If I immediately remap JSON on the server, do I need to use remapColumns or the permutation variable?

If you want to see my question laid out in detail, see this post I just put on Stack Overflow.

Here's my synopsis:

With each column tweak, I save the new column model to the server, for that user, and immediately start mutating the JSON to align with the new column order for that user's ajax requests. In this scenario, do I still need the remapColumns function or the permuatation variable?


As it stands, since I've already 'mutated' the JSON for successive ajax requests, it is then being mutated a second time by the "perm" array that my "done" function of the column chooser sent into the remapColumns method.

After a user has used the column chooser (or has performed a column drag-n-drop) is there a way I can clear out the permutation array?

Is there a way I can adjust things so the user doesn't have to refresh their page to start using the new column order?

I've seen Oleg's recommended way to persist settings (but, I had already put this solution in place)

What I think I need to do, is use remapColumns in the normal manner, initially, so that the local data already in the grid, along with it's headers, are properly re-organized.

Then, I think I need to call remapColumns a 2nd time, passing in a plain permutation that informs the grid that incoming ajax requests can be left alone.. a cell-data only permutation of [0,1,2,3,4] so that it does not affect try to map the JSON (since the server is already doing it).  I'm not sure how to do this, however.
