Andrey Chorniy commented on RF-7272:
------------------------------------
In my case filtering and sorting is external (in DB), but it really doesn't
help - reRendering take time and traffic and that reduce user experience.
I really like the extendedDataTable, but it's really huge (re-rendering takes
much time because of large size of the HTML/javascript
(data-tranfer/client-side processing)
for example for a row with 10 columns and only 1 data-row the size of
http-request (reRender the table) 55091 bytes (could be a bit reduced, but
still around 45000)
extended-data-table.txt (55091 bytes)
extended-data-table-with-menu.txt (206170 bytes)
row.txt (2213 bytes)
It would be really nice to have a possibility to disable Drag-And-Drop and any
other features. so, introducing more parameters like "enableContextMenu"
(enableColumnMove enableColumnResize) - they could be truned on manually by
adding some controls on the page and re-rendering the table in "design" mode)
As well as just looking for the way to simplify/reduce the size
> Sorting in ExtendedDataTable is slow, especially under IE 7

> Project: RichFaces
> Issue Type: Quality Risk
> Security Level: Public(Everyone can see)
> Components: performance
> Affects Versions: 3.3.1
> Environment: Windows XP, IE 7
> Reporter: Arne Könnecker
> Assignee: Nick Belaevski
> Fix For: Future_3.X
>
>
> The rendering of an ExtendedDataTable under IE 7 after clicking on a column
> for sorting is very slow.
> See
> http://livedemo.exadel.com/richfaces-demo/richfaces/extendedDataTable.jsf?c=extendedDataTable&tab=usage
> for testing
> What can improve the performance of such a table? Deactivation of column
> menus? Deactivation of drag & drop functionality? Or is the
> rendering process slow due to not fix column width and height?
