Dhiraj commented on DISPL-39:
-----------------------------
Workaround for secondary sorting with display tag:
If the list of objects is sorted from the backend, that sorting is retained
while sorting on other columns.
Limitation of this workaround is that the secondary sort column is fixed.
> Let users sort across multiple columns

> Sorting in the library should support the user sorting
> across multiple columns. A sort from one display of a
> table should be used as input for the sort on the next
> column.
> eg. From the initial table (warning: ugly ascii art follows)
> Name | Dept | Role
> =======================
> Bob | Sales | Manager
> Joe | Dev | Engineer
> Fred | Dev | Manager
> Sorting this by Name gives:
> Name | Dept | Role
> =======================
> Bob | Sales | Manager
> Fred | Dev | Manager
> Joe | Dev | Engineer
> Sorting this by Dept gives:
> Name | Dept | Role
> =======================
> Fred | Dev | Manager
> Joe | Dev | Engineer
> Bob | Sales | Manager
> Note that Fred now comes *before* Joe in the list.
> Implementing this would mean that sorting would work in
> the same way that it does in standard windows list
> views, so would work the way many users would expect.
