Not every item has a post-text trigger. You can store the last item and unset the colour in when-new-item:
if not(id_null(pk.last_item)) then
     set_item_instance_property(pk.last_item,pk.last_row,visual_attribute,pk.last_va);
end if;
pk.last_item := find_item(:system.cursor_item);
pk.last_row := :system.cursor_record;
pk.last_va := get_item_instance_property(pk.last_item,pk.last_row,visual_attribute);
set_item_instance_property(pk.last_item,pk.last_row,visual_attribute,'va_current_item');(pk is a package spec)
Lists are always a problem because the when-new-item doesn't fire when the item is first selected. I once tried to use a FocusListener in a pjc for setting list colours, but even at that level they're a PITA.

Just had a thought...this solution will screw up if the block is cleared and you do set_item_instance_property for a row which no longer exists.
Also, you can remove a row which has been given a specific VA for the current item (eg to indicate a value < 0) and inadvertently apply that VA to the item in the next row in the block. Maybe a pjc solution is the only viable General Solution?
