Hi,
Is there a justification why the broadcast method of the
HtmlPanelTabbedPane calls getFacesContext().renderResponse(), so the
model doesn't get updated? I mean, how can I preserve data from tab
changing?
Some time ago someone proposed to extend the component commenting that
line and also the subsequent call to super.broadcast()... Does it make
sense? Why can't the change of a tab update the model? Is it something
that I'm misunderstanding?
Thanks for your support ;-)
The tabbed pane effectively is like a single form with multiple "pages"
within it. The fact that you are changing page doesn't mean you are
actually *processing* the form, you're just revealing a different part
of the form to the user.
The data entered by the user isn't lost, it just remains in the
component rather than being pushed into the model until some button or
link that isn't an "immediate" control is used.
If the model is updated, then the validators are run first, and that
means that you can't change tabs if any field on the current tab doesn't
pass validation. This is why the "immediate" flag exists, and why the
tab is calling renderResponse - to allow changes to a page without
generating error messages for invalid input.
It sounds to me like you want something different: a separate form per
tab. That can probably be done by building the "tabs" as separate pages
that each include an identical header bar across the top with the tabs
in it.
