Hi, I had a new state to Sale Quotation, and two other states to Purchase quotation. Now I needed to when changing the state in Purchase order to automatically change the state of Sale quotation from draft to my new state.

I don't have any idea if this change is in the file mymodule_workflow.xml or in mymodule.py, I've tried in both but nothing...

In mymodule_workflow.xml I've tried this:

....
    <record id="trans_receivepq_waitingdocs" model="workflow.transition">
        <field name="act_from" ref="sale.act_draft"/>
        <field name="act_to" ref="act_waitingdocs"/>
        <field name="signal">purchase_received</field>
    </record>
....

and after I've tried this:

   <record id="act_rfq_received" model="workflow.activity">
        <field name="wkf_id" ref="purchase.purchase_order"/>
        <field name="name">received</field>
        <field name="kind">function</field>
        <field name="action">write({'state':'received'})</field>
    </record>
    <record id="act_po_recpq" model="workflow.activity">
        <field name="wkf_id" ref="purchase.purchase_order"/>
        <field name="name">po_recpq</field>
        <field name="kind">subflow</field>
        <field name="subflow_id" search="[('osv','=','sale.order')]"/>
        <field name="action">write({'state':'waitingdocs'})</field>
    </record>
    <record id="trans_sent_received" model="workflow.transition">
        <field name="act_from" ref="purchase.act_sent"/>
        <field name="act_to" ref="act_rfq_received"/>
        <field name="signal">purchase_received</field>
    </record>
    <record id="trans_sent_received_so" model="workflow.transition">
        <field name="act_from" ref="purchase.act_sent"/>
        <field name="act_to" ref="act_po_recpq"/>
        <field name="signal">purchase_received</field>
    </record>

But nothing happens, no error no nothing...

Then I've tried like this in mymodule.py :

def contracts_received(self, cr, uid, ids, context=None, default=None):
    so = {}
    soid = {}
    if not default:
        default = {}
    soid = default.get('asd_pquotation_id')
    so = self.pool.get('sale.order').browse(cr,uid,soid)
    so.write(cr, uid, ids, {'state':'waitingdocs'})
    self.write(cr, uid, ids, {'state':'received'}, context=context)
    return True

and in mymodule_workflow.xml :

<record id="act_rfq_received" model="workflow.activity">
    <field name="wkf_id" ref="purchase.purchase_order"/>
    <field name="name">received</field>
    <field name="kind">function</field>
    <field name="action">contracts_received()</field>
</record>

This way I've this error :
