Problem with commandButton and required form fields
Hi all,
I am having a problem with a form in an application I am working on and was
wondering if anyone else had the problem. I have a large form that is part
of a tabbed pane, where there are many form fields that are required
(required="true"). Within this form I have a place where a user can enter
information in 2 of the form fields and click an "Add" button which adds
values from the 2 form fields to a backing bean. The problem lies in that
if any of the other fields on the form are required, this "add" function
will fail due to failed form validations. I cannot make the "Add" button
immediate="true" because this bypasses the apply request values phase if I
understand correctly. Any suggestions would be appreciated. Thanks in
advance. Hope this makes sense.

Just came across something that might make this a lot easier:
===============
Components that implement EditableValueHolder (such as UIInput), and
whose immediate property is set to true, will cause the conversion and
validation processing (including the potential to fire ValueChangeEvent events)
that normally happens during Process Validations phase to occur during Apply
Request Values phase instead.

Yeah, it looks like the two options are:
1) parse out the form values yourself
2) create an alternate lifecycle that conditionally skips the validation phase.
Have you found any shortcuts for pulling in and populating the form
values? Seems like a lot of duplication of JSF functionality.

I figured out a way to get this to work. I have the immediate value for the
button set to immediate="true" and then I created an actionListener that
populates the backing bean with the values manually. Hope this helps.

I don't have any answers yet, but I'm having the same issue.
