i implemented a ListModel with cache and used with autopaging feature as documented:
but when i got to have a totaSize of 1.7 milion record the listbox hang like forever, even if my custom listbox loaded 50 of them and shows only 20 of them!
using jvisual vm i discovered that Listbox just create totalSize of Listitem then Iterate through them all!!!
then i discovered someone else fuond this scalability bug and was forced to to manual paging!
i even tried Rended On Demand... with no luck, even with ZK EE
just create pageSize of Listitem then reuse it when page change!
