Hi
I've been working with JSF & IceFaces, but rather new to MyFaces + Trinidad.
And I'm facing a problem with autoSubmit.
Basically, I have two selectOneChoice elements (project and subproject), and
the second should be disabled until the first one has been selected. In the
same form, I also have a few other fields that are marked as required and need
some further validation.
The problem I have is the following: when I select an item in the first
selectOneChoice, the second becomes enabled. So far so good... So I fill in the
other fields and click the 'add' button. The problem is that the selected value
in the second selectOneChoice (#{entryBean.currentLine.subProjectId}) does not
get pushed to the backing bean, while the two others are. I can see that when
the addAction method is fired; only projectId and activityId return the right
value, subprojectid is always 0.
The first selectOneChoice is marked as immediate to bypass the validation
controls. I have also attached a valueChangeListener (projectChangeListener) to
it so that the value gets stored in the backing bean (btw, why isn't that done
automatically?)
Am I doing something wrong or is this a know issue? I don't think my case is
really unusual...
Thanks a lot for your help

currentLine.setProjectId((Long) event.getNewValue());
