDK emulator and a real hardware
device).

The log (spam level) in hosted mode shows that a bunch of CSS and JS
files being requested and successfully delivered. The last request I
see in the log looks like:

200 - POST /OML/SessionService (...) 14 bytes

The Android browser does not display anything (page remains blank), a
standard browser displays a "login" page at this point.

Any hints howto resolve this problem would be highly appreciated!

Michael

TabBar design

[MamboJumbo]

I was recently trying to understand how the beautiful tabbar with
rounded corners is implemented in http://code.google.com/p/google-web-toolkit/.
DecoratedTabPanel is rounding corners for the tab bar but not for the
buttom panel. Can anyone point how to make bottom panel top corners
rounded like at the above mentioned website?
Thank you.

Re: Is there a way so I can use "Project>Run As>Run on Server" functionality while using the new GWT eclipse plugin?

[Jason Parekh]

Hi jmpeace,
Could you explain your use case a bit more (so in the future, we can better
support it.)

My understanding is you'd like to do infrequent GWT compiles and package
this into a WAR and run it on a server.  Is the server GWT's jetty instance
or your own app server?

You may be able to use Keith's instructions from
http://groups.google.com/group/Google-Web-Toolkit/msg/9ce13140f71e2100 if
you want to run this on your own app server.

Thanks,
jason

Hey Sam,
As Lal explains below, creating the war file and deploying it into Tomcat

Could you explain how you tried to deploy it online?  How did you package it

Have you tried any other apps on your server that are able to access the

remove all margin/border of FlexTable

[Tobe]

Hi,
I have a FlexTable with some rows and used setStyleName() to set a
background-color from a CSS file. I also set margin and border to 0 in
the CSS file for all elements, but still have something like margins
around the rows of the FlexTabel where I see the background-color of
the other elements where the FlexTable is located in.

It's basically the same as what you described above, without the need
for Java statics.

Re: GWT-Maps -> Is this a desired behavior?

[Eric Ayers]

Hi Paul,
Take a look at this demo in JavaScript:

http://code.google.com/apis/maps/documentation/overlays.html#Custom_Overlays

The demo code is called 'CustomOverlayDemo' in the HelloMaps API demo

I think part of the problem is that your code draws into the viewport
with pixel values - you need to work with lat-lng values for things to
correctly drag around in the map.  Also, you are re-creating the divs
inside of redraw() - the should be created in initialize().

-Eric.

Re: JSNI Issue

[CI-CUBE]

My workaround is to use static methods (1 for each Callback) in the
base class that redirect the request to virtual members of a static
member object. This introduces some overhead but works... anyway is
there some advice how to use a true member method in an assignment to
a JS callback?

TIA,

   Ekki

Caching on AppSpot.com?

[CI-CUBE]

Hi,

I'm running an App on AppSpot.com that is controlled by an external
XML. However the App doesn't reflect any changes of the XML. Is there
an App Engine cache I might reset? Strange thing - I modified this XML
by the end of last week and the mods were considered immediately...
does this make sense?

Re: formating ListBox text

[BobM]

No, appending HTML   to a string doesn't work to solve my
problem.  However, I have found if I append a period and a space (sort
of as a single character) each space is retained because of the
protecting period, I can get close enough for my purposes.

If I could now set the font to a monospced font like Courier, I would
be "home free", I think; but that seems not to be possible at present.

I feel like I have "solved" my problem, for now.  (Kind of sloppy, but
it works.)  Thank you.

Re: Where is the server log ?

[Daniel Jue]

While searching for something else, I saw some gwt directories in the Local
Settings\Temp dir, which had some log files in them.

C:\Documents and Settings\MyName\Local
Settings\Temp\gwtc2884477077954149866.tmp\myModuleName\shell\gen

These look like logs for the RPCs.

Re: Where is the server log ?

[Trevis]

This isnt a direct answer to your question but i think that this is
the root of what is going wrong. Class instances that you send to the
client have to play by the rules of GWT.  The class cant have imports
that are not available on the javascript runtime code.

import javax.persistence.Entity;
import javax.persistence.Table;

those classes are almost certainly not in the limited environment.

Re: formating ListBox text

[BobM]

Hm ... The data, name and location, are two fields of a database
row.  I retrieve several (related) at a time from the database and put
the two key fields into the ListBox and then select which one I want
to use thereby selecting the rest of the fields from the database
record to display in other TextBoxes on the page.  ListBox seems just
the right thing for that.  However, if I can select from a table and
use the index (row number) from the selection to pick off (out of an
array) the record containing the other fields to display that would
certainly work.

I will look into that.

Thanks.

O3DJS Modules and JSNI

[CI-CUBE]

Hi,

I'm facing a problem when using O3DJS module 'namespaces' within JSNI
assignments:

That's what works:

$wnd.x4_view_loadAppCB =
@com.egr.x4gpl.apps.saturn.client.Application::_viewLoadCB();

That's what I wanna have (using the O3DJS module id's):

$wnd.x4.view.loadAppCB =
@com.egr.x4gpl.apps.saturn.client.Application::_viewLoadCB();

There's no error message I could provide...

TIA,

   Ekki

Re: How to determine pixel size of Label widget at run time?

[Ian Bambury]

Unless you set the label to display:block it will expand to the width of its
container (it is actually a div). With display:block it will just be as wide
as it needs.
Why can't you move it once it is added?

Re: question from a novice in GWT

Well, you could still use the method I outlined by using a Frame
(iFrame) and load your site in it. So, you would have a GWT shell.

Re: How to determine pixel size of Label widget at run time?

[Mike Jacobs]

The label offset width is zero prior to adding to the root panel and
unusually large after adding it.  The width is supposedly 761 for a
string of "~~testing~~".  I will experiment with this a bit more but
this width seems like it might be the width of the root panel at the
time.

Re: formating ListBox text

[BobM]

ListBox has methods allowing me to set and get the selected index.  I
cannot find any similar facilities in HTMLTable.  Am I overlooking
something?

Can I use HTML to generate a non-breaking space to append to a String
to put into the ListBox to force formatting of the string?  Maybe I
will try that later today.

For now ListBox still looks to be the cleanest tool for my needs - IF
I can get the text properly formatted.

Re: How to determine pixel size of Label widget at run time?

[Mike Jacobs]

Once I added the label to the intended container (the map pane in the
Google map API), the width was calculated correctly.  Since I cannot
move the widget once it has been added, I add it to get the dimensions
and then remove it before adding it where it belongs.

Thanks for the help.
