[flexcoders] DataGrid - ItemRenderer BUG on scrolling.

[alom17959]

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... THank you , by the way, sorry for my 
english, im from mexico, lol :P
