panel stack question

[Werner Punz <we...@gmx.at>]

Hi, I have a problem which I don´t know exactly how to solve...

As far as I can understand, the panel stack control relies on an 
embedded form in which the drop down box/selectOneMenu is placed.

I now have following problem.
I have a form and in the center of the form is a selectOne Menu. The 
selectOne Menu is a chooser which then basically enables a different 
subpanel below it so far so good, it basically works the demo way.
But I now face the problem, that the selectOne menu is basically inside 
a bigger form which also contains the subPanel.
And here the problems start, the subPanel seems to refuse to swith to a 
different panelStack element as soon as the whole thing is activated.

Did anybody solve this problem already or do I miss here something.
(in the demo the subpanel panel stack was outside of the form)

Ok I got it working, but I found a weird inconsistency which might
be rather problematic...
First of all, you can switch panels of a stack panel inside of a form,
that works. But the main problem is, once you have validators somewhere 
in the form, and they trigger following happens.
The selectOne menu is selected but the stack panel switching is 
prevented due to the error (dunno if this only happens if the error is 
within the panel, but I doubt it).

That basically is a huge problem user interfacewise, because you can see 
a switched panel on the selectOne menu, but the panel stays the same in 
the stack panel part of the page. The proper behavior would be, either 
to switch the panel, no matter what, or to reset the selectOne to the 
old value.
I dont know how to fix this (probably has to be fixed in the core java 
code). Guess I leave this open for discussion here.
