Hi Andres,

I think the problem is your code:

    The class cast exception is happening in com.onemileup code which
is yours judging by your mail address.

Hello all,

Previously I had a trouble with the mouseaction events on a JSVGCanvas, that Thomas DeWeese was so kind to solve for us (covered in the thread "mousedrag and mousedown not detected").
My actual problem is i add a RECT element to my JSVGCanvas, doing this:
document = e.getSVGDocument();
documentElement = (SVGOMSVGElement)document.getDocumentElement();
Element imgGroup = documentElement.getElementById("imgGroup");
....
Element rect = document.createElementNS(svgNS, "rect");
....
imgGroup.appendChild(rect);
Then register the action listeners, and when i do a mousemove, it gets registered ok, but a CLICK, DOWN or UP, throws the following error: java.lang.ClassCastException at com.onemileup.client.draw.BaseDrawing$OnDownAction.handleEvent(Unknown Source) at org.apache.batik.dom.events.EventSupport.fireEventListeners(Unknown Source) at org.apache.batik.dom.events.EventSupport.dispatchEvent(Unknown Source) at org.apache.batik.dom.AbstractNode.dispatchEvent(Unknown Source) at org.apache.batik.bridge.BridgeEventSupport$Listener.dispatchMouseEvent(Unknown Source) at org.apache.batik.bridge.BridgeEventSupport$Listener.dispatchMouseEvent(Unknown Source) at org.apache.batik.bridge.BridgeEventSupport$Listener.mousePressed(Unknown Source) at org.apache.batik.gvt.event.AWTEventDispatcher.processMouseEvent(Unknown Source) at org.apache.batik.gvt.event.AWTEventDispatcher.dispatchMouseEvent(Unknown Source) at org.apache.batik.gvt.event.AWTEventDispatcher.dispatchEvent(Unknown Source) at org.apache.batik.gvt.event.AWTEventDispatcher.mousePressed(Unknown Source) at org.apache.batik.swing.svg.JSVGComponent$23.run(Unknown Source) at org.apache.batik.util.RunnableQueue.run(Unknown Source) at java.lang.Thread.run(Thread.java:536)
