Joining a table created from a Web Service with another gives NPE in JBEDS

Issue

• After creating Relational tables from a WSDL, I'm now trying to join the resulting view that was created from the invoke procedure with another relational table and receive a Null Pointer Exception (NPE) when querying this table
