Hello there!
I'm trying to use the ForEach tag in Jelly's XML tag library. The
following script works fine in a standard Java console application:
<x:parse var="doc">
<a>
<b v="1"/>
<b v="2"/>
<b v="3"/>
</a>
</x:parse>
<x:forEach select="$doc/a/b" var="x">
...
</x:forEach>
However, if using Jelly on an application server, from inside an EJB
container (session bean), running the script above hangs, and 100% CPU
utilisation comes. I realized while debugging that NodeComparator
class' getDepth method gets into an infinite loop and never returns.
If I remove two "b" elements from the xml fragment above (so only one
remains), it works fine. It also works if I change the second part of
the above script to the following:
<x:forEach select="$doc/a">
<x:forEach select="b">
...
</x:forEach>
</x:forEach>
Does anyone have any idea why is that happening? Any help is much appreciated.
Thank you:
Csaba
