Calling ITS from iframes

Question

Hi,
I'm trying to call an ITS service towards ISU from within
a nested iframe:
the application is build in a doublebuffered view,
in the iframe i load a main header that is used throughout
the entire session, below there is an iframe that contains
the changing views depending on the actions taken.
In that iframe i try to link a button to the ITS, but the
problem is that i receive a javascript error 'invalid pointer'
when i put that same link outside the iframe it works fine.
Is there a way to work around the nested iframe?
my sapevent is coded like this:
w_event = model->get_sapevent_string(
  action  = 'BOR'
  name    = zappl_model=>co_objtype_cfs_creditrating
  system  = 'isu'
  key     = model->partner
  method  = 'Display' ).
  concatenate
  'javascript:parent.subFrame6435645.document.forms[0].action='
  '''' w_event '''' ';'
  into w_event.
  concatenate w_event
  'parent.subFrame6435645.document.forms[0].submit();' into w_event.

Got the solution:
In the specific services there is an option gui-configuration disconnectonclose which must be 0.
