ListGrid grouping without DataSource

[thalles]

Hi all,

Is it possible to do grouping in a ListGrid without setting a DataSource?

If I'm setting the data with "setData" and then group the records, I'm getting this exception: "can't getSelectedState without a DataSource with a primary key field set". Although the grouping is correctly display.

Thanks in advance!

Bye thalles
