Hi,
I must push this mail again.
It now happened again multiple times to me, that the the method
canvas.getUpdataManager() returned null when the gvgTreeRenderer completed.
It happens seldom, but it does happen.
Please see again the code snipped in the quoted text.
Is it a bug in batik? According to the javadoc of the getUpdateManager()
method I would expect that it is guaranteed that getUpdateManager() won't
return null when being called after being informed of rendering completion.
Any help appreciated.
Regards
Marco
