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`
You can use the option GONE instead of INVISIBLE.

A good option is to define it in XML as GONE and when you need it make it visible.

```
           <ListView
            android:id="@+id/links_bar"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:visibility="gone" />

```
