I'm using Eclipse BPEL Designer and Apache ODE. Then I'm trying to deploy my process in catalina.out I'm getting error org.apache.ode.bpel.iapi.ContextException: Deploy failed; error: [CompilationErrors] Compilation completed with 1 error(s):

As I understand, I need to initialise variable to let ODE know it type. I did it. Do you see the error? How can I fix it?
EDIT: Error in this assign operation
<bpel:copy ignoreMissingFromData="yes">
<bpel:from
expressionLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0">
<![CDATA[concat($ns2:expertSelectionResponse1.payload,

</bpel:from>
<bpel:to part="arg0" variable="CreateTaskPLRequest"></bpel:to>
</bpel:copy>

$ns2:expertSelectionResponse1.payload is not a valid variable name. The correct name is apparently SelectExpertPLResponse1, which is declared to be of type ns2:expertSelectionResponse. So the following snippet should work then:
<bpel:copy ignoreMissingFromData="yes">
<bpel:from expressionLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0">
<![CDATA[concat($SelectExpertPLResponse1.payload, "123","312","12")]]>
</bpel:from>
<bpel:to part="arg0" variable="CreateTaskPLRequest"></bpel:to>
</bpel:copy>
