I think thats because the current page is cached in the navigation  
object. So it isn't reinitialized.

Bind an action method to the tabitem and refresh the ivars you want  
to refresh?


If you always want to refresh you can do this:

   - (NSArray *)myCalls {
     if (self->myCalls == nil)
        .... calculate them
     return self->myCalls;
   }

   - (void)sleep {
     [self->myClass release]; self->myCalls = nil;
     [super sleep];
   }

Its not exactly recommended because accessor methods should not have  
side effects, but its used that way in a lot of places nevertheless ...
