I didn’t think of the namespaces (although this explains why further testcases failed even after manually correcting the SOAP URL in Analyzer).
I’d nevertheless vote for a change with the next major release 😉 Due to the simplified component diagram introduction, existing projects / WSDLs need to be “migrated” anyway.
Currently the modeling guideline is:
Once you defined a SOAP Service, never ever again modify any package name that contains data structures.
I fear this does not promote agility 😉
