Actually, my mistake, it works ! I was running in debug and it messed up my output. Thanks a lot in deed Tom.
btw, there is a good article on http://www.adobe.com/devnet/flex/articles/e4x_04.html that does the same thing in a slightly different manner.

Unfortunately this does not work. I have tried the following : public function myLabelFunction(item:Object, column:DataGridColumn):String { var field:String = column.dataField; trace("val=" + column.dataField); trace("val=" + item.toString()); if (field != null) { var foo:Array = field.split("."); trace("\n>>>>>>"+item[foo[0]][foo[1]]+"<<<<<<<\n"); } return item.epar_document.id + " " + item.epar_document.rev_number; } but I get an error (not such variable epar_document)... too bad. Thanks anyway.
