have a strange problem.
i have a big grid about 30 columns and 1600 items.
but thats not enough the grid has to different column-definitions and to speed it up i work with multiple stores.
to switch between the column-definitions and the stores i use grid.reconfigure() and this works really fine.
the problem i have now is, that firefox does not update the grid header with the sorters that are defined in the reconfigured store.
chrome does highlight the sorter in the header.
my first solution to this was to call store.sort() after every reconfigure. but in this case the browser does the whole grid render stuff twice and that is a massive problem by our customers.
Do you have any suggestions, is this a bug (couldn't find anything helpful).
btw: i use ExtJS 4.1 and also have tried 4.1.1 - it's the same problem.
