You may want to sort in the setter:
public void setSort(String abc)
{
if(abc.equals(this.sortColumn))
ascending = !ascending;
this.sortColumn = abc;
doSort();
}
Other than that, it looks correct. It should work. Have you tried some
logging to see what methods are getting called? Also you have
immediate set to false, make sure you don't have any faces messages
(your phases may be being cut short).

};
Collections.sort(users, c);
}
public boolean isAscending()
{
return ascending;
}
public void setAscending(boolean ascending)
{

}
It's calling the "setSort" method on my bean, but it always passes the same
column regardless of which commandSortHeader I click on. I'm completly lost
as to what I've done wrong. Any ideas?
