Hi,

 

With skynav-fop-de1b874, I get a NullPointerException in batik.  I don’t think the problem is due to skynav.  I also get a null pointer exception in fop-1.0, but without a stack trace.  I suspect the fop trunk has been updated to include a stack trace in this case.

 

In any case, the attached .fo file won’t render the SVG with FOP.  It seems to be complaining about a gradient I’ve defined but I don’t know which one or why.

 

Could anyone on this list help me with an insight or a work-around?

 

If I get rid of ALL the gradients the PDF renders fine, but my PDF rendering is supposed to be duplicating the HTML rendering of the SVG, which employs the gradients successfully in for example FireFox.
