> We are encountering a strange issue in Production environment which we are not able to
replicate in any environments. The Order Process & Management application which generates
this error processes thousands of orders in a day avg. 4000 order. The order xmls are transformed
using various xslt to update order data. There is no XLS transformation exception thrown but
the xml output is not what is expected which leads to an "OrderUpdateException" being thrown
by the application API. 
> When this exception occurs, there are always 2 orders involved i.e. 2 different order
xmls being transformed at the same time(same timestamp) using same xslt. The resulting XML
transformation output for both the orders are also well-formed but due to incorrect value
evaluated by a variable declared inside <xsl:for-each, wrong path information is being
supplied to <Add instruction for updating the order. Morever, the issue seems to go away
on retry of order task from the application web client. As a result, the orders get updated
and processing continues. Here retry means applying the same transformation again on order
xml. The input order xmls were not modified whatsoever during retry.
