Giving a map with ID to player

Hi there, I am making a mod which creates special maps. Now I have created a map, but I want to give the map to a player. I used this code:

Code:

        ItemStack newstack = new ItemStack(Material.MAP);
        newstack.setDurability(newmap.getId());
        p.getInventory().addItem(newstack);

However, sometimes I cannot pick up the map, and when I give it to other players, it is buggy. Can someone help me on how to do this?

Thanks,

Nevermind, I solved it by changing it to:

Code:

ItemStack newstack = new ItemStack(Material.MAP,1,newmap.getId());
p.getInventory().addItem(newstack);
