Hello Sean,

I don't think this is the problem now.
What you described was a previous bug, but now the pannelTab decodes only the right components.
So, the checkboxes from another tab aren't decoded & reset.

Furthermore, if this were the case, the checkbox from tab 1 would reset too, and it doesn't.
I'll try to include h:inputText in the dataTable to see if we have the same behaviour, or if it's related to the checkBox.

Sylvain.

Sylvain,

I figured out your problem.  Its a combination of the checkbox and the
panel tab together.  The datatable is not the problem.

The default behavior for the checkbox is to *reset* the value of the
checkbox during the decode phase.  (See
HtmlRendererUtils:decodeUISelectBoolean.)  This makes sense because
HTML standard will not submit "false" values for unchecked checkboxes.
 So unless the checkbox is disabled, faces assumes that it is
unchecked and rechecks it every time its posted (as long as the value
is submitted as true.)  IMO this is desirable (and I believe probably
part of the spec.)

As I mentioned your example works fine if you press the "common submit
button"  on the tab (checkbox with true stays checked after the post.)
 The problem starts once you click on another tab.  I didn't have time
to investigate the specifics but I think I have discovered the basic
problem.

You checkbox value does not get posted when you click on one of the
other tabs.  Even if it does get posted, it is posted to a request
scope bean.  Say you go from tab 3 to tab 1.  On tab 1 your sample
checkboxes are not rendered so when you click back to tab 3, you are
*not* posting any values for them.  Because the decode is resetting
the values, you end up with "false" for all of your checkboxes.

The other checkboxes are ok because they are common to all 3 tabs so
they constantly get posted.

That's the source of the problem.  I will try and learn more about
panelTab so I can help with the fix but there are some complicated
choices to make.  I suppose for now you could have the checkboxes be
hidden on the tabs where they shouldn't be displayed so that they are
common to all tabs.

HTH,

sean
