Hi,
first, thanks for your suggestions, I really appreciate your help.
Sorry that it took so long trying out most of the stuff:
> Did you ensure that you
> 1) set all the Ids of your programmatically created components
I did not, but now I am setting all IDs - eventhough it did not help.
> 2) have a setPanelGrid (used for the binding after page reload i think,

Yeah, got that before
> 3) set all required properties for corresponding tags (that is if tag

> in your code)
Uh-oh. That's a bit hard - how do I know which property really is required?
I thought that when it's required and missing, I would get a "method not
found" exception...
> 4) it still fails with only 1 binding, and no nested panelGrid.
I've tried whithout the nested panelGrid, did not help either. I wasn't
able to strip it down to one binding only and still perform something
usefull. What did you wanted to test in that case?
CU,
Uli
