Hi!
I am not sure if this is a bug or not, but when I have code similar to the
following:
$p-response-msg.response-part/x:e-response/xfer:r-info[$r-number]/x:l-ticket[1]
or
$p-response-msg.response-part/x:e-response/xfer:r-info[position()=$r-number]/x:l-ticket[1]
I get a null (see below). But when I replace the $r-number with a constant '1'
it works. The value of $r-number is 1 as shown in the debug output. $r-number
is declared as <variable name="r-number" type="xsd:int" />
I am using a war file built from the trunk sometime last week.
I am using xpath 2.0 as query language and expression language. The BPEL 2.0
spec talks about using multiple variable references in xpath expressions, so it
would seem alright.
Thanks!
-Doug.
