Hmm. I am using Myfaces 1.2.9 and Richfaces 3.3.3, so it's possible
that there's something different about it under Myfaces 2.0.
Under my environment, using the following insures that messages are
always rendered for ajax requests. But rendering the messages isn't
really your problem -- it's that the values aren't considered valid
for your input.
<a4j:outputPanel ajaxRendered="true">
<t:messages
globalOnly="true"
showDetail="true" />
<t:messages
globalOnly="false"
showDetail="true" />
</a4j:outputPanel>
I just noticed that you don't have a [value="#{}"] tag for your
<h:selectManyListbox>. Could this be the problem?
