Jester,
this question is a little off-topic, but on my mind none the less... Where do
you put this
code:
> prefsWindow = PopUpManager.createPopUp(this, PrefsWindow, true);
> prefsWindow.setFormData(ModelLocator.prefsObject);
I naturally want to put this in my PrefsWindowViewHelper, but it doesn't seem
to work
when there. What I find is happening is every view that's a titlewindow ends up
adding
code to my applicationViewHelper. this "smells" i think.
