[flexcoders] Changing itemEditors of a DataGrid a row basis

[Weyert de Boer]

Hello!

I am trying to make a property grid as seen in other applications in 
Flex. Only I am having trouble to change the itemEditors use by the current
selected row. I am having the following ArrayCollection which consists 
of the class:

    public class PropertyItem {
       [Bindable] public var name: String;
       [Bindable] public var value: String;
       [Bindable] public var type: String;
    }

Now I would like to change the dataField or itemEditor of the currently 
selected column using the onItemBegin-event of the Grid. Only the problem
is that the change is not made. Also I have trouble that it doesn't 
change the binded "value"-property of the PropertyItem instance.

Does anyone know how this can be done? Or even better does anyone know 
some working PropertyGrid. A bit like as shown in the below picture?
