Re: RequestFactory & JPA: Does the table has to has a field called Version?
Hi David, When I´m trying to use your objectifyDao from the list widget project, Eclipse warns me already for an unsafe type cast in this code: clazz = (Class) ((ParameterizedType) getClass() .getGenericSuperclass()).getActualTypeArguments()[0]; When trying to run my application I get the following error: [ERROR] Unexpected error java.lang.ClassCastException: java.lang.Class cannot be cast to java.lang.reflect.ParameterizedType at apps.youngster.mole.server.service.ObjectifyDao.(ObjectifyDao.java:49) Do you have any idea what can cause this? I can´t find any obvious difference with your code... Thanks! -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

DialogBox looking very weird
Hi,
I would like to use a DialogBox in my application but somehow it looks
very very weird.
See screenshot: http://ScrnSht.com/dykpnl
The code is fairly straightforward:
public void onModuleLoad() {
DialogBox x = new DialogBox();
Button k = new Button("bla");
x.add(k);
x.setWidth("200px");
x.setHeight("200px");
RootLayoutPanel.get().add(x);
x.center();
I checked that standard.css is loaded and the images are available in
gwt/standard/images.
Anyone an idea what's wrong?
Thanks!

Different solution for deprecated event.getTarget()?
I can't find out how to replace the deprecated event.getTarget().
I have the following code:
@Override
public void onBrowserEvent(Event event) {
Element target = event.getTarget();
if (DOM.eventGetType(event) == Event.ONCLICK) {
for (Widget widget : widgets) {
if (widget.getElement() == target) {
Now event.getTarget says: Deprecated. use NativeEvent.getEventTarget()
instead.
Can anyone tell me how test on which widget was clicked, using
NativeEvent.getEventTarget() ??
And another question: why should I use onBrowserEvent for a Composite?
Is it not better/easier to implement HasClickHandlers? Which one
should be used when?
Thanks!

How to use RestyGWT or external module in general in new (eclipse) project?
Hi, I found a module that sounds exactly what i'm looking for but i am kind of a novice and don't know how to set it up to can use it. I'm using Eclipse with the GWT plugin. I'm talking about RestyGWT, a module that should make it possible to use REST services with the power of RPC in GWT. See: http://github.com/chirino/resty-gwt and http://github.com/chirino/resty-gwt. I really searched the net but can't find anything that helps me. I tried adding libraries, paths external sources etc. etc. etc. but nothing works. I pasted all files in my own project but then it tells me that javax.ws.* cannot be resolved. Can someone please help me with a clear description of how to get this to work in a new project (preferably in Eclipse)?
