Using separate_frame=true and trying to close the applet window after...

Question

We are using separate_frame=true and trying to close the applet window (the one with the large gray box) after using the following post-form trigger:
if :system.last_form = 0 then     
     message('Please wait while Forms closes - '||:system.last_form);     
     web.show_document('/forms/html/close.htm','_self');     
end if;
This works fine for the first form we open, but if that same form using Open_Form to open a child form we have a problem. When the child form is closed the user is returned to the parent calling form (which is expected), but then when the parent form is closed the separate applet window fails to close. Any suggestions?

Answer 1

I guess you mis-interpreted the value of :SYSTEM.LAST_FORM. From the online-help:
SYSTEM.LAST_FORM represents the form document ID of the previous form in a multi-form application, where multiple forms have been invoked using OPEN_FORM.So LAST_FORM shows always the ID of the last activated form, and this will never be 0 if you issued one OPEN_FORM in your application.
