Unanswered: Extjs Grid scroll dons't work after application kept insert and delete record.
I am developing an application using Extjs 4.0.7.
For reasons, I need to add and delete record to a grid very often(maybe few times per second).Scroll bar for the grid works in the begin, but doesn't work after my application kept adding and delete record to the grid store.
Following is code to add and delete record to grid store
function insertItems(store, records)
if (store.count() > 150) store.removeAt(0);
Is that a extjs bug? Do any one have any idea or solution for the problem?
