Hello, I have noticed one problem and cannot say how is that happening.
I have a page, which contains form with two DropDowns with AJAX behaviours
on them.
When I select something from first dropdown, AJAX sets some values on other
To get a value from dropDown I use CompoundPropertyModel, and everything
works fine.
But when I open that page in another tab (using Firefox), and select
something from first dropdown, NullPointer exception appears and as I
debugged it seems that my CompoundPropertyModel is null.

How is that happens and how to get rid of it?
