Description Antonin Nebuzelsky 2004-12-17 14:36:43 UTC 
Repetitive activation of nodes A, B, A, B,...
always does parsing of the activated node,
although the file did not change at all.
Comment 1 David Simonek 2004-12-22 19:32:14 UTC 
Situation now alot better. Parsing is still being done, but now
parsing is 4x faster and doesn't block AWT anymore, so I believe no
caching is needed and bad impact of this bug is gone.

Re to Tim: As you already know, blocking was during Navigator's
painting, due to complexity and frequency of JMI calls done at that time.
Comment 2 Antonin Nebuzelsky 2004-12-23 11:01:48 UTC 
I agree that caching in this case is not needed.
