Empty field in change list

[sunjoomoon]

Somehow, in admin change list, order field shows all empty.. so it is like there is order column shown but all empty column. Below is my admin.py code. Other than this, all functions work well though.

What do I have to look into ?

class FaqAdmin(OrderableAdmin, reversion.VersionAdmin, admin.ModelAdmin):        
    date_hierarchy = 'up_date'
    exclude = ('author','from_date','to_date','up_date','order',)

Stupid of me, having read the doc again I found the mistake made. Here is the thing

I put 'order' field - do NOT add any order field as Orderable adds one in model and admin, just read 5 minute doc.
