I had a similar problem like this. Before the if statement where you are checking if the value is not null, set this.text to "". This has worked for me in the past so give it a shot.

Hi, Im Aldo, and i appreciate ur help guys !. First of all, im using a conventional datagrid, the info comes from a webservice, weborb of php, the problem appears only if i create an item renderer component and use it, if dont, nothing happens, everything looks good and pretty, scrolling doesnt affect anything, but as soon as I write and compile something like this: <mx:DataGridColumn headerText="Saldo" width="50" dataField="saldo" itemRenderer="components.mostrador.atencionClientes.renderer_saldo"/> when i scroll the screen goes bad. and like i said, if i dont use the itemrenderer option, everything works fine. So, i start to thinking that my itemrenderer was bad, and i checked and double checked my code and seems to be fine. Im sending part of my code, its really simple, and images of the screen with the glitch...
