Hi Matt, 

What you’re trying should work. I don’t see how anything in the class mediator 
can cause this as all it does is execute the mediate method of the custom 
class. If you do not handle exceptions in your custom class, the class mediator 
wraps the mediate method execution in a try/catch and that should at least 
throw a SynapseException. 


Thanks, 
Ravi
