[Closed]Grid returning empty string for a cell with value 0
I have a grid with a NumberField editor for one of the columns. When I enter 0 in the cell it renders correctly but the datasource contains an empty string (""). I am using Ext1.1 rc1 then I switched back to the old version Ext1.01a and it works just fine. Is this a known bug in rc1? Is there a work around. I tried searching the forum but turned up nothing. Can some body throw some light on this one.
