Hi, your problem it is in the line :

<menuitem name="Boutton" parent="dev_menu_person" id="view_partner_form" action="mymod_form" />

action="mymod_form" must reference in record of type ir.actions.act_window

so add this record :

   <record model="ir.actions.act_window" id="action_mymod_form">
        <field name="name">Workflow</field>
        <field name="res_model">mymod.mymod</field>
        <field name="view_type">form</field>
        <field name="view_mode">form</field>
    </record>   
  <menuitem name="Boutton" parent="dev_menu_person" id="view_partner_form" action="action_mymod_form" />

Thx for your help.

But I have this error : Integrity Error

The operation cannot be completed, probably due to the following: - deletion: you may be trying to delete a record while other records still reference it - creation/update: a mandatory field is not correctly set

[object with reference: res_model - res.model]

In French : Erreur d'intégrité

L'opération n'a pas pu être terminée, probablement à la suite d'une : - suppression : vous avez essayer de supprimer un enregistrement auquel d'autres enregistrements font référence - création/modification : un champ requis n'a pas été correctement rempli

[objet ayant pour référence : res_model - res.model]

But my buttons do not appear :(

Victorien
on 6/12/13, 2:06 PM

many errors in your code. the record form should be type ir.ui.view and not ir.actions.act_window because menuitem name="Boutton" should be reference to record action and not record form.

in your model mymod add defualt state to display first button _defaults = { 'state':'new',}

and others...
