I have a problem testing fop functionality. I have a very simple idoc:
=========================================================
<idoc>
<seq>
<instr>
<type>copy</type>
<operand>file:///C:1060-NKSEDK-2.0.3modulesBenchmarkcontentsample.xml</operand>
<target>var:message</target>
</instr>
<instr>
<type>xslfo-fop</type>
<operand>var:message</operand>
<operator>
<xslfo-fop>
<type>pdf</type>
</xslfo-fop>
</operator>
<target>this:response</target>
</instr>
</seq>
</idoc>

==========================================================
when i attempt to execute it i get the following error:
***********************************************************

Being new to 1060 - i am finding this very difficult to trace. I know the source fo file (sample.xml) is ok as i
can convert it to pdf directly via fop and via cocoon.
Also the xslfo-fop install had no problems.

Please let me know if this forum is the correct place to
ask such questions.

Franco

I've looked at the xslfo module and found a bug that matches your scenario. It works when inputs are passed by value but not when passed by reference. See:
http://www.1060.org/bugxter/main/edit_bug?id=44

If you look at the last entry in the trace you see that the xslfo module itself is trying to resolve your application specific resource. This is because of a wrongly configured <mapping/> section on the xslfo module definition.

It is a trivial fix that I'll get rolled into the next release. To patch your version you'll need to follow the following steps:

1) expand the xslfo module
2) edit the module.xml file in the root directory and replace the <this/> tag with <this><match>ffcpl:/xusr/.*</match></this>
3) jar the module up again
4) replace the old with the new

Thank you for your quick response, that fixed the problem. Seems to be working well now.

We've posted a patch for the ext-xslfo module...
