statusbar with clickable option not working for selection field

[Denero Team]

Hi,

we have status field like :
    _columns = {
        'state' : fields.selection( [ ( 'draft', 'Draft' ), ( 'wait', 'Processing' ), ( 'done', 'Done' ) ], 'Status' )
    }

I try to set this field in form view as below
<field name="state" readonly="1" widget="statusbar" clickable="True" />

When I try to click on any statusbar lable, it not works and also reset value of status to null in database.

Can anyone help me to fix this issue ?

Thanks
