Sorry, I was talking about Thomas Broyer solution #1.
Your code (pastebin) is what I was already doing.
BTW this is the .java:
public final class AboutDialogDisplay {
@Inject
private AboutDialogDisplay() {
uiBinder.createAndBindUi(this);
}
@UiFactory
DialogBox thatsJustMe() {
return this;
}
}
And this is the .ui.xml:
<g:DialogBox animationEnabled="true" glassEnabled="true" modal="true">
......
</g:DialogBox>
Thanks
Stefano
