How to use comparator from rich:column

[Radu Mircea]

Hi ,

I am trying to implement sorting between two colums the behavior is something like when values from first column are equal then sort after second column. I was trying to do this using sortPriority but this affect GUI behavior when user clicks on a header column's if the priority is not the biggest one the sort is not done, this is not ok...Could i achive the same "negative" (in my case) behavior if i use comparator ?

Please if you know some examples where this property is used.... give me a hand !

Regards,

Radu
