rich:extendedDataTable super slow

[eligriv]

Hello everyone.

I just switched from rich:dataTable to rich:extendedDataTable and the performances are terrible.

After all my java process, the page needs at least 30 more seconds to load entirely, and my site is deployed on my local jboss, and it happens even when there is no data !

I use richfaces 3.3.1.GA, seam 2.1.1.GA (i'm not sure if it's relevant, but seam is not ultra fast either)

Here's a portion of my table :

<r:extendedDataTable id="transactionList" value="#{transactions}" var="tr" rows="100" height="600px" rowClasses="deal_ligne_impaire, deal_ligne_paire"
 selectedClass="deal_list_selected_row" headerClass="deal_list_header">

And then 40 rich:column.

What am i doing wrong ? How can i improve, in any way, these perfs ? I really like the features of this tag.

Thanks

Hi,

You can turn off context menu; this should increase performance significantly.

Is there a way to disable the possibility to drag and drop the columns ?

for example, a property such as, enableColumnsChangeOrder=false ?

seems you should comment and add your vote there https://jira.jboss.org/jira/browse/RF-5086

I have turned off the context menus, drag and drop etc, anything I could and the performance is now acceptable and almost as fast as the regular datatable.
I am not totally excited about the approach I took though and it needs to be cleaned up but the process is this:

1. get the source code for the component
2. copy it into your web application as is package and all
3. comment out a bunch of code including the parts that render context menus
4. test to make sure the component still works

The right way to do this would be to properly subclass the renderer and abstract renderers and register your new renderer as the renderer for the table. The problem is that their abstract renderer has a lot of private code that makes this impossible, you end up having to copy their code and alter it.

Another option would be to copy their cdk folder to a new folder and make your changes there. Thereby creating a new extendeddatatable of your own based on theirs.

To the other poster, how do you disable the context menus? I don't see a property anywhere to do that.

look at the lates rf-manual, there is a property enableContextMenu.

Hello,

I hope you can help me to fix a problem.  I Have a rich:dataTable wich is super super slow.

In fact, when i'm filtering by a column, the time is spent on the server ; the whole page is reloaded many times : all other components of the page are reloaded by calling out the database. I don't know why

Can you help me please ?

I'm using Richfaces3.3, JBoss 5.1 and Jboss-Seam 2.2
