Are there any examples on using either doXslTransform or Xpath exetensions with arrays that would help me with my own configuration?

Hi Monika, The standard WS-BPEL assignment only supports copying content from a single node to a single node, both sides having to exist (in your case the sub-expression submitResponse[1] fails because it doesn't exist). To work with lists you either have to use the doXslTransform standard function or one of the XPath extensions that we provide with ODE: http://ode.apache.org/xpath-extensions.html Thanks, Matthieu On Mon, Dec 29, 2008 at 8:15 AM, Adamczyk, Monika < [email protected]> wrote: > Can someone tell me or point to an example how initialize in bpel process > a variable that is of mesageType, with the part being an array. > One of my assignment statements needs to copy another variable to the first > position of that array, but because this variable is not initialized, I get > an Xpath exception: > Unmapped Fault : { > http://docs.oasis-open.org/wsbpel/2.0/process/executable}selectionFailure<http:/ /docs.oasis-open.org/wsbpel/2.0/process/executable%7DselectionFailure>: > No results for expression: {OXPath10Expression > $planOutputs.body/plan:submitResponse[1]} > > I am fairly confident that the Xpath expression for the assignment is > correct, because another assignment from a variable which is also > messageType with its part being array ( see planInputs below) to an > individual variable works.
