The result of $rowUser->groups is a DBIx::Class::ResultSet...so it's a
collection of your "groups", not an actual "group".  You can only call
ResultSet methods on it like, next, and count.  If you want to get to
your actual group object, which is where you can then call
"applications", you need to address the actual result object.  e.g.
my $groups = $rowUser->groups;
while ( my $group = $groups->next ) {
   my $applications = $group->applications;
    while ( my $app = $applications->next ) {
       # doing awesome app stuff
   }
}

Hope that helps.
