Referencing incoming XML in start node

Question

Hi,
(Using WLI 2.1, WLS 6.1)
Just wanted to clarify an issue that is at the root of an earlier thread.
When configuring my workflow in Studio I seem unable to use an Xpath function
as part of the key expression in my start node.
The following generates an exception when I try to save it
ToString(XPath("/Trade/tradeid/text()"))
The exception is
"The server was unable to complete your request.
Workflow error: The XPath function requires an XML document.
Workflow error: com.bea.wlpi.evaluator.EvaluatorException: The XPath function
requires an XML document.
     <<no stack trace available>>"
I've defined the event expression for Trade, have specified Trade as my root element
in tthe start node, and have successfully used the same Xpath expression in the
key expressions of subsequent event nodes without trouble.
According to the Xpath documentation if I don't specify the XML document as a
parameter it will assume its the incoming message. This is exactly what I want.
any ideas ?
Cheers,
mairt

Hi Mark
You've posted this in the wrong forum. Try LiveCycle Designer, instead of LiveCycle Workflow Designer :)
