Hi,

The problem is that EditPage when deserialized creates a new copy of
MyPanel instance and its bChanged member field.
The best/simplest way is to use a Panel as ModalWindow content instead of a
Page.
Another way to share bChanged between the pages is to store it in the
session (i.e. MySession#bChanged).
Yet another way is to get a reference to bChanged thru the first page:
- pass a PageReference of page1 to editpage and later use it:
pageRef.getPage().setChanged(true)
