Subject Re: Duplicate image references in SVG
Date Thu, 02 Oct 2003 17:45:28 GMT
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?

Thanks in advance.

Andres.
