Re: Adding a MouseOverHandler to CellList

2011-08-03 Thread Sébastien Tromp

Thanks, that's what I was looking for. Sorry to have overlooked that.
For information, I used this and the code snippet from
therehttp://stackoverflow.com/questions/4699232/mouseover-of-flextable-with-gwt
to
build a custom popup, and hide it on mouseout.

 AbstractCellT.onBrowserEvent() should be called if you call
 super(mouseover) in the constructor of an AbstractCellT subclass.

showRelativeTo doesn't work the first time

2011-08-03 Thread Dennis Haupt

there seems to be something wrong with my popups. the first time i try to
show a popup via showRelativeTo(someWidget), it simply doesn't show with
firefix and chrome. ie9 works fine.
both times, the coordinates are equal. PopupPanel.setPopupPosition is called
with the same parameters, so it's not an out-of-screen-coordinates problem.
any hints?

Service method that returns HashMapString, Object can't carry anything but String

2011-08-03 Thread Christophe Marchand

Hi !

I have a Service method that returns a HashMapString, Object. I have to put 
String, Integer, Long, BigDecimal and Date as values in.
If I put only String, it works perfectly.
If I put anything else, I have a serialization problem :
com.google.gwt.user.client.rpc.SerializationException: Type 
'java.math.BigDecimal' was not included in the set of types which can be 
serialized by this SerializationPolicy or its Class object could not be loaded. 
For security purposes, this type will not be serialized.

Any idea ?

Thanks in advance,
Christophe

java.lang.IllegalArgumentException: Unknown proxy type

2011-08-03 Thread Y2i

Just tried to migrate from 2.2 to 2.4 RC1.

First, the project didn't compile because of internal compiler errors.  All 
obsolete RF-related stuff is removed from 2.4 (good), but if the project 
uses RF there is no way to move to 2.4 without migrating from gwt to 
web.bindery.
After migrating from gwt to web.bindery the internal compiler error 
disappeared (good).
After fixing some incompatibilities the project now compiles and the 
application starts (good).
But it fails to run in exactly the same spot as when moving from 2.2 to 2.3 
without migration from gwt to web.bindery (bad).  And in 2.2 the application 
runs fine.

Here is the culprit:

interface P extends EntityProxy { ... }
interface PA extends P { ... }
interface PB extends P { ... }

interface R extends RequestContext {
  RequestLong queryCountOfP(P p);
}

When queryCountOfP() accepts an instance of PA, the onSuccess() callback is 
called fine.
When queryCountOfP() accepts an instance of PB, the failure occurs:

java.lang.IllegalArgumentException: Unknown proxy type PB

The server receives the call, the argument type of the service method is 
correct (B), but after returning to the client the following method throws 
an exception:
at 
com.google.web.bindery.requestfactory.shared.impl.AbstractRequestContext.createProxy(AbstractRequestContext.java:489)
Neither onSuccess() nor onFailure() nor onViolation() gets called.

Why does the method fails on PB but not on PA?  Is there anything wrong with 
this usage pattern?

Thanks!

Отг: Do Beanvalidation(JSR-303) and editor framework play along well ?

2011-08-03 Thread Miroslav Genov

Yeah, in 2.3 validation is a little bit broken, cause it was fully 
refactored after GWT 2.2. The things are working well in GWT 2.4-rc1 I 
think. 

DynaTableRf contains a nice validation example. To check whether JSR-303 is 
working, just check that demo project but don't forget to remove this 
validation check from PersonEditorWorkflow.java

// Check for errors
if (editorDriver.hasErrors()) {
  dialog.setText(Errors detected locally);
//  return;
}

They really like Javascript, and that gives a strong bias to their report. I 
suspect generating Javascript from something else probably feels morally wrong 
to them. Personally, I'm *much* happier writing in Java and very pleased that 
GWT allows me to create Javascript without having to write Javascript.

For enterprise use, they made no mention of any of the benefits of GWT. Like 
the tool set, being able to share code between client and server, code 
splitting, optimised Javascript, deferred binding and more.

This report presents their view, and doesn't try to be balanced or unbiased.

First, in many ways, JavaScript is more powerful and expressive than
Java, so we suspect that the generation is going in the wrong
direction.

more powerfull for that?

This critique makes no sense, as the two languages are comparable in
expressivity.  Admittedly something is lost in translating from one to
the other, and maybe that's what they want to say.

The tool support for Java is really very good. That counts for an awful lot in terms of 
helping to save developer time and be able to produce good results. Besides, what on 
earth does generation is going in the wrong direction mean? Browsers run 
javascript, so it's the end product of the compilation. Reversing the direction makes no 
sense. As long as you can express everything reasonably in Java, and you can convert that 
to javascript well (which GWT can), I don't see the problem. But then, I'm not in love 
with javascript.



Secondly, it is impossible to hide a complex abstraction
difference like that from event-driven desktop to stateless-web
without leaky abstraction headaches eventually popping up

I can't comment, I do not know the compilation process.

The JavaScript engines that GWT targets are not stateless.  There is
no such gross incompatibility between the source and target platforms.
I wonder what they were thinking?

If there are abstraction headaches within GWT, Google are doing pretty well at 
hiding them. It's not perfect (eg key mappings used in the keyUp, keyPressed 
events etc), but we're stuck with the web browser as the deployment engine and 
that limits what can be done while achieving very high browser compatibility. 
They may have a point, but is it really significant?

However, just like Michael, I'm not really sure what they were trying to say. 
Their comments here leave me feeling like they're complaining about some kind 
of perceived potential problem rather than a concrete issue.




Third, it suffers from the same shortcomings of many elaborate
frameworks, where building simple, aligned applications is quick
and easy, building more sophisticated but not supported
functionality is possible but difficult, and building the level of
sophistication required by any non-trivial application becomes
either impossible or so difficult it isn’t reasonable.

What is meant by functionality not supported?.  Program non-trivial
applications with GWT is easier than directly in javascript

GWT isn't actually a framework, it's a toolkit. But, putting that aside, I've 
built a complex application with GWT and I don't think their characterisation 
of the feasibility of doing this is at all accurate. However, things did take 
me longer when I was new to GWT (and not particularly familiar with css either 
at the time). Whether that's just the normal learning curve or something else, 
I can no longer tell.

Re: GWT CELLTABLE How to restore old value in cell if validation fails

I can restore old value in specific cell if validation fails.

Is it possible that all column values from particular row restore to

|| .||Q1||
changed to
|| 1  ||  BP   || 010  ||  3  ||  003

Is there any way to restore old object(row) values instead to clearing
cell view data for each column and redraw editable grid.

In Short revert record to old value which is selected by our checkbox
(All or selected chkbox only i.e selectionModel.isSelected(object) )

My Grid contain (2-N) column so I am asking this question ?

 Hi Vaibhav,

 You can do it like this:

 cell.clearViewData(KEY_PROVIDER.getKey(object));
 cellTable.redraw();

 Where cell is the TextEditCell that you're using for that column.

Re: Extending/embedding DialogBox

2011-08-03 Thread Wulfsberg

Aidan, that was exactly my point: You lose UIBinder control over the
caption there, forcing you to create your dialog box from a mix of
Java parameters and UIBinder XML, which grates somewhat. In my
opinion, it should be either/or, not a mix.

I can see a point for making a fairly standardized dialog (like, say,
an OK/Cancel box) a subclass, and feed all information (caption and
lead text) through Java as a single (constructor) call, but with more
complex dialogs I'd like to be able to design them - and let other
people modify them - with the UIBinder system.

It seems to me there is a bit of a mismatch in the design here.

On Aug 3, 12:24 am, Aidan O'Kelly aida...@gmail.com wrote:
 You can actually just change your UiBinder java class to inherit from

 the regular, initWidget() method of Composite.

 Your UiBinder template then just looks like this:

  I'm guessing that the you're not supposed to do this comment you're

  A PopupPanel should not generally be added to other panels; rather, it
  should be shown and hidden using the show() and hide() methods.

  Derek's approach is the only way I can think of to use g:DialogBox in a UI
  template without it being automatically added to another panel. However, I
  don't like that approach because the custom dialog box does not actually
  subclass DialogBox. This necessitates having like-named methods that proxy
  to the DialogBox returned from UiBinder, such as center() in Derek's
  example. Unlike cases where it makes sense to subclass Composite to hide the
  root widget's API, the custom dialog box really is a dialog box and should
  inherit the DialogBox API.

  What I settled on was to subclass DialogBox and use UiBinder to build the
  widget passed to DialogBox.setWidget(). My hope is that this encourages its
  use from java code instead of a UI template. In reality, my custom dialogs
  are no more opinionated about where they're used than GWT's own DialogBox
  is, which has a nice harmonious feel to it.

(widget I created myself) until generation of service return url so I
redirect the new  window to that url.
So my question how to inject a new widget into new window browser.
Note: I used JSNI  to open new window this way
win =$wnd.open = $ (url, name, );
and when service is generated i use this:wnd.location = url;

Any help would be appreciated.

});
leftSlider.addMouseMoveHandler(new MouseMoveHandler() {

@Override

leftSlider.getElement().getStyle().setLeft(event.getRelativeX(container),

rightSlider.addMouseMoveHandler(new MouseMoveHandler() {

@Override
public void onMouseMove(MouseMoveEvent event) {

rightSlider.getElement().getStyle().setLeft(event.getRelativeX(container),

}
});
}
Initially when the page renders, it is fine. When i do mouse over the slider
images,
i observe that
1) MouseMoveHandler works only with mouse movement from left to right. If a
move the mouse from right direction to left, nothing happens.
2) Also, how do i check bounds?
3) How to set the minimum and maximum value of the sliders?

 If you will use html use drag start, drag move and drag end events and do
 not capture the event, everything else is the same.
 If you wont use html5, on mouse down event do:
 Event.setCapture(leftLabel.getElement());
 And on mouse up event Event.releaseCapture(leftLabel.getElement());
 Capturing the element means that all events will be passed to that element
 till release.
 Then you need to implement the mouse move for the label:

1. Find the mouse position relative to the sliders container
(event.getRelativeX(container) and event.getRelativeY(container))
2. Calculate the current position
3. Check bounds
4. Set the position of the slider (basically set the left style to the

 do the same for the right slider, add some pretty styles and you are ready

Implementing a Calendar (Week) View with Cell Tables

2011-08-03 Thread P.G.Taboada

Hi,

did anyone try to implement a calendar with cell widgets? There are a
two google like calendar gwt widgets out there, but they offer more
than I need and they are buggy.

My old jsp/struts based solution is a simple table with lots of row-
spans. I don't need drag and drop.

The cell table is quite close to what I need, the only problem is the
data structure: the cell table works fine for row based data
structures, calendars are column based.

I could shift my data around, but I am sure if this would not really
make me happy. It would eternally feel like a workaround.
So I am thinking in using cells to render my data and use a flex table
to put things into.

Which joda time projects are you guys using? I found three projects,
not sure which one to use.

brgds,

Papick

Re: EventBus in 2.4

2011-08-03 Thread objectuser

I have been looking forward to 2.4 for the built-in validation support. 
 However, those classes still have comments with don't use this in 
production caveats.

Maybe the RC1 tag is premature then and there's going to be more work done. 
 Or maybe 2.4.0 will just introduce the validation framework in an 
experimental preview.

Any insight from anyone that's the project would be appreciated.

Re: GWT CELLTABLE How to restore old value in cell if validation fails

2011-08-03 Thread Ioan Agopian

No, I don't think that's possible.

But you can store all your edit cells in a list and clear them all at
once, like this:

// when setting up table columns add the edit cells to this list
ListEditTextCell editCells = new ArrayListEditTextCell();


// clear incorrect values for the whole row
for (EditTextCell editCell : editCells)
{
 editCell.clearViewData(KEY_PROVIDER.getKey(object));
}

cellTable.redraw();

Ioan

Re: showRelativeTo doesn't work the first time

2011-08-03 Thread Brian Reilly

I've had issues with positioning (specifically centering) when setting 
dimensions of the popup contents using CSS (width in my case, but I imagine 
hight could have similar issues). My dialog box would be positioned too far 
to the right the first time is was displayed using center(). The second and 
successive calls to center() would work properly. Especially strange is that 
the behavior was the same even when creating new instances of the dialog 
box. (My testing was in Safari)

Calling setWidth() on the dialog's widget from java instead of using CSS 
fixed it for me.

Re: MVC + Command Pattern + Code Splitting?

2011-08-03 Thread Gabriel

Check out GWTP: http://code.google.com/p/gwt-platform/

On Aug 1, 5:28 pm, gktcs tdotstew...@gmail.com wrote:
 Has anyone been able to get complete code splitting working with gwt-
 dispatch or similar command pattern implementation?

 We've got a rather large MVC-based application, and our code splitting
 is done at the Controller level.    The code splitting works great--
 neither the Controller nor the View will be loaded unless the
 associated module has been explicitly requested.  We use gwt-dispatch
 (with SecureDispatchAsync) to provide our communication with the
 server.  Everything works great with gwt-dispatch, except that *all*
 of our Request (Action) and Result objects are compiled into the
 initial download, instead of being included in the split point which
 contains the associated Controller and View.

 We're using SecureDispatchAsync in the startup module to load some
 basic startup information, but all of the other Request/Result pairs
 are isolated to their corresponding Controller.  The GWT SOYC report
 shows that all of the Request and Result objects are being included in
 the initial download.  Given the large-ish number of Action/Result
 objects we have, this is adding significant bulk to our initial
 application download size.

 I've read around and asked on the gwt-dispatch group and it seems like
 no one has had to use code splitting and the command pattern; so far,
 the only answers I've been able to find were (a) had to get rid of gwt-
 dispatch/command pattern, (b) just accept the increased size, or (c)
 it could be related to this 
 issue:http://code.google.com/p/google-web-toolkit/issues/detail?id=2374.

 Just curious as to what others are doing, or if someone has found a
 way around this problem

 Thanks

Re: showRelativeTo doesn't work the first time

2011-08-03 Thread Eric Andresen

I've also seen similar problems with showRelativeTo.  I've noticed that if I 
show a popup dialog that has dynamic sizing (i.e. the widget is a 
FlowPanel), the first time it pops up it shows as very wide and goes off the 
screen.  If I close and re-open it, the second time it correctly wraps its 
contents to the boundary of the window.  I think maybe there is a timing 
problem with the position() call inside showRelativeTo?

Re: Extending/embedding DialogBox

2011-08-03 Thread Brian Reilly

That's exactly what I do. Use of UiBinder is then simply an implementation
detail of how the UI is constructed for the custom dialog.

If you want your custom dialog to be created from UI templates, there are a
few options for initializing both a caption and a widget.

1. use a text attribute in the UI template: my:CustomDialogBox
text=Caption Text/
2. add a setCaption(String caption) method to your dialog that proxies to
setText() and use a caption attribute in the UI template:
my:CustomDialogBox caption=Caption Text/. This causes the caption to be
_optional_.
3. add a constructor, CustomDialog(String caption), annotated with
@UiConstructor and use a caption attribute in the UI
template. my:CustomDialogBox caption=Caption Text/. This causes the
caption to be _required_.

Also, while I don't think it applies to this case, check out @UiChild for
cases where you want something similar to having a custom UiBinder parser
for your
widget:
http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/uibinder/client/UiChild.html

You can actually just change your UiBinder java class to inherit from

Your UiBinder template then just looks like this:

I'm guessing that the you're not supposed to do this comment you're
referring to is this comment from the PopupPanel javadocs:

A PopupPanel should not generally be added to other panels; rather, it
should be shown and hidden using the show() and hide() methods.

Derek's approach is the only way I can think of to use g:DialogBox in a
UI
template without it being automatically added to another panel. However,
I
don't like that approach because the custom dialog box does not actually
subclass DialogBox. This necessitates having like-named methods that
proxy
to the DialogBox returned from UiBinder, such as center() in Derek's
example. Unlike cases where it makes sense to subclass Composite to hide
the
root widget's API, the custom dialog box really is a dialog box and
should
inherit the DialogBox API.

What I settled on was to subclass DialogBox and use UiBinder to build the
widget passed to DialogBox.setWidget(). My hope is that this encourages
its
use from java code instead of a UI template. In reality, my custom
dialogs
are no more opinionated about where they're used than GWT's own DialogBox
is, which has a nice harmonious feel to it.

Collection that notifies listeners of a change

2011-08-03 Thread Sébastien Tromp

Hello,

I am trying to build an implementation of the Set interface that notifies
registered handlers when a modification occurs on the Set.
First of all, has this already been done somewhere?
I couldn't find anything, so I went on to build my own. The issue I have is
that, when the Change event is fired, the handlers are not notified.

My code is as follows:

public class NotifyingSetT extends Composite implements
HasCollectionChangeHandlersT, SetT {

private final SetT wrappedSet;

public NotifyingSet() {
this.wrappedSet = new HashSetT();
}

@Override
public boolean add(final T e) {
final boolean ret = this.wrappedSet.add(e);
this.fireEvent(new CollectionChangeEventT(Operation.ADD, e));
return ret;
}

   ...
}



public interface HasCollectionChangeHandlersT {
HandlerRegistration
addCollectionChangeHandler(CollectionChangeEventHandlerT handler);
}

---

In my presenter, I do this:

// Also tried with GWT.create()
private final NotifyingSetFightRequest fightRequests
= new NotifyingSetFightRequest();

this.registerHandler(this.fightRequests
.addCollectionChangeHandler(new
CollectionChangeEventHandlerFightRequest() {
@Override
public void onCollectionChange(final FightRequest
element,
final
com.fiveorbs.client.events.CollectionChangeEventHandler.Operation operation)
{
logger.info(on collection change)
}

}));

...

fightRequests.add(someobject);


After the add, I would expect my handler to be called, but to no avail.

Would you have any idea as to what I'm doing wrong?

Thanks,
--

The JSONObject takes only JavaScriptObject as its constructor parameter. 
JavaScriptObject can be returned only by a JSNI function which I wrote:

public static native JavaScriptObject parseJson(String jsonStr) /*-{
return eval(jsonStr);
}-*/;

but when I do 

String json = {\userId\ : \123\, \sessionId\ : \456\};
JavaScriptObject javaScriptObject = parseJson(json);


I get

ERROR: Uncaught exception escaped. 
com.google.gwt.core.client.JavaScriptException: (SyntaxError): Unexpected 
token :

Re: Collection that notifies listeners of a change

2011-08-03 Thread Sébastien Tromp

After debugging, I think I found the solution to my issue. It had to do with
parameterized types, which would break the event flow.
Simply extending all classes to remove all parameterized elements did the
trick.

2011/8/3 Sébastien Tromp sebastien.tr...@gmail.com

 Hello,

 I am trying to build an implementation of the Set interface that notifies
 registered handlers when a modification occurs on the Set.
 First of all, has this already been done somewhere?
 I couldn't find anything, so I went on to build my own. The issue I have is
 that, when the Change event is fired, the handlers are not notified.

 My code is as follows:

 public class NotifyingSetT extends Composite implements
 HasCollectionChangeHandlersT, SetT {

 private final SetT wrappedSet;

 public NotifyingSet() {
 this.wrappedSet = new HashSetT();
 }

 @Override
 public boolean add(final T e) {
 final boolean ret = this.wrappedSet.add(e);
 this.fireEvent(new CollectionChangeEventT(Operation.ADD, e));
 return ret;
 }

...
 }

 

 public interface HasCollectionChangeHandlersT {
 HandlerRegistration
 addCollectionChangeHandler(CollectionChangeEventHandlerT handler);
 }

 ---

 In my presenter, I do this:

 // Also tried with GWT.create()
 private final NotifyingSetFightRequest fightRequests
 = new NotifyingSetFightRequest();

 this.registerHandler(this.fightRequests
 .addCollectionChangeHandler(new
 CollectionChangeEventHandlerFightRequest() {
 @Override
 public void onCollectionChange(final FightRequest
 element,
 final
 com.fiveorbs.client.events.CollectionChangeEventHandler.Operation operation)
 {
 logger.info(on collection change)
 }

 }));

 ...

 fightRequests.add(someobject);
 

 After the add, I would expect my handler to be called, but to no avail.

 Would you have any idea as to what I'm doing wrong?

 Thanks,
 --

It's not up to GWT, it's up to the browser to evaluate the string. Take 
a look at the source code.

Sort of.

The JSON spec indicates that you don't quote numbers, OTOH, your 
application may warrant those quotes.


Other points:
o You want to use a JavaScript Object as the destination of the parse 
object. Here I deliberately use saveEval because I trust the source of 
the string.

JSObject = JsonUtils.safeEval(source);

where JSOBject is a class that  extends JavaScriptObject and optionally 
implements an interface. Using the interface allows you to mock the JSO.


o You want to use the JSObject as the source of the associated string. 
The round trip should be idempotent.


 @Override
 public final String export() {
   return new JSONObject(this).toString();
 }

o example:
  {\activityName\:\L\, \id\:12, \predecessorList\:[11,10], 
\likely\:0, \worst\:0, \best\:0}

The problem with that is that the GWT EventBus would be compiled separate

Re: About GWT opinion in thoughtworks technology radar july 2011

2011-08-03 Thread kellizer

I agree fully with Paul's comments and I do have great respect for a number 
of the authors and have indeed heard them speak on a number 
of occasions however I do get the sense that there is an element of bias 
towards native javascript and, in my personal view, a lack of exposure to 
GWT.. 

I've been using GWT for a over 6 months now and have written a quite complex 
application that works very well and a great deal of that is to do with the 
GWT technologies- I'm not suggesting that it could not have been achieved 
with native javascript but that (for me) would have been much greater of a 
challenge than starting with GWT and I personally have not run into 
the negative points that the authors have raised.. 

Giving what I know now (after being exposed to GWT *in anger*) - I would 
still continue to utilise the GWT technology on future projects as I don't 
believe by using javascript would give me any advantages but I do believe 
that it would give me a number of disadvantages (across the complete 
development lifecycle).

Regards,

Ian.

IE8 - Not working - Mouse event for ListBox

2011-08-03 Thread Ash

Hi,

I'm using a list box which has many URLs for image. When someone move
the mouse through the drop down values, I need to show the image in an
HTML box. This works fine (MouseMove) in Firefox, but does not work in
IE8.

The below code represents the test case, and none of them gets
called / fired in IE8.

Can someone please help me to sort this out. I'm using GWT 2.0.3.



ListBox listItem = new ListBox();
listItem.addMouseMoveHandler(new HandlesAllMouseEvents() {

public void onMouseDown(MouseDownEvent event) {
Window.alert(On Mouse down...);
}

public void onMouseUp(MouseUpEvent event) {
Window.alert(On mouse up...);
}

public void onMouseMove(MouseMoveEvent event) {
Window.alert(On mouse move...);
}

public void onMouseOut(MouseOutEvent event) {
Window.alert(On mouse out...);
}

public void onMouseOver(MouseOverEvent event) {
Window.alert(on mouse over...);
}

public void onMouseWheel(MouseWheelEvent event) {
Window.alert(on mouse wheeel);
}
});

Thanks,
-ash

Detecting a checkbox click

2011-08-03 Thread Roger Studner

I'm trying to detect a checkbox selection click so I can do some other work 
(enable a button/change some css.. trivial stuff)

I tried GWTQuery, which fails (I can bind a click handler to every checkbox.. 
but after 1 click, CellTable appears to remove my bindings hah)

I've tried overriding piles of methods.. setting handleSelection to true and 
overriding methods.. and in the end.. I can't seem to solve this trivial use 
case.

i'm doing:

table.setSelectionModel(selectionModel, DefaultSelectionEventManager.MyObject 
createCheckBoxManager());
(selection Model is single selection)

I've seen posts on stack overflow about a custom checkbox manager, but none of 
the code compiles/works (even if I try to tweak it to get it compilable)

I also tried using column.setFieldUpdater (how i've done click handler on other 
columns) and that as well fails to work.

I assume this is a solved problem, but google searching has failed me :)

Anyone :)?

Thanks in advance,
Roger

 For that you need to use a GWT FormPanel and Apche commons ServletFileUpload
 to get the file item then do the usual java io process to convert to a byte

 If this is not what you looking for , please elaborate on the question.

RPC and server side classes

2011-08-03 Thread Mike Dee

I'm updating an existing web app to use GWT and encountering a problem
on server side. A goal is to reuse the server side data classes,
which are stored in a separate Eclipse project.

I have two projects: OldProject, which has old data classes (as POJOs)
and NewUiProject, which is GWT.

If I put the OldProject POJOs in the NewUiProject, all is fine. Of
course the POJOs don't fall under the shared directory, so I created
a .gwt.xml file and inherited that into the NewUiProject .gwt.xml.

If the OldProject POJOs are left in their project and NewUiProject
inherits the .gwt.xml from OldProject a runtime error occurs.

[ERROR] javax.servlet.ServletContext log: Exception while dispatching

at javax.servlet.http.HttpServlet.service(HttpServlet.java:637)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

It looks like FooDataClass is simply not found on the server side and
I can't figure out why. I am using Eclipse and NewUiProject has a
project reference to OldProject and also includes OldProject in the
Java Build Path Projects. If there were a project with references
across projects I don't think the project would compile. I also tried
packaging a JAR from OldProject and including it in NewUiProject, but
that makes no difference.

I don't think this is a case of not inheriting classes so that GWT
knows to compile them in the client side. That would produce an error
when starting up the client and an error message about not being able
to find the source code for the data classes. I'm mot seeing that
error. The UI comes up and the error is thrown when interacting with
the UI in such a way as to cause an RPC.

Any ideas?

Thanks,
Mike

Re: How to add hover on CellList

sink the mouseover event on your cell and add a handler for mouseover and

which are stored in a separate Eclipse project.

I have two projects: OldProject, which has old data classes (as POJOs)
and NewUiProject, which is GWT.

If the OldProject POJOs are left in their project and NewUiProject
inherits the .gwt.xml from OldProject a runtime error occurs.

Re: Отг: Do Beanvalidation(JSR-303) and editor framework play along well ?

2011-08-03 Thread Karthik Reddy

Thanks for the helpful info.

I will go ahead and build the DynatableRF sample in 2.4 and try it out . 
Hopefully, in 2.4's  DynatableRF,  I could witness the fruits of the 
 marriage between client-side validation and editor framework.

Did you happen to follow any sort of guide to getting validation working in 
2.4 RC1?  I failed in my attempt.

[RPC problem] Caused by: java.lang.OutOfMemoryError: Java heap space

2011-08-03 Thread Rafael

Hello everyone!

I have a very disturbing problem (disturbing to me at least), the
exception mentioned in the title of this post occurs on the server
side but after the RPC executes.

I'll explain briefly, i have a DAO interface and a DAO implementation,
and besides, i have the two interfaces and class necessary to
implement a GWT RPC, i use the latter to define a way to call the
methods of the DAO from the client via a asynchronous call.

When i try to invoke the GWT RPC, the method in the DAO executes
without incident but before the result can be returned to the client
the exception takes place.

I am starting tomcat with the -Xms1024M flag in order to increase the
heap space but i guess there is some very unefficient memory handling
somewhere in there (in my app, not in tomcat nor in GWT) but i need to
know where before i can fix it... has this happened to anyone? my
guess is that the memmory suffices for handling the RPC but not for
serializing...

anyway, i decided to seek your advice... thanks in advance!

Rafael

Here is the root cause if i am not mistaken:

Re: RPC and server side classes

2011-08-03 Thread Mike Dee

Juan, I thought you may have found the problem. There was a static
variable, the old:

static final long serialVersionUID = -1L;

I removed it, but that didn't make a difference.

Could it be that the data classes from the OldProject are really not
being picked up in NewUiProject? I tried doing a GWTCompile and
looking at the output. I don't see classes from OldProject in the WAR
for NewUiProject...even when I include the OldProject.jar! But, maybe
I don't understand enough about how GWT works?

so perhaps you have a dependency or is not serializable or instanciable in
runtime.

Is serializable? have final fields? have a default constructor?

I added a .gwt.xml file to the OldProject and inherited it from

I'm updating an existing web app to use GWT and encountering a

on server side. A goal is to reuse the server side data classes,
which are stored in a separate Eclipse project.

I have two projects: OldProject, which has old data classes (as
POJOs)
and NewUiProject, which is GWT.

If I put the OldProject POJOs in the NewUiProject, all is fine. Of
course the POJOs don't fall under the shared directory, so I
created
a .gwt.xml file and inherited that into the NewUiProject .gwt.xml.

If the OldProject POJOs are left in their project and NewUiProject
inherits the .gwt.xml from OldProject a runtime error occurs.

at
javax.servlet.http.HttpServlet.service(HttpServlet.java:637)
at
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

It looks like FooDataClass is simply not found on the server side
and
I can't figure out why. I am using Eclipse and NewUiProject has a
project reference to OldProject and also includes OldProject in the
Java Build Path Projects. If there were a project with references
across projects I don't think the project would compile. I also
tried
packaging a JAR from OldProject and including it in NewUiProject,
but
that makes no difference.

I don't think this is a case of not inheriting classes so that GWT
knows to compile them in the client side. That would produce an
error
when starting up the client and an error message about not being
able
to find the source code for the data classes. I'm mot seeing that
error. The UI comes up and the error is thrown when interacting
with
the UI in such a way as to cause an RPC.

Any ideas?

Thanks,
Mike
