Description Jiri Pechanec 2013-10-02 08:48:33 UTC 
Try following deployment
1 RTGov server
3 SY servers with rtgov client configured to use the server

Use demos/cluster qs. When the dealer invokes remote credit service then on the remote node there is an exception thrown

Comment 1 Gary Brown 2013-10-10 15:46:09 UTC 
Hi Keith

Need some switchyard support :)

I believe this is occurring because I store the 'request' activity event in the exchange, so that when the 'response' activity is being processed, it can retrieve the 'request' activity event to initialize the service type - as this is not available when the request is initially being processed.

Is this assumption correct? i.e. that the request activity event is being passed with the exchange between switchyard environments - so the activity event is being serialized as json, but upon deserialization the classes are no longer available?

If so then need a way to postpone deserialization until value is actually required, which in this case will only be within the rtgov event listener.
Comment 2 Keith Babo 2013-10-10 18:31:47 UTC 
It is definitely the case that context properties are serialized for cluster invocations unless they are marked with the transient label.  If you just care about keeping the property on the request side of the invocation, then mark it as transient and it will still be there when the invocation returns.  IOW, it stays in the in-memory version of the exchange but it is not propagated to the other instance.

Let me know if that doesn't help.
Comment 3 Gary Brown 2013-10-11 12:54:26 UTC 
Was also able reproduce using the remote-invoker quickstart in swyd 1.1.M4.

However when testing fix in swyd 1.1.M4, got the following exception in the client:

[INFO] --- exec-maven-plugin:1.2.1:java (default-cli) @ switchyard-quickstart-demo-cluster-client ---
Oops ... something bad happened.  org.switchyard.HandlerException: org.switchyard.SwitchYardException: SWITCHYARD010813: Cannot convert from 'org.switchyard.quickstarts.demo.cluster.Offer' to 'org.switchyard.quickstarts.demo.cluster.Application'.  No registered Transformer available for transforming from 'java:org.switchyard.quickstarts.demo.cluster.Offer' to 'java:org.switchyard.quickstarts.demo.cluster.Application'.  A Transformer must be registered.
