In **init** method of my ModelForm, I set type of field:

```python
self.fields['gwlist'] = forms.ModelMultipleChoiceField(label='List of gateways:',
    queryset=Gateway.objects.all(),
    initial={'gwlist': initial_list})

```

I want to set some gateways selected in whole gateway list, when form is showing for user. But I can't.

Does it possible?
