OK! Thats the ticket! It looks like that the *dataField *value for the mxml renderer:
<j:DataGridColumn label="Cargo" *dataField*="cargoContacto"itemRenderer="utils.renderers.CargoDataGridItemRenderer" /> maps to the *labelField *in the DataGridItemRenderer class, not to be mistaken for the label field of the dataGrid Column. a little confusing but glad to know whaich is the right one now!
