#1 below sounds way fishy. For performance reasons List based controls

1 or 2 more. As the user scrolls, this set is re-used. What you have done
is bypass this completely by making ALL rows visible and thus 1350 instanc

retrieved from the server. Each record has 5 fields, and I am using one very
simple custom renderer. The grid doesn't seem to be able to handle these many
records, and throws the following error:

I was this days extending the component to do the same Excel funcionality.
I conclude that using itemRenderers that extends UIComponent ends
downgrading
the performance of the grid. So I recomend to extend
AdvancedDataGridItemRenderer
although probably you'll have to sacrifice all the displayobject
I have an application based on a AdvancedDataGrid control that makes
use of custom editors and renders to in many ways resemble Excel.
Problem I am having is that if the user begins rapidly entering data
