Store.findExact throws error in an Infinite grid in Ext4.2 beta

[PriyaL]

we upgraded to Ext4.2 beta. In the case of an infinite grid with buffered store, store.findExact method throws data.findIndexBy not a function error. The same was working fine in Ext-4.1.
Found that in 4.2, buffered store data is LruCache, which was Ext.util.MixedCollection in 4.1.

We need a way to find records that are in view.Any idea on this?

I checked the thread. It was mentioned that you have merged a fix that allows to find the records that are in view. Where is the fix, which method should I use? I did download ext-4.2.0.265-beta build mentioned in the thread.

We want to find records that are in view. We were using store.findExact method in ext 4.1 and want something similar in 4.2.
