You have to specify the dataField of the DataGridColumn of the column in which you have the ComboBox itemrenderer behind the current object: cursor.current.[dataField value]

The current statement refers to the complete object in the original ArrayCollection, to get the value you should refer to the correct attribute from that object…

Hope this solves your problem.

Now I need to catch for each row of the datagrid the selected value of the combobox when the user clicks on a button external to the datagrid.
How can I do this?
I have tryied with the cursor but how can I catch the combobox value?:

while( !cursor.afterLast )
{
// Access each column field like: cursor.current.MyFieldName
mx.controls.Alert.show(cursor.current.????)
// Obviously don’t forget to move to next row:
cursor.moveNext();
}

I have found a gotchya in this though, if you use “disableAutoUpdate” before entering the lopp, when removing items, the cursor does not get updated properly and you will exit the loop early.
