In this case, i have a property alias defined for that message. What i did wrong
is that i used a second property that has a property alias with a different
message. Please see attached files for reference. The error message is misleading,

C:\Documents and
Settings\pvarghese\Correlation-FlowAsStartActivity\src\Correlation-FlowAsStartActivity.bpel:30:
column:24 ERROR: The property
"{http://j2ee.netbeans.org/wsdl/Correlation-FlowAsStartActivity}Corr-FlowAsStart-InboundProp2"
defined in correlation set "CSet1" does not have a propertyAlias defined in any
of the WSDL definitions directly imported by this BPEL process. You must add a
propertyAlias (in one of the imported WSDL definitions) for the WSDL
message-type/BPEL variable type used in the enclosing
<receive>,<reply>,<invoke>,<onMessage>,<onEvent> activity. The propertyAlias
must use one of - messageType-part, type or element attributes similar to how
the BPEL variable is defined.


In this case, the message should be something like,
"Corr-FlowAsStart-InboundProp2" doesn't have a propertyAlias defined for the
message where the correlationSet "cSet1" is being used (in the receive activity).
