Description L Martinek 2003-11-12 14:41:07 UTC
Found in build 200311111900, jdk 1.4.2_02.

I executed one JSP three times. HTTP Monitor had
three nodes under Current Records, but when I
selected one of them, no data was displayed. If I
tried to click on all tabs of HTTP monitor, NPE
was thrown.

Hi Libor,

I just downloaded that build from but it appears to 
be very reduced in terms of functionality? I tried to reproduce it 
with my previous installs but can't.

This problem was due to the integration by Jesse Glick which changed 
the node behaviour (see issue 36479 for more info). I backed out those 
changes. There were some additional problems in addition to this one 
(e.g. if you save a transaction, all current transactions are removed; 
the component could not start if there were any saved transactions, 
etc, etc). 

When testing that the backout fixed the problem, I discovered one 
remaining issue from the schema2beans update (36882) which prevented 
some tabs from displaying data on some conditions. I modified to have that fix.

Forgot to mark as fixed
Comment 5 Jesse Glick 2003-11-14 11:19:38 UTC
Adding reminder that the reverted changes will probably need to be
reapplied (in some corrected form of course) for the changes covered
by issue #35833, judging by architecture bugs I discovered w.r.t.
threading in this module.

Issue #36479 is probably not related to this at all.
