Element 'append' not expected – BPEL 2.0

Question

Hi,
I have a BPEL 2.0 process and I am trying to use the append activity as follows:
<assign name="AssignResponseData">
<copy>
<from>$OnMessage_Ebiz.part1/ns2:DataArea</from>
<to>$outputVariable.part1/ns2:DataArea</to>
</copy>
<bpelx:append>
<bpelx:from>$OnMessage_EbizOSS.part1/ns2:DataArea</bpelx:from>
<bpelx:to>$outputVariable.part1/ns2:DataArea</bpelx:to>
</bpelx:append>
</assign>
This matches the documentation:
http://docs.oracle.com/cd/E21764_01/integration.1111/e10224/bp_manipdoc.htm#autoId34 – section 6.14.1.2 bpelx:append in BPEL 2.0
but I am getting the error Element append not expected. Also bpelx:append is underlined in Jdeveloper and I get an error message saying No Grammer.
Can anyone tell me what I am doing wrong?
Thanks
Robert

Answer 1

Hi,
Thanks for the responses. I am afraid they have not solved the problem.
I have the bpelx namespace defined in the process tag and it is as Vvaladodias suggests.
also the default namespace is as follows:
xmlns="http://docs.oasis-open.org/wsbpel/2.0/process/executable"
Also based on Naresh's comments I changed the From Element. (The Dataaarea element contains mutiple system elements. I want to come out with 1 dataarea and mutiple system elements)
I have changed the assign to two separate assigns look like:
<assign name="AssignResponseData1">
<copy>
<from>$OnMessage_Ebiz.part1/ns2:DataArea</from>
<to>$outputVariable.part1/ns2:DataArea</to>
</copy>
</assign>
<assign name="AssignResponseData2">
<bpelx:append>
<bpelx:from>$OnMessage_EbizOSS.part1/ns2:DataArea/ns2:system</bpelx:from>
<bpelx:to>$outputVariable.part1/ns2:DataArea</bpelx:to>
</bpelx:append>
</assign>
Now the second <assign> start tag is highlighted with the message 'Required child missing from element assign'
