I can confirm that it stoped working, but it depends on the webform configuration, just macth of the situations here
WebForm (file)
Tab1 (calendars, lookups as popups)
Tab2(Lists aslo extra save/cancel button)
Tab3(embeded NetwebForm memory type) - I have problem reading values from this tab containing more tabs and checkboxes.
Tab4(embeded NetBrowse )
Save/cancel
Now
mowing the chekcboxes from Tab3 to Tab2 because then works.
To produce example- it is too complicated to do something like this.
