Problem:

Ext JS version: 4.2.2

I am using 'queryBy()' function on the Store to retrieve an array of records that match a certain filter/criteria. This method returns me a 'MixedCollection' of records. When I pass this mixed collection into the remove() method of the Store, its not working.

Temporary Solution: If I convert the MixedCollection into a simple array of records and pass into the 'remove()' function, it works fine. I am not sure if this is a bug but if Ext can support the functionality of passing a 'MixedCollection' returned by the Store's 'queryBy()' method into the 'remove()' method works, it would be awesome.

thanks,

Vijay.
