Tammo van Lessen commented on ODE-944:
--------------------------------------
... and let's hope that Dieter is not wearing the "food critics" heat on,
testing our BPEL knowledge :)
If I'm not mistaken, from-spec and to-spec must not select more than one node.
Here are the related parts of the spec:
Page 60:
A to-spec MUST return an lvalue. If a to-spec does not return an lvalue then a
bpel:selectionFailure MUST be thrown. An lvalue, in the context of XPath, is a
node-list containing a single node from a variable or a partnerLink identified
by the to-spec.
Page 61:
An optional <query> element may be used to select a value from the source or
target variable or message part. The computed value of the query MUST be one of
the following:
• a single XML information item other than a CII, for example, EII and AII
• a sequence of zero or more CIIs: this is mapped to a Text Node or a string in
the XPath 1.0 data model
CII is Character Information Item, EII and AII stand for Element II / Attribute
II.
But when looking at the code, I'd expect to get a different fault. Dieter,
could you please set the log level to DEBUG for org.apache.ode.bpel.runtime and
send us the logs?
Thanks,
Tammo
