Chain/Gateway error handling

[sseaman]

I have a chain that uses gateways to call other chains and I want to ensure that if one gateway call fails from an error the other items in the chain still execute.

Here is my current configuration:

 	<gateway id="profileGateway"
		service-interface="someInterface"
		error-channel="profileHmkFailureChannel"> <!--  global catch -->
		<method name="login" request-channel="profileServicesInputChannel"
			reply-channel="profileServicesOutputChannel" 
			reply-timeout="40"
			request-timeout="40"/>
	</gateway>
<!--  ROOT CHAIN -->
	<chain input-channel="profileServicesInputChannel" output-channel="profileServicesOutputChannel">
		<header-enricher>
			<header name="profile" ref="profile"/>
			<error-channel ref="profileHmkFailureChannel"/>
		</header-enricher>
			
		<transformer method="transform" ref="profileToHmkUserTransformer"/>
		<gateway request-channel="profileHmkInputChannel" request-timeout="10"/>
		<transformer method="transform" ref="profileToHmkOrgTransformer"/>
		<gateway request-channel="profileHmkOrgInputChannel" request-timeout="10"/>
		<transformer method="transform" ref="profileToAcsTransformer"/>
		<gateway request-channel="profileAcsInputChannel" request-timeout="10"/>
	</chain>
	
	<!-- START - Info -->
	<chain input-channel="profileHmkInputChannel">
		<header-enricher>
			<error-channel ref="profileHmkFailureChannel"/>
		</header-enricher>
		<service-activator method="getUser" ref="hmkUserService"/>
		<transformer expression="@profileHmkTransform.transform(payload, headers.profile)"/>
	</chain>

As you can see I've tried using the header-enricher in both places but it never seems to get called. I am able to catch the error (caused in service-activator ref=hmkUserService) at the profileGateway but by that time it is too late and the error has causes the chain to exit.

My questions are:
1) Is there a way to tell the 'root' chain to keep going even if there is an exception in one of the gateway calls?
2) Is there a way to have each gateway send errors to their own error-channels (the header-enricher doesn't seem to be working)
3) Could I be doing this a better way?

Thanks in advance!

Ok, the issue is that we need to allow error-channel on the <gateway> element within the chain.

Could you please open a JIRA issue for that?

Thanks

Ok I created a JIRA https://jira.springsource.org/browse/INT-1745
Should be ready for 2.0.2
