so your library will keep track of elements moved within the dom? currently, i am setting the subscription info on a <div> that is created within a cell renderer. these elements are discarded when the column is moved or sorted. i will try to attach the subscription data to the <div> on level up, but i think i will have to dig into the ext js library to accomplish that.

in the interim, i will switch to using a NonVisualTable and updating the values directly.

thx
