Hi, I am trying to open a form for a field with "when_button_pressed' trigger from an existing form (say form_abc).
I don't want to pass any new parameters to the called form(say form_xyz).

The called form form_xyz is a tree structure.

When I select any child node of form_xyz i.e when mouse double clicked on any child node,that node value should become the value of the field of the calling form form_abc i.e I want to pass a value from the called form form_xyz to the calling form form_abc and display it in the field.


Please help.
I am stuck in it.
