Subject Re: Dynamically adding components to a boxpane and ID already used error

Yes, the first time you call getWindow() in your code, you are not
qualifying it, so I think you are actually asking for the parent Window of
the ProductIntroUI instance.  At the time when initialize() is executed, the
BXML has been loaded, but not yet added to a parent Container.
See the Bindable section here.

Adding the getWindow() call into the anonymous ButtonPressListener method
should solve your problems, but I would qualify it so rather than just
Window w = getWindow();
I would do
Window w = arg0.getWindow();
using the supplied reference to the Button whose 'press event' you are
listening for.
Then the resulting Window should be the first ancestor Window of the Button
which is pressed.

One work around (if you ever need it) might be to add the
ButtonPressListener to your PushButtons when the Window is opened.  At that
time the Window would be a descendant of the Display.  You would do this
with the windowOpened() method of a WindowStateListener.  An obvious problem
with this is that a Window might be opened many times, so you would need to
ensure that you do not add multiple Listeners.
