Batik's DOM implementation prevents you from creating elements in the SVG Namespace that aren't part of the SVG specification. As far as path forward, I would suggest taking the code to create the circles and put it in a small example that just puts of the canvas (with any old document) and a button that adds a list of preset circles. Then with all the code together I can either spot the error or run it and debug why it isn't working for you. > > at org.apache.batik.dom.AbstractNode.createDOMException(Unknown Source) > > at org.apache.batik.dom.svg.SVGDOMImplementation.createElementNS(Unknown > Source) > > at org.apache.batik.dom.svg.SVGOMDocument.createElementNS(Unknown Source) > > at mypackage22.KeyAccidentClient$4.run(KeyAccidentClient.java:349) > > at org.apache.batik.util.RunnableQueue.run(Unknown Source) > > at java.lang.Thread.run(Thread.java:534) > > Pls advice. > > Thx > > yasmin > > > > > > Hi Yasmin, > > > > [EMAIL PROTECTED] wrote on 03/12/2006 06:04:36 AM: > > > >> When I tried putting a line to test if the code is running, the code > > does > >> run, but apparently it does not create any elements, here's what I > > tested: > >> > >> System.out.println("This is just testing :" + > > g.getAttribute("circleGroup")); > >> > >> and nothing prints for g.getAttribute ... > > > > This is expected, I think you want to use: > > g.getAttributeNS(null, "id"); > > > > This should result in the string 'circleGroup'. > > > >> > [EMAIL PROTECTED] wrote on 03/11/2006 05:44:31 PM: > >> > > >> >> I did initially try to add the red circles to the svg document > >> >> programatically, infact I think you emailed me a snippet of your code > >> >> but it doesn't work, the code compiles but does not display the > >> >> red-circles, I tried to repaint my canvas, that don't work... here's > >> >> the code I'm using maybe you might be able to spot where I'm making > >> >> the error... > >> > > >> > The code looks pretty good.
