Problem with Rich:ExtendedDataTable with more than 100 rows

[deepaksm]

Hi ,

   I am new to JSF, i am using richfaces3.3.2.CR1 (Chose this version coz i was in-need of a table which would provide both horizontal and vertical scrolling, found it in this version ), i am currently using <rich:extendedDataTable> to display the content of a table from a list, My table(list) has 25 columns and 1500 rows. When i display around 10 - 20 rows at a time along pages with rich:datascroller It works perfectly fine.

But when i try to display around 500 rows at a time , it tends to hang and the page never comes up . I have also tried ScrollableDataTable and DataTable but i am facing the same issue in all these components , i am unable to figure out the issue . Do we have any other component in JSF which supports more number of rows along with providing vertical and horizontal scroll features ? My only requirement is to get rid of the pagination or have least number of pages . Can someone pls help ?????

Scrollable dataTable should works fine with rows limited to 20 rows for example. Then it will fetch the data for others via ajax. And extendedDatatable loads all the data to the client. So in case you have much rich:components (calendars, toolpits, inplaces.. and so on) it will affect the performance much because of too much of js objects created.

In the past I have written  about the problem and possible optimizations in specific case of calendar component usage http://www.jroller.com/a4j/entry/richfaces_calendar_component_shared_calendar

IIya , Thanks for the reply.

Have replaced ExtendedDataTable with ScrollableDataTable as suggested , It is taking quiet some time to fetch and synchronize the data but it should serve the purpose for now. Thanks a lot for your timely help
