Rendering page regions onload

[Clint Smith]

I have a "dashboard" page in an application that pulls data from several datasources. I would like to enable the dashboard to load each region of the dashboard as an ajax request, so that the dashboard page will renders to the user quickly, and each region will populate asyncronously when it's ajax request completes. Does anyone have advice as to the best way to do this?

Do you need to update the regions of the "dashboard" only once when the page is loaded or you have to upload them periodically when the page is already on the screen?

[Clint Smith]

Only when the page is initially loaded.

Use a4j:jsFunction that will be invoked from


a4j:jsFuction action method should set the right datasource for each regions on the dashboard. (At the begining the region should load empty data). a4j:jsFunction reRender should point to the region(s).

Note: JSF 1.1 is not designed to have simultaneous requests for the same session. Some rand glitches might happens.
