Both Actions Listeners DO get fired, so it is up to my code to determine which of the duplicates is triggering the event, right?
If this is so, Is there a place in Batik i can intercept the Event to kill those not wanted, and only propagate the one i want?
This bug should now be fixed in CVS.
Thanks in advance.
Andres.

Hi All,
When I add two instances of the same image to my document via the <image> , and add a actionListener to the group, only the first instance of the <image> reacts to the actionEvents.
Hmm, are you sure that both of the action listeners aren't being fired? The problem is that currently we have one copy of the document linked to two graphics trees. So Both image element bridges should be registering action listeners on the root svg of the referenced SVG document.
We should probably just have the ImageNode in the rendering tree
check it's outline and if the point is in the outline forward the event
as it is the event traverses down into the referenced image (which allows
things like 'pointer-events' within the referenced image to function
properly.
How can I have duplicate references to the same image inside my SVG, but that behave as individual instances to the EventListener? (I am using a JSVGCanvas to represent the document)
For instance, i want tyhis image *xlink:href="../equipment/aircraftSpruce/M07TACH.svg" uid="OMU_93", and the same one, with uid="OMU_93_2" *to be placed on different loations on the canvas, and to react individually to the MouseEvents. Each is placed in its own Element.
I am aware that perhaps this is an SVG related issue, but any head start would be truly appreciated,
Andres.
Abstract of the Element constructor:
String svgNS = "http://www.w3.org/2000/svg";;
String xlinkNS = "http://www.w3.org/1999/xlink";;
Element img = document.createElementNS(svgNS, "image");
img.setAttributeNS(null, "x", x.toString());
img.setAttributeNS(null, "y", y.toString());
img.setAttributeNS(null, "width", width.toString());
img.setAttributeNS(null, "height", hgt.toString());
img.setAttributeNS(xlinkNS,"xlink:href", image);
img.setAttribute("uid", uid);
imgGroup.add(img);
