Re: NPE when using HSSFSerializer + big pipeline
I've moved both your emails to a folder named tasks. I will look at
this and get back to you. By the looks of this error it looks like
invalid data (a null where it expects characters).

Hello,

Notice at the end, I use the HSSFSerializer. I currently am getting a
huge string of NPEs in the error.log (included below).
When I change to the xml serializer or the html serializer, it works
great. Also, I've tested the output from final.xslt (saved as raw xml)
and piped it directly into the HSSFSerializer which worked great. I
only get the NPEs when using the above pipeline.
Does this NPE make any sense? (note: I'm currently trying different
permutations to isolate the error)
Any tips or help would be greatly appreciated! I'm so close. :)
Thanks,
Seth

By the looks of this error it looks like invalid data (a null where it expects characters). Thanks! I'll keep poking around, trying different things. Is there a strategy for debugging? I'd like to do a trace, or watch what happens to try to identify the offending data. What confuses me is that if I take the XML being produced and manually run it through the last step (which is the serializer) then it works great. It's only when it's being run through the pipeline directly does it fail. So at first I thought it was bad data, too (as the exception seems to indicate) but the generated XML seems OK. Now, of course, the SAX events might be getting screwed up and it might only work OK when run through the XML serializer. If you have some suggestions on how to get more debug or watch the processes, that would be wonderful. I'll also send you all the style sheets, etc if you'd like to try it. Thanks very much, Seth ps In the meantime I'll probably write my own HSSFSerializer (a simpler one). Maybe this will help track down the problem? - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faqs.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
