How to un-sort a hiCreateTreeTable?

Hi Everyone,

I've been using some tree tables and they have a built-in ability to sort the data by specified column. By default the table appear as being build with the items listed sequentially. At this time the sort  property is not defined:

myTable->sort is nil. If you click on a sortable column 1 or two times it will sort it either on ascending or descending order, while myTable->sort will become '(colNum t) or '(colNum nil). I was expecting that I can simply feed the original property back to nil and all sorting will be gone or push it out of bounds, but an error/warning is produced:



So my qeustion is how I can restore the ordering of the items in the GUI to the original order? I see that the original filedList is not modified, so this is a GUI trick only. I can imagine adding additional column, feed the item number and either sort on it directly or hide it and trigged the sroting with some other sorting callback on external button or bindkey. Getting a snapshot of the tree, deleting the current one and re-attaching it to the tree table doesn't work, since the table keeps the sorting condition. I am trying to avoid the approach with the dummy column if possible, since it will send me down a road to update a lot of other things and tools that are already attached to the current format.

Is there an easier way to revert back the tree table to the original order of the tree items?
