OSB11g - using Concatenation function in report key - Xpath

Question

Hi,
I am trying to use Concatenation function on Report key Xpath. For that i am using Following Xpath Expressions But this expressions not valid when trying to validate. But same expressions are valid under different scenarios in OSB.
1.fn:concat(./bpel:process/bpel:input, ./bpel:process/bpel:input)
error msg(when validate):_
error: XPath expression invalid, not a selection: declare namespace jca = 'http://www.bea.

2. op:concatenate(./bpel:process/bpel:input, ./bpel:process/bpel:input)
While using this Xpath expression validation is sucessfull but concatenation operation is not working when checked in the message reports under operations tab.
Can any one help me on this.
Thanks in advance.

Answer 1

can you try assign concatenated value to some xml element first, like
assign : <value>{fn:concat(a,b)}</value> to e.g. value
and then report key ./text() in variable $value
