Subject Q: Batik Extension/FOP problem
Date Thu, 04 Sep 2003 02:38:03 GMT
I got the same exception as what Swapan got. I think the
problem
is just what Thomas mentioned: "Is it possible that you are
mis-mapping the elements from FOP?  the batik:flowText element
needs to become a bati.extension.svg.FlowTextElement the others
need to be mapped likewise.  Just mapping them to generic
elements won't work."

My question is how to map the element to
batik.extension.svg.FlowTextElement. Once I set up the
BatikBridgeExtension and BatikDomExtension, getBridge() should
automatically map the DOM element to FlowTextElement. But
through debug, I saw the element is generic element not
FlowTextElement.  Can you please tell me what I am missing?

Thank you very much.
 
Jay

    I don't know, The error you are getting is indicative of
passing a
non Batik DOM node into Batik.  Is it possible that you are
mis-mapping the elements from FOP?  the batik:flowText element
needs
to become a bati.extension.svg.FlowTextElement the others need
to be
mapped likewise.  Just mapping them to generic elements won't
work.
