That doesn't work neither, because the selectOneChoice boxes are created by an
<tr:iterator> and they are all on required=true. So when I set
immediate="true", the following selectOneChoice components will be validated
since they are all on required=true and immediate=true.
I solved that problem with the following trick, since I don't need any
validation at that point:
Iterator<?> messageIter =
FacesContext.getCurrentInstance().getMessages();
while(messageIter.hasNext()) {
messageIter.next();
messageIter.remove();
}
I do that at the end of my ValueChangeListener, when everything went fine.
But thank you anyway for your hint.
Best Regards,
Andreas

Use immediate="true"
