Hi,

in the following example the line from the group with the id rudy is animated 
without a problem. However the filter referenced through the xlink is cut off 
after a few moments of the animation. I assume it's a problem with it's 
clipping area...

(Using Squiggle from batik-1.7beta1 under Windows XP)

Many thanks!

Stevo

Hi Stevo.

Yes that is indeed a bug.  There is a bunch of areas in Batik where referenced
elements (such as the referenced filter here) are not updated when the
referencing element changes.  It might be some time before this one is fixed, as
it will require a fair amount of work to do right.
