Alex Rudyy commented on QPID-7288:
----------------------------------
Keith,
I addressed your first and second review comments in commits
[https://svn.apache.org/r1749902] and [https://svn.apache.org/r1749912]
accordingly.
I agree with your third comment. Updating of huge grids could be too slow. The
implemented solution is a workaround allowing to update rows smoothly without
their complete recreation. It looks like improving performance might result in
increasing of complexity of existing code. Perhaps, a different approach should
be implemented like building our own pagination extension for dgrid.

> Key: QPID-7288
> URL: https://issues.apache.org/jira/browse/QPID-7288
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Reporter: Keith Wall
> Assignee: Keith Wall
> Fix For: qpid-java-6.1

>
> QPID-7215 changed the VH tab to use the dgrid to display the connections
> associated with a virtualhost. Unfortunately, the grid flickers in an
> unsightly/distracting way during refresh..
> Lorenz reported:
> There are at least two usability issues
> ordering by clicking on the headers is broken. the orderBy clause contains
> "NaN"
> because of the way dgrid refreshes itself by clearing the table and then
> rebuilding it the surrounding container resizes eventually resizing the page.
> this will move the scrollbar up the page so when the grid is rebuild the
> viewport is set to the top of the table making it virtually impossible to
> view the bottom of the table or anything below it.
