Hi Rob.
The first step in the sub-workflow is executed successful. It searches for the approver.
The approver is used in the next step(expression). In the control tab of the User Decision Activity I specify my own task with the following binding from and to task:
X     >     &EXTENDED&
&SUNDRYINVOICE&     >     &SUNDRYINVOICE&
&DETAILSBYCC&     >     &DETAILSBYCC&
&SUNDRYINVOICE.DOCIMAGE&     >     &IMAGE&
&SUNDRYINVOICE.SOFMIMAGE&     >     &SOFMIMAGE&     
My task uses object type Decision method Process.
Kind regards
