I'm getting the same error and similar behavior using Soap UI 4.5 Build Date 2012/03/26 16:10. (Win32)
Under 4.0.1:
I have a request that works against 4 different svc endpoints.
Under 4.5:
The exact same project/request works for 2 out of the 4 svc endpoints. The other 2 come up with the error noted in this thread.
For now- I will continue to use v4.01 as primary but continue to play around with v4.5. Also I assume the project xmls are seamlessly compatible between the 2 versions?
Is there a work around for this until the issue/ bug is resolved?
Thanks in advance.
