I was goofing around with some stylesheet, that my editor declared as syntactically correct and one of the changes did blow up like this. I don't think I do anything out of the ordinary no XSP, Woody, or Flow - strait xml aggregate --> xhtml. It is no hinderence for my project. I raised the severity to major, because I'm used to do so for any NullPointerException from work - because they are so avoidable. And in this case the thread really died w/o writing to the access log or sitemap log anymore. I'd concider catching this in Cocoon even if it is a Xalan bug. I hope that helps. I'm sorry that I don't have a better test-case. Kaj
