Need help to set up a wizard in OpenERP 7.0 - button

Question

I'm trying to implement a wizard that will update a form a then (if possible, send a signal to workflow to change status of an object, but that will be for later). I'm trying and trying, but I'm doing something wrong since I get stuck with this annoying error!
ValueError: No such external ID currently defined in the system: processos_uc.reformulate_generic_request_wizard
I've got these two files inside the "wizard" folder:
reformulate_wizard.py:
from openerp.osv import osv
from openerp.osv import fields
from openerp.tools.translate import _
class ref_generic_request(osv.osv_memory):
_name='ref.generic.request'
_columns = {
'reformulation_info': fields.text('Reformulation instructions', help='Instructions for the requestor justification the reformulation needs'),
}
def save_info(self, cr, uid, ids, context=None):
if 'active_id' in context:
info=self.browse(cr,uid,ids)[0].reformulation_info
self.pool.get('generic.request').write(cr,uid,context['active_id'],
{'reformulation_info' : reformulation_info})
return {
'type': 'ir.actions.act_window_close',
}
ref_generic_request()
reformulate_wizard.xml
<?xml version="1.0" encoding="utf-8"?>
<openerp>
<data>
<record id="view_reformulate_generic_request_wizard" model="ir.ui.view">
<field name="name">reformulate_generic_request_wizard.form</field>
<field name="model">ref.generic.request</field>
<field name="type">form</field>
<field name="arch" type="xml">
<form string="Insert reformulation info" version="7.0">
<group colspan="4" >
<separator string="bla bla bla here" colspan="4"/>
<field name="reformulation_info" string="Reformulation info"/>
<newline/>
</group>
<separator string="" colspan="4" />
<group colspan="4" col="6">
<button icon="gtk-cancel" special="cancel" string="Cancel"/>
<button icon="gtk-ok" name="save_info" string="Send to reformulation" type="object" />
</group>
</form>
</field>
</record>
<record id="action_reformulate_generic_request" model="ir.actions.act_window">
<field name="name">Reformulate Request</field>
<field name="type">ir.actions.act_window</field>
<field name="res_model">ref.generic.request</field>
<field name="view_type">form</field>
<field name="view_mode">form</field>
<field name="view_id" ref="view_reformulate_generic_request_wizard"/>
<field name="target">new</field>
</record>
<act_window id="action_reformulate_generic_request"
name="Reformulate Request"
res_model="generic.request"
view_mode="form"
target="new"
/>
</data>
</openerp>
And I didn't forget the __init__.py with the "import reformulate_wizard" in it.
I am calling the wizard from my xml view like this (and I guess that's where I'm getting the error):
<button name="%(reformulate_generic_request_wizard)d" string="Button that calls wizard" type="object" />
In my base folder I'm importing the wizard folder inside the __init__.py:
import parecer
import pedido_generico
import tracing
import wizard
And here is the content of my __openerp__.py (The error might be from the order I'm loading things):

Here is the error message from the server logs.

Any help is more than welcome!

Answer 1

The error message is telling you where the trouble is: you're using an id reformulate_generic_request_wizard that isn't declared anywhere.
Your button should point at the action's id, action_reformulate_generic_request_wizard.
So, try this:
<button name="%(action_reformulate_generic_request_wizard)d" string="Button that calls wizard" type="object" />
