tryton client - click on boolean

# inside a model
myfield = fields.Boolean('My Label', states={
						'readonly': ~Eval('active', True),
						}, depends=['active'])

# on form_view one can click a checkbox to set true/false

# there is a menuitem which asigns an action that shows only record where myfield = false, using domain
<record model="ir.action.act_window" id="act_myid">
            <field name="name">my Name</field>
            <field name="res_model">mymodel.model</field>
            <field name="domain">[('myfield','=','false')]</field>
</record>

# on tree_view
<!-- other code-->
        <field name="myfield"/>
<!-- other code -->

# the treeview displays just fine ..when i click on a record, not the record opens, but the myfield checkbox is being set to 'true'
# i would like to open a record instead..

<field name="myfield" readonly="1"/> does not work
