When implementing a MessageListener, the listener works as expected when Message(...) is in the primary CQL file. However, when Message() is in a referenced library, it does not work as expected.
For example, FHIRHelpers has several different Message() calls, but they will not trigger a call to an implemented MessageListener.
In debugging, a NullMessageListener would be instantiated for such library Message calls. I discussed with @cmoesel, who identified that this.messageListener should be added as a final parameter in the constructors here and here. I tried out this solution, and it appears to have resolved the issue.
I'd like to ask that this solution be considered and added.
