Failed to execute pipeline.: Errors in XSLT transformation
I have tried several xsl and after double checking each of them I am stumped.
I found several zarros in bugzilla. In mail list I have seen several "Failed to execute pipeline" and a couple related to NPE, but none linking either to "Errors in XSLT". Worse these other msgs don't indicate what solved the their problems.
I am running 2.04 on w2k and I sure could use a clue. All classes immediately surrounding the error are all cocoon. I have been studiously avoiding 2.1 beta chaos. Is it now time to dive in? will that help?

Sorry I can't be much help here, but I will say that this Exception
and your tale of woe does look vaguely familiar to me. The voices of my
memory are whispering 'namespaces'. I find dealing with namespaces one
of the more gnarly parts of xml, especially with SAX. My suggestion is
(and this is an almost complete shot in the dark) to define a namespace
and prefix for your local elements.

Re: Failed to execute pipeline.: Errors in XSLT transformation
Posted by Joerg Heinicke <jo...@gmx.de>.
Hello Don,
there is nothing wrong the XSLT itself, so "Errors in XSLT" is not a
correct message. But I can't tell you, what the error is.
I "refactored" the stylesheet using templates instead of for-each. If
there is a bug in Xalan 2.3.1 (this should be the version used in Cocoon
2.0.4), it will maybe already work. Another suggestion is to update the
Xalan version to 2.4.1. This sometimes solves some problems.
Regards,
Joerg

this pipe works and results in the p1.xml attached.
generate type="session-attr"
serialize type="xml"
result is p1.xml (attached)
Yet this pipe does not generate type="session-attr"
transform src="person.xsl" (attached )
serialize type="html" (never gets here)
result is this error

you may need to post your xsl. it's unclear from what you say below -
if you comment out all transfomers, does the exception go away?

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>

In cases like this I do the following:
1) make sure the pipeline is giving the transformer in question the
right input. (ie comment out the transformer and any subsequent ones and
use XMLSerializer)
2) make sure the stylesheet works outside of cocoon. (you can do step
one to get the appropriate input)

Hey Don,
Could you maybe try to put in a log transformer before your XSL and send
the output of that as an attachment? I'm not sure but just maybe the
error is caused by some invalid SAX-events being generated.
The logtransformer can be used as follows:
<map:transform type="log">
<map:parameter name="logfile" value="output.txt"/>
</map:transform>
and then all sax-events will be logged to the file output.txt.
