Cause:
======
Using Dashboard-, Query- and InferenceAgent class in the same ProcessUnit is not allowed.

Resolution:
===========
Create and start a new ProcessUnit(PU) that includes the Dashboard agent-class only and remove the Dashboard agent-class from the other PU .

Note: This is a known issue and reported as a restriction in the release notes of TIBCO BusinessEvents Views.

BE-17730
Summary: A runtime exception is thrown if an inference agent and a dashboard agent are started together as one processing unit(PU) and both try to access the dynamic query agent.
Workaround None. Starting more than one agent in a PU (or a single JVM), where all of the agents access the dynamic query agent, is not supported.
