Question: In a form I've 3 subgrids with N:N relation which point on the same entity (but don't display the same view).

When I create only 1 of theses subgrids, I've correctly the addbutton and I can add records in my subgrids.

But when I've more than 1 subgrid, the + button in each subgrids (and all the button like edit etc which are in the subgrid's command bar) are hidden...

I guess that the problem is that I've 3 times the same N:N relations for my subgrids in the same form, but I don't figure out why it's a problem and I don't know how can I make the + buttons visibles...

Could you help me?

Answer: 
Hide it - 

```
v.findViewById(R.id.links_bar).setVisibility(View.GONE);

```

show it again with -

```
v.findViewById(R.id.links_bar).setVisibility(View.VISIBLE);

```

or `numero_info <=0` is never `= true`
I assume you want to show/hide views from the layout. 

You have correctly used setVisibility() method but FYI there are 3 attributes you can use with it:

* View.VISIBLE - which makes item visible and stays there in layout
* View.INVISIBLE - which makes item invisible but stays there in layout
* View.GONE - whic makes item invisible and remove it's presence/space from layout.

So if you would want to complete hide the view then use GONE otherwise INVISIBLE.
