We use a webdynpro component as pop up .Basically when user clicks on a link to action in a table UI we call this pop up.
On this popup we add file to a business object and what we wanted to do was when file is attached using add button and pop up is closed we want to update the link to action with number of files attached in popup.
Example: Initial link to action Add
After adding link to action Add(1).
We dont want to modify the component we call as pop up and so i was thinking to subscribe the close button to update the link to action?
Please let me know if this approach is good enough and if anyone has example to subscribe to close button or any help on this?
