Using checkbox as ItemEditor fails

Question

I am trying to use a CheckBox as an itemEditor inside a
DataGrid so i am doing this:
<mx:DataGridColumn dataField="idDoctoEnvio" headerText=" "
itemEditor="mx.controls.CheckBox" editorDataField="selected"
editable = "true"/>
I read in the developer's guide that this is the way to do
it, so i tried it and to my surprise, it doesn't work, i menan
there is no CheckBox control inside the datagrid, instead there is
a normal text value (true or false).
Any ideas on how to do this? I need the checkbox to be able
to change that property from true to false and viceversa

I reported this problem to Adobe
last year. From your other post, I assume you already got
the upgrade and so I further assume they didn't fix it. Nice to see
they are listening.
Long story short, you can't use CheckBox as an
itemRenderer/itemEditor. It just doesn't work as promised. What I
did was I developed my own CheckBox item renderer class (I put the
CheckBox component inside an HBox so that I could also center it in
the cell). With the appropriate logic, it works fine. I made this
component a long time ago and the source is not on this computer,
but I think the problem was related to the CheckBox not updating
its selected property in accordance with the background data. In my
component, I set the CheckBox's selected value to update according
to the "dataChange" event and on the CheckBox's "change" event, I
called a method to update the data["columnName"] value so that it
matches the CheckBox's selected value. I think this will do the
trick. The code is probably still archived in this forum
somewhere.
