How do standard Business events work with WF_BPEL_Q?

Problem Scenario :

When a standard business event is associated with a BPEL subscription is raised, it goes to WF_DEFERRED queue and then to the WF_ERROR queue with either of the following error messages:

1) "ORA-01403: no data found" .


2) "ORA-24033: no recipients for message
Wf_Event_QH.Enqueue(APPS.WF_BPEL_Q, SQL err is ORA-24033: no recipients for message)
Wf_Event.Enqueue(, WF_EVENT_QH)
Wf_Rule.Default_Rule(, 4254112FCA341054E043C0A862191054)"

Expected behavior is that the Event should be enqueued in the WF_BPEL_Q for further processing.

Expected Flow: The normal flow involved for Standard Business Events with BPEL is as follows :

a) User from Jdeveloper creates/configures an adapter as a partner link and selects the APPS event to listen

b) These are the background items
1. Create tables for queue named wf_bpel_q
2. Start wf_bpel_q
3. Create and start wf_bpel_qagent listener, which listens on wf_bpel_q.
4. Create subscription for the event for which the partner link was created

c) When the BPEL process is deployed in the BPEL PM, the listener keeps polling the WF_BPEL_Q with whatever frequency was defined.

d) Once the event is raised, it is enqueued into the WF_BPEL_Q and the listener (spawned by BPEL PM) which is listening to this event, would dequeue the item and start the BPEL process.
