Editable column's value not getting 'persisted' in AdvancedDataGrid

Question

I have an AdvancedDataGrid (whose dataProvider is a variable being bound from my main mxml file, not sure if this is relevant to my problem ). I'm setting one of the AdvancedDataGridColumn's editable property as true, and when I click on the cell in the UI, it is infact editable. But when I press enter/move to a different cell, the old value returns and the newly entered value is lost. Would anyone have any ideas why that's happening? Do I have to manually change the variable provided in the dataProvider?...I would think that would happen automatically right? I'd appreciate any help!

Thanks.

You should post some code or a simple example. In the most simplest case, the newly edited cell retains it's value after being edited. — Sunil D.
Show some code for your AdvancedDataGrid along with the editable column, especially with your itemEditor. — JeffryHouser
Sorry for the late reply. It's flex 4. It's actually some proprietary code, and I'm not sure I understand it well enough to simplify and post an example here. Sorry for wasting ya'lls time. — iman453

This traces out correct when I edit a field and press enter then click on the button to see trace output:
