[support] Sorting a view on a non database field

[Anthony Malkoun]

Hi,

I have a view where I've written my own views field handler that 
basically shows a check or a tick based on a bunch of other conditions.  
Is there a way I can make this sortable?  I think that I'm stuck as 
views can only sort on database fields from my research so I'm limited 
to maybe some sort of dummy placeholder field that will be updated based 
on my condition.

Anyone know a better way?

Thanks,
Malks.
