> Hi all
>
> I am triggering an xpl pipeline through the OrbeonServletContextListener and
> getting the exception below.
>
> If I trigger the same pipeline from epilogue-servlet.xpl, it works fine and
> I get no problem. The pipeline has no input paramterers, calls oxf:xslt and
> then oxf:xforms-submission, where it seems to fail.
>
> Bug? Any hints would be very much appreciated.
