Caused by: java.lang.NullPointerException

Are you setting all parameters used by the XSLT?  Can you verify you do?

I am doing transformation with XSLT and C2.2. When there's something wrong with

Nothing tells me anything about the error message from the XSLT. Is there a way 
to know what is going on ??

Thank you.

I will check again, however for the future, how can I tell if a
parameter is missing or not set in the XSLT ??

RE: Error message for xslt

2012-12-13 Thread Robby Pelssers 
Well.

You can easily check if that XSLT uses parameters... right?

And at some point you invoke that transform from the sitemap:

map:transform src=someXSLT.xslt/  !-- this one does not set parameters--

map:transform src=someXSLT.xslt
  map:parameter name=param1 value=TEST/
  map:parameter name=param2 value={2}/
/map:transform

Just check whether you set the parameters correct in your sitemap... and you 
should be able to tell if the values which you set don't have a null value.

Re: Error message for xslt

2012-12-13 Thread Mansour Al Akeel 
Robby, this was not my question.
My question was, how do I know the source of the error in the XSLT file.
In my xslt I have a lot of param, but that is not an issue. Some
variables inside the xsl are generate from the parsed documents, and
those can be a source of error. Having a descriptive error message,
will help solve issues quickly.

I hope this clarifies the question.
