Transform connections   

Hi,

I'm using MTF to transform a WBM (websphere business modeler) process model to 

another process model we've defined. There is no problem regarding the nodes, 

but I've a problem about the connections.



In WBM process model, the Connection class only records the name of source node 

and target node, but in our model Link records the source object and target object, 

so how should I write the rule for WBM Connection?



I've tried following rule which doesn't work (reports "Constraint connection2Link 

violated when target model does not exist):



relate connection2Link(wbm:Connection conn, erm:ProcessLink link)

	when equals (conn.source.node, link.sourceElement.label) 

		& equals (conn.target.node, link.targetElement.label){}



Can you shed some light on this, thanks in advance!



Regards,

Hao
