Unfortunately I can't send you the workflow because I am using the unit 
testing version of the taverna workbench. Additionally, the plugin I am 
using is currently under development and not available online. Can it be 
that the unit test version hasn't got a validation report tab?

Yes, taverna tells me that the behaviour is unpredictable/invalid for 
the altered and the following service.

The ports of the service with the dot product are of mixed depth.  Two 
have depth 1 and one has depth 0.
