dataTable inefficiencies - hit db twice on each request

Hi,

 

I noticed that if preserveDataModel=false, then JSF will attempt to fetch
the table data twice - once during the apply request values phase, and once
during the render response phase. It doesn't do that if
preserveDataModel=true, but then I don't get proper sorting in the table.

 

Hitting the database twice on every request is not acceptable - so is there
a way around this?

 

Thanks

Yee

You can simply set your backing bean as session-scoped.

Also take a look at:
