rect element mouseclick triggers ClassCastExeption

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

I complied Batik 1.5 with only the patch files mentioned in
http://koala.ilog.fr/batik/mlists/batik-dev/archives/msg03536.html

    * Subject: cvs commit:
      xml-batik/sources/org/apache/batik/script/rhino
      EventTargetWrapper.java
    * From: vhardy@apache.org <ma...@apache.org>
    * Date: 13 Jul 2003 22:30:57 -0000
    * To: xml-batik-cvs@apache.org <ma...@apache.org>

I have not added any patches or other modifications to the Batik code.

Thanks in advance,

Andres Toussaint

Hi Andres,

    I think the problem is your code:

 > java.lang.ClassCastException
 >        at
 > com.onemileup.client.draw.BaseDrawing$OnDownAction.handleEvent(Unknown
 > Source)

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