ExtendedDataTable : how to group by a pre-defined column?

[pomc]

Hi, anyone know how i can load the extendedDataTable with a pre-defined group column?

Currently, user has to select "group by this column" to group by a column in the table. i try to use groupingColumn attribute of the extendedDatatable by passing in a column Id, but it gives me error (It says it must pass in a UIColumn instead of a string)..

Please advise....
