Trigger button in main BSP from embedded (in iFrame) BSP

Hi all,

We've a BSP application where one BSP is embedded (in an iFrame) in another BSP.

Main BSP: Button "Back"

Embedded BSP: Buttons "Approve", "Reject".

What we would like to do:

If we approve or reject the content of the embedded BSP, we would like to trigger automatically the "Back" button of the main BSP.

Is this possible?

Regards,

Hans
