In synapse 1.0, I am using a custom class mediator in the inSequence of a proxy service. How do I generate a SOAP fault from the custom class mediator? Returning false in the class mediator doesn't seem to do trigger the faultSequence for the proxy service. Throwing exceptions in the class mediator doesn't seem to trigger the faultSequence either. I can get the proxy service fault Sequence to run only if the in Sequence "send" fails, never with the custom class mediator that precedes the "send". I have looked at sample 510 that describes what the synapse.xmlneeds to look like for custom class mediators, but I can't get that example to generate a SOAP Fault either. Do I need to write directly to the Synapse MessageContext in the mediator? ~john
