I'm a little strange problem in my grid and not find out why. I have created several subgrid and never had problems in this grid but I'm having a difficult birth. The information for the main Grid is shown without any problem, but the subgrid shows nothing.

That is, he even succeeded in providing php json to the subgrid. I tried to enjoy another subgrid had to work, and I was changing the url, fields, etc. and only when I change the url of the main grid is that it lets me display. Why does anybody know?

```
jQuery("#organismos").jqGrid({
    url: 'model/ministerio/mod_organismo.php',
    colNames:['Cód. Organismo','Data Efetiva','Estado', 'Sigla', 'Designação curta', 'Designação longa', 'Última alteração', 'Alterado pelo utilizador'],

Result in JSON from grid 1:

```

```

Result in JSON from grid 2 when I select a row in the grid 1:
