Description Jesse Glick 2004-11-24 21:56:37 UTC 
041124 custom, JDK 1.6 b13. Expanding Explorer
trees using the Right Arrow key does not do
anything the first time; sometimes it works if you
press Right Arrow again, sometimes not. Try it by
just starting IDE on a fresh user dir, then open
the Favorites tab and try expanding various
folders in ~ using the keyboard. On JDK 1.5.0 it
works fine in all cases. On 1.6 b13 it does not
work reliably.

Presumably a JDK bug, but need to isolate where
the problem is and file a more specific bug.
SwingSet2 does not seem to have this problem.
Comment 1 Petr Nejedly 2005-02-04 11:17:13 UTC 
I've seen it under 1.6. I have no idea what's wrong, but I'll try to
analyze it later.
Comment 2 Jan Chalupa 2005-02-25 18:15:26 UTC 
Still reproducible with JDK 1.6 b24 on Win XP. We'd better investigate
this and file a bug against JDK soon if needed.
Comment 3 Petr Nejedly 2005-02-28 16:01:00 UTC 
OK, I'll try to analyze it asap.
Comment 4 Petr Nejedly 2005-03-01 13:51:48 UTC 
It is caused by a change in JDK.
In BasicTreeUI, there is added a check for children count before
trying to expand a non-leaf node, which is IMO wrong.
It doesn't work for us because we have lazy model and each previously
unexpanded node has initially no leaves (although correctly reports it
is not leaf itself).

I'll file JDK issue for it.
Comment 5 Petr Nejedly 2005-03-01 14:05:46 UTC 
Submitted as JDK issue 6234299.
