I have added a many2one field to a view. Now I want to restrict the limit of entries and show a pager.

I found the question "How set limit for number records of x2many?" and the answer works. The problem is now that if I set the limit to e.g. 2 then only two items are shown but no pager is used. Do you know how to add the pager?

Or do you know an existing module to limit the entries in x2many fields?
