Multi-form applications

Question

I have a created a multi-form application where i have a calling form which calls another form. The user could commit changes in the called form and return to the calling form and either have changes in that form committed or rolled back. However, a commit in the called form SHOULD NOT commit any changes in the calling form. All this works fine.
I have implemented this using "autonomous transaction". I am using the call_form --> open_form sequence for this purpose. i.e there is a call to a dummy form using call_form and this dummy form calls the other form using open_form call. Now, the problem that i have is that, at times the called form gets hidden behind the calling form and what is visible to the user is the calling form - with no access to any items on the form as this form is now NOT the active form in the application. This problem, though not reproducible has occurred many times. I do not have a solution to this. Any suggestions/pointers/soultions most welcome.
Thanks in advance..

What are OPEN_FORM,CALL_FORM,NEW_FORM? diff?
CALL_FORM : It calls the other form. but parent remains active, when called form completes the operation , it releases lock and control goes back to the calling form.
When you call a form, Oracle Forms issues a savepoint for the called form. If the CLEAR_FORM function causes a rollback when the called form is current, Oracle Forms rolls back uncommitted changes to this savepoint.
OPEN_FORM : When you call a form, Oracle Forms issues a savepoint for the called form. If the CLEAR_FORM function causes a rollback when the called form is current, Oracle Forms rolls back uncommitted changes to this savepoint.
NEW_FORM : Exits the current form and enters the indicated form. The calling form is terminated as the parent form. If the calling form had been called by a higher form, Oracle Forms keeps the higher call active and treats it as a call to the new form. Oracle Forms releases memory (such as database cursors) that the terminated form was using.
Oracle Forms runs the new form with the same Runform options as the parent form. If the parent form was a called form, Oracle Forms runs the new form with the same options as the parent form.
Call_form.
BEGIN
CALL_FORM('FORM2',
NO_HIDE,
DO_REPLACE, -- replace menu
NO_QUERY_ONLY,
SHARE_LIBRARY_DATA);
END;
Syntax
OPEN_FORM(form_name);
OPEN_FORM(form_name,activate_mode);
OPEN_FORM(form_name,activate_mode,session_mode);
OPEN_FORM(form_name,activate_mode,session_mode,
paramlist_name);
OPEN_FORM(form_name,activate_mode,session_mode,
paramlist_id);
