IndexOutOfBoundsException RPC Exception
John
I have a web project that is now being built using GWT 1.5.3. The
project has been in development for a few months now and just this
morning started throwing this exception - though I don't recall any
changes that were introduced when the exception started appearing:
13:17:06,752 ERROR [[/admin]] Exception while dispatching incoming RPC call

The section of code where this is occurring is in the onModuleLoad of
the app, when I add a Composite-derived object to a VerticalPanel. I
know it's this spot as I've added Window.alerts to trace it.
I'm just curious if anyone has any suggestions on how I can troubleshoot
this? I've tried rebuilding, redeploying and clearing the browser cache.
Just for completeness, here is the code I am using that throws the
exception:
private LoginComposite login = new LoginComposite();
private HorizontalPanel page = new HorizontalPanel();
private VerticalPanel view = new VerticalPanel();
public void onModuleLoad() {
// Do some set up stuff...
page.setWidth("100%");
page.setSpacing(10);
page.setHorizontalAlignment(HasHorizontalAlignment.ALIGN_CENTER);
view.setWidth("100%");
view.setHorizontalAlignment(HasHorizontalAlignment.ALIGN_CENTER);
view.add(login); // Exception is thrown here...
// view panel is added to a FlexTable inside createLayout()
page.add(createLayout());
RootPanel.get().add(page);
}
I'm certainly not suggesting that the VerticalPanel object is buggy, but
would like to know what types of errors cause this exception. Thanks
for any, and all, suggestions.
John
