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.
