null error when setting the begin attribute to "Animation.end"

[Ludo35 <lu...@oracle.com>]

Hello,

I am trying to script the animation of bubbles so that one starts after
another one.
When I do a animNode.setAttribute("begin", "Animation__1.end"); it throws an
null error in Squiggle 1.7.
Could you please take a look at this simple example and let me know why this
error is thrown?

Thanks in advance,

Ludo

Also confirmed using the trunk version (1.8 revision 733247) and JDK
1.6u11 in Windows XP SP3. An NPE is displayed (partial transcript):

java.lang.NullPointerException
	at org.apache.batik.anim.timing.SyncbaseTimingSpecifier.<init>(Unknown Source)

This may be somehow related with bug 46452 [1] and with a comment by
dvholten in revision 656363 [2].

I'm not familiar enough with Batik's internals to give an informed
answer, but I hope this hints and/or helps someone with more expertize
to give more valuable feedback. ;-)

Cheers,
 Helder
