Direct Port Binding

Question

Hi,
I have one orchestration which process the incoming message and send messages using Direct Send Port. Refer the below message.
<ns0:Item xmlns:ns0="http://Services.Foundation.Schemas.CRM_WorkQueue">
  <ContactId>fe296e5d-a520-e311-a249-00155d016fdf</ContactId>
  <MasterQueueId>c54ffde9-b4f6-e311-8818-00155d016f71</MasterQueueId>
  <EntityId>c44ffde9-b4f6-e311-8818-00155d016f71</EntityId>
  <WorkType>clientcaredoc</WorkType>
  <DateLimit>2014-06-18T06:51:29Z</DateLimit>
  <RequestResultsXML><![CDATA[]]></RequestResultsXML>
</ns0:Item>
I have few orchestrations which consumes this message. I have direct receive port using filter expression on based worktype. I am getting the below exception from the main orchestration. If I change the send port configuration to 'specify later' to send
a message to folder, it is working fine.
xlang/s engine event log entry: Uncaught exception (see the 'inner exception' below) has suspended an instance of service 'Foundation.Orchestrations.CRM_PollWorkQueue(ef25a9ce-7094-50ea-f4ac-4e6ba40223e2)'.
The service instance will remain suspended until administratively resumed or terminated. 
If resumed the instance will continue from its last persisted state and may re-throw the same unexpected exception.

Hi Laxme,
Overseen the details of the error message you have posted. I think the error is due to no subscribers found for the message published by the direct bound orchestration. If you have another sub-orchestration/process which matches the subscription of the message
published by direct-bound send port, it will work. Seems like message published by direct bound orch and sub-process is not matching.
To make this work, you can check the context of the message outputted by direct-bound orchestration. Or just create a send port subscribing to the message published by the direct-bound orch. Check the context and create a subscription matching the context.
Otherwise you will get the error as above.
