Hi!
Sorry, I cound not find out the solution so I've put together a demo
application and attached it.
It was cut-pasted from standard wicket examples. Namely the frames and the
ajax tree example.
Demonstrates the frame "proliferation" and intended parameter passing
between frames that simply does not seems to work for me.
Please try it.
If you click on links that start with "1:test 1." then page 1 is displayed
otherwise page 2.
Page 2 also expects a paramter that is the text of selected node. It tries
to simply display that text but unfortunately every time the default
constructor is called.
Thanks for your help.
Rgds,
Kone
