[4.0.0] performance problem caused by store.removeAll() not clearing prefetchData
[4.0.0] performance problem caused by store.removeAll() not clearing prefetchData
In IE indexOf is very slow, and if we add lot of data to store before, then after store.removeAll(), the replace call done against existing data in prefetchData is making IE spin so popup a warning asking the user if want to kill the script.
Thank you for reporting this bug. We will make it our priority to review this report.
