<P><FONT size=2>Hey Mike,<BR><BR>Alon was having a moan about this back in November (thread "Specifying<BR>Interface as Importing parameter") and as far as I know this is still<BR>not possible in 700.<BR><BR>Actually it looks like Alon asked Jocelyn about it on 21/6 in the<BR>thread "Presentation on Classy Workflows / BOR vs ABAP OO" and we're<BR>still waiting for Jocelyn's reply.<BR><BR>Jocelyn? Any words of wisdom?<BR><BR>Cheers,<BR>Gavin<BR><BR>2007/6/26, Mike Pokraka <asap@workflowconnections.com>:<BR>> Hi Workflowers,<BR>><BR>> A very technical question: Has anyone tried to use some sort of<BR>> polymorphism with ABAP classes in workflow?<BR>><BR>> I am working on 620 at the moment and the trouble is that the WF builder<BR>> doesn't let you specify an interface as a class container element type. I<BR>> have even tried to get it to work via inheritance (i.e. binding a subtype<BR>> to it's supertype and vice versa) and having spent most of a day on it<BR>> have had no success whatsoever. It seems that the class you define is the<BR>> class you're stuck with thoughout the WF.<BR>><BR>> This is rather annoying and negates one of the more useful benefits of<BR>> using classes. Even though I am sitting on a 620 system, I would also be<BR>> interested in any experience on NW04/s because it would be handy to know<BR>> how things work and which direction things will go as we also have upgrade<BR>> plans around the corner.<BR>><BR>> Any input appreciated.<BR>> Cheers,<BR>> Mike<BR>><BR>><BR>> _______________________________________________<BR>> SAP-WUG mailing list<BR>> SAP-WUG@mit.edu<BR>> <A href="http://mailman.mit.edu/mailman/listinfo/sap-wug">http://mailman.mit.edu/mailman/listinfo/sap-wug</A><BR>><BR>_______________________________________________<BR>SAP-WUG mailing list<BR>SAP-WUG@mit.edu<BR><A href="http://mailman.mit.edu/mailman/listinfo/sap-wug">http://mailman.mit.edu/mailman/listinfo/sap-wug</A><BR></FONT></P></DIV></BODY></HTML>
