    Default Grid with buffered store and grouping feature

    Ext version tested:
    • Ext
    Browser versions tested against:
    • Google Chrome Version 48.0.2564.116 (64-bit)

    • I am trying to combine a buffered store with the grouping feature of the grid. When doing so I get an exception : Uncaught Error: Cannot reconfigure grouping switching between buffered and non-buffered stores

    Steps to reproduce the problem:

    The result that was expected:
    • The grid should be displayed and the rows should be grouped.

    The result that occurs instead:
    • The grid is empty and there is an exception in the console.

    Does this mean it's also fixed in 6.x?

    This appears to still be broken in 6.2 and 6.02 (try out the Fiddle).

    Seems to have something to do with binding versus direct assignment of the store.
