"invalid assignment target" error in Rules
We are using 11g, PS2. When executing a Rules session called by BPEL or Mediator, we are getting a strange error: "invalid assignment target". There is also "Rule session pool object does not exist" in the error messages.
The strange thing, we can call all of our rules successfully from a plain old Java program, so I don't think there is anything wrong with the rules themselves.
How can I figure out what is wrong? I'm out of ideas.
