Hi Thomas,
thank you very much for the quick fix and the hint to avoid that problem
in older releases! I will have a look at the solitaire example.
I can confirm that my example works now fine in the SVN version.
Thanks again,
Andreas

Hi Andreas,
This turned out to be a bug in Batik's event proxies for JavaScript.
The basic form of the bug is that if you registered for two events on the
same 'listener' the remove would only ever remove the last registered
listener.
The best workaround for this would be to introduce small 'forwarding'
listeners. This is what I tend to do in this case and likely the reason
it
wasn't noticed earlier. For an example of this take a look at my
solitaire
examples. In particular util.js has some 'forwarding' function objects
and the pile.js uses them as members which it registers so that it gets
it's 'mousemove' function called for mouse moves instead of the
generic 'handleEvent'.
This is now fixed in SVN.

Hello,
I have a problem with the following selectionList / ECMAScript Code and
removing eventListeners from my document.documentElement.
I am refering to the example at:
http://www.carto.net/papers/svg/gui/selectionlist/index.svg
When one opens a selectionList, I add a "click" and "keypress" event
listener to the document.documentElement in order to allow for open
selectionlists to close if the user clicks outside the selectionlist.
This works fine in Batik, the selectionlist closes properly when the
event was received from the svg-element. However, it seems the event
listener is not properly removed from the document.documentElement
(which should be done in the file "selectionList.js" in the method
".foldList()"). Maybe I am doing something wrong, but I don't find my
mistake. Why aren't the eventListeners properly removed?
There is a tar.gz archive of all related files available at
http://www.carto.net/papers/svg/gui/selectionlist/selectionList.tar.gz.
Any help on this problem is very much appreciated.
I tested with the latest svn release and also with batik 1.6 with the
same results/problems.
Thanks a lot,
Andreas
