default behaviour until 1.6.1 was that validation errors prevented a tab change. since 1.6.2 it is just the other way round and validation errors do allow tab changes. seems there's a regression since 1.6.2. However an additional attribute would solve the issue for both cases.

After some consideration it seems that the expected behavior in this case would be that the tab would not switch if a component on the form was in an invalid state. This would be consistent with any other component that could fire an action event (button).

However, in order to provide more flexibility to component users it would also be a good idea to add support for both the 'immediate' and 'partialSubmit' attributes to the panelTabSet component.

Developers could override the default behavior via 'immediate=true' if desired, thus having the panels switch regardless of the state of the components within them.

Setting 'partialSubmit=false' would allow the panelTabSet to enforce the 'required=true' attributes on any input components on the visible tab (or in the form, for that matter).

Does this seem reasonable?

Need this applied to the icefaces-1.7 branch for 1.7.1 also.

branch 1.7 revision 16680

Reverted a change I'd made, back to Adnan's commit, to fix a regression.
