Hi,
I do get a response, the page is rendered again with the same combo, any values
I selected are resetted to the first entry in the list.
I tried setting an initial value, but this doesn't make any difference.
I've added a Phase Listener and debugged through it to see in which order the
phases occur:
1. RESTORE_VIEW
2. APPLY_REQUEST_VALUES
3. RENDER_RESPONSE
I don't know how that is possible, I would have expected a "Process Validation"
phase after which me listener should be called.
Any ideas ?
Thanks,
Peter
