Is myComboValueProperty the id of the combobox(Example --> <mx:ComboBox id="myComboValueProperty" )? I am having problems getting to the new value that has been change in the combobox, because the dataprovider does not get updated automatically. The dataprovider of the datagrid contains the old value for that column even though the itmerenderer cb box has changed its value. Thanks
