BPEL Correlation: ORABPEL-03812 Cannot find property alias.

Question

HI,
I have created a BPEL process, that places a message into a JMS queue, and waits to receive a response in anoter JMS queue.
In both the request and response message types, there is a uuid field, that has been populated initially with generateGUID() function etc.
I plan to correlate based on this value.
I am using correlation sets to correlated to the BPEL instance using the uuid field in the request and response fields.
Ive gone by the book i.e. BPEL developer guide, in creating the Correlation set, property, property aliases etc.
I am able to successfully compile and deploy the process.
But on execution of the BPEL instance i get error as follows.
<default.collaxa.cube> <BaseCubeSessionBean::logError> Error while invoking bean "cube delivery": Cannot find property alias.
Cannot find the property alias "{http://pli.techm.com/JMSAsyncSyncProcess/correlationset}jms_uuid", message type "".
Please check your BPEL/WSDL source to make sure that property alias "{http://pli.techm.com/JMSAsyncSyncProcess/correlationset}jms_uuid" has been defined.

Cannot find property alias.
Cannot find the property alias "{http://pli.techm.com/JMSAsyncSyncProcess/correlationset}jms_uuid", message type "".
Please check your BPEL/WSDL source to make sure that property alias "{http://pli.techm.com/JMSAsyncSyncProcess/correlationset}jms_uuid" has been defined.
Due to this the BPEL process instance itself is not created and thus no further action can be taken.
Ive ensured that all necessary imports into the various wsdl files (including partner wsdl files) are present.
Can somebody please help?

Hi,
I solved the problem too :)
In the outbound jms adapter call, where the correlation is be started, there is an in|out|in-out attribute that needs to be set to out. probabaly signifies the outbound message from that node.
This worked :)
let me know if you tried something else...
