Thanks Charles. I totally agree. and that is why I am stumped. To be sure the request is filled beginning with a <map:generate type="session-attr"> which I <map:serialize type="xml"/> and save the result as p1.xml.
THEN I test several xsl (just to be sure) on p1.xml. The xsl all pass both in xmlspy and xslerator. THEN removng the <map:serialize type="xml"/> and replacing with one of the tested xsl, <map:serialize type="xml"/> or <map:serialize type="html"/> (whichever is appropriate to the xsl) Still resutl in the bad voodoo reported earlier. Incidentally looking at CachingStreamPipeline, I found the below javadoc on the class. Maybe if I switch cacheing off? how? The real blister is that I was so sure I was finished. Don * This stream pipeline is able to cache the response, if * <ul> * <li>a) the serializer is cacheable</li> * <li>b) the <code>EventPipeline</code> is cacheable</li> * </ul> * ----- Original Message ----- From: "Charles Yates" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, March 31, 2003 4:24 PM Subject: Re: Failed to execute pipeline.: Errors in XSLT transformation > In cases like this I do the following: > > 1) make sure the pipeline is giving the transformer in question the > right input.
