Having an issue with an expression that always returns null. Here is my expression:
if (target.terminal_id == null && source.terminal_id_alt != null)
I'm registering target, source and dc and my ExpressionType is set to StatementList; although I've tried all them with the same results. When I call Eval(), my GetTerminalIDByTerminalAltId method is called and the parameter value is passed and that method returns
the result. However, the result (string) is never passed through Eval; all I get is a null. I gotta be missing something; any ideas?
Thanks in advance!
