[kepler-users] Problems with Actor - WebService With ComplexTypes

[Luis Assunção]

Hi Daniel

After more work around I think the problem happen when the input port of the
Actor is a ComplexType? 
Probably the following exception give you more exact information!
See also the attach xml file from new workflow around the same web service.

Regards
Luis

Hi Daniel

See attach the xml file from workflow.
The Web Service is running on a local machine in ASP .NET Web service. It is
very simple (I wrote it only for test kepler with web service actor that
support complex types) and the type used as input/output methods is a simple
Class with 3 fields of the type string. In future I will need kepler to
invoke Web services with more complex data types, for instance, an
aggregated Class based on other classes. 

Thanks in advance
Luis Assuncao

Hi Luis,

Could you send the workflow xml file? I would like to know
what web service URL causes this problem.

Thanks,
