Looking at you code it appears you are just missing a labelFunction on
the resource.num column. You cannot access nested object properties
with just the column name. Try this:
public function resourceNumLabel( data : Object ) : String {
return data.resource.num;
}
Add the above function as the labelFunction property of the column.
<mx:DataGridColumn columnName="resource.num"
labelFunction="resourceNumLabel" headerText="A"/>
