</record>   

</data>

I know I have many errors in wizard code, because I don't know how to it and how I can call the wizard from the button, anyone can help me with this ?

Answer 1

I don't have time now to read all your code, but the button on immo.article.form should have action reference in name attribute, not in string:

<button name="%(action_duplicate_object)d" type="action" string="A string"/>
