hello folks!
im running batik 1.6 and after all troubles i went thru getting this
thing to run i thought its working and stable. but for some strange
reason sometimes when i load a new svgdocument into the canvas i get the
following exception (happens about 1 in 50 loads):
118453 [main] ERROR com.diligentit.util.DefaultApp -
org.eclipse.swt.SWTException: Failed to execute runnable

i always reuse my jsvgcanvas and use the following commands to load the
new svg document into the canvas (and yes the document i load is set):
svgCanvas.stopProcessing();
svgCanvas.setDocument(_document);
svgCanvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
svgCanvas.flushImageCache();
line 443 in the exception is the line where the setDocument()
instruction is. do i do anything wrong when loading a new document onto
the canvas? any ideas what could go wrong? the "Unknown Source" line in
the exception irritate me a bit, they make it hard to track down the
error. does anyone has similar problems?
thanks,
marc
