ExtendedDataTable and Grouping

[alibsd]

Hi,

It seems that ExtendedDataTable groups the data which it is showing without the help of its backing bean.
This method of grouping is not suitable for large amount of data (data came from Database).

It is possible to take the control of this grouping and do this grouping in the backing beans?

yes. Just extend its dataModel and control the grouping on your own. data model usage sample (for true paggination) shown at richfaces-demo.

Hi ilya

I've read the sample for rich:extendedDataTable, in that sample,
the value of rich:extendedDataTable has been bound to an
ExtendedTableDataModel, neither this class nor ExtendedTableDataModifiableModel has methods for handling grouping.

What kind of DataModel I should extend for handling grouping?

Thanks for your help.
