life cycle of TreeGrid, ListGridFields and SortNormalizers

I have a conceptual question regarding a TreeGrid, ListGridFields and SortNormalizers. The scenario is I have a TreeGrid that is refreshed from time to time (new data appears from the fetchData()). I have my ListGridFields instantiated once and I reuse those ListGridFields with every TreeGrid.fetchData().

So with every fetchData() I am trying to add a new SortNormalizer to the same field before the TreeGrid.fetchData() is called, so that the results coming back are sorted properly.

Everything works fine until I try to add a different SortNormalizer to the same field in which I added to the first time.

Does this sound correct? Because my SortNormalizer works the first time, and then it does not work there after?

You can change the sort-normalizers applied to a grid at runtime via the "setSort()" API.
You can change the filter criteria via "filterData()" or "fetchData()". You can also force a re-fetch on the same criteria via "invalidateCache()".

None of these requires you to change the set of fields for the grid of course.

Hope this helps
