>          Components: mx: ComboBox, mx: DataGrid, Spark Components

> We have a Flash Builder project that contains a module that will be loaded later through an AIR application, there are several screens on it, in one of them there is a spark spark dataGrid with multiple columns GridColumn. 
> Some of these columns have associated itemRenderers these itemRenderes are created in separate files based on elements GridItemRenderer Spark, within them there is a spark ComboBox component when the user selects a value from comboBox, GridItemRenderer itself updates the value of "data" with the new selected value.
> The problem comes when you scroll at the datagrid, the values of these columns "dance" from line to line; we´ve tried to solve this problem using a itemEditor and a itemRenderer at the columns but in initializing itemEditor gave us null pointer to initialize the moduleFactory the defaultItemEditor.
> Finally we had to change the dataGrid and use mx components to achieve properly run our screen.
