Its illegal to assign a XML value directly to the messageType variable

Question

I was recently working in JDeveloper 11g (11.1.1.7.0)  on an internal SOA project making some changes in the BPEL and noticed this message: Error(172): its illegal to assign a XML value directly to the messageType variable "InvokeFetchUpdatedUserId_FetchUpdatedUserID_InputVariable" I searched for this error message and didn't find anything.  The message is somewhat explanatory but I thought I would post the fix here just in case.  I modified my assign from the following:                                                                                                                           To this making sure to assign it to the underlying entity.                                                                                                                           Then it compiled just fine. Thanks, Tom

Answer 1

In case if you are returning multiple value or with multiple columns then you have to use record or cursor to do that operation.
