ListView Sorting based on a field

hi all,

I have a listview whose datasource is association.

Now if i see carefully the order in which the items are appearing is based on the oder in which they are created.

I want to do this over another field which is an Integer(for simplicity sake) which a field in this Entity over which ListView is running

I have 1 or ways but they are workarounds in my view(like recreation of the instance based on this field)

Since this is a UI matter i was wondering if this can be achieved using something else? like java script from the ListView widgets listeners?(shot in the dark i know)
