Tabbed form no submit disable tab

[brk11]

I have a tabbed form with two tabs, one of them disabled. How can I submit the form without the fields inside the disbled tab?

[brk11]

I know the solution: deferredRender: true!

[Animal]

Except if you've visited that tab, and it has been rendered!

Think more.

[brk11]

Yes, it's true! I'm at this point now... Any idea?

[Animal]

You will have to disable all child items of the Tab.

See Container.findBy

I have to disable the second tab if I change something of the form in the first tag... Is there any event in the form which is fired when a item in the form is changed?

[Animal]

Like an input Field?

[brk11]

Yes.

[Animal]

They have a change event as you can see.

[brk11]

Yes, I know... Are you telling me I have to define the listener for every field in the form? This could be a solution (what I knew, already), but I would like to have a solution at form level, which is what I'm asking.
