Hi,
you don't need to modify the other pages. You could create an extended
TabPage that fires "startEdit" and "stopEdit" events as the user
interacts with it. An (also extended) TabPage could listen for these
events and disable/enable the tab controls accordingly. The only caveat
here is that you have to manipulate each button individually, i.e.:
this.getChildControl("bar").getChildren().forEach(function(button) {
button.setEnabled(false);
});
(where this is the TabView).
Regards,
Daniel
