Datagrid Itemrenderer scrolling problem

Question

Hi,
I have a datagrid bound to an ArrayCollection. For one column
I have a custom item renderer - which is a textbox.
It works OK except when you scroll the rows and values get
jumbled up randomly.
I'd be grateful if anyone has any ideas.
Thanks,
dan
