Subject Re: class mediator and error handling
Date Mon, 14 Aug 2017 02:40:04 GMT
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.
