New Revision: 19465
Trac: http://svn.gnucash.org/trac/changeset/19465

Modified:
   gnucash/trunk/src/import-export/aqbanking/gnc-ab-utils.c
Log:
Add aqbanking5 extensions of GWEN_GUI object.

We need to locally store a reference to that particular GWEN_GUI
object that was used in Extend because we have more than one such
object in use inside gnucash (currently). If accidentally the wrong
one would be used in Unextend, a crash occurs.
