Re: side effects when debugging with xalan

Posted by Gordon Chiu <gr...@cvs.apache.org>.
Hi Nick,

You appear to be describing bug 16222, which has been fixed. Please try
the latest version of Xalan. I noticed you're using JDK 1.4 so please also
note this FAQ entry: http://xml.apache.org/xalan-j/faq.html#faq-N100CB on
how to use the latest Xalan version with your JDK.

If you're still getting an incorrect result with the latest version,
please open a bugzilla report and attach a test case. Thanks!

Gordon
