I'm experiencing issues with scrolling/displaying/validating/filtering/clicking in a list, using a store with more than 500 items.
I believe the large amount of item displayed within the dataview is causing this.
Are you working on improving performances on this side, or are we stuck to using small amount of items in a store ?
Why would you load 500 objects into your store at once? You should really be using paging on the store / proxy and have your backend respect the pagesize, page#, etc. I would fully expect a store with 500 records to perform very poorly. Think small, light. Just my .02
