Hi,

I'm new in OpenERP web module development and I'm currently trying to make a simple module that just display a button, and if I clic the button I want javascript to write a message in the developper console of my browser.

I am following a tutorial : doc.openerp.com/trunk/developers/web/module/ But it doesn't work, and I'm not understanding what I made wrong.

I have the following files :

web_example
    ├── __init__.py
    ├── __openerp__.py
    ├── web_example.xml  
    ├── static 
                ├── src
                     └── js
                           └── first_module.js

__init__.py is empty

__openerp__.py

 {
     'name': "Web Example",
     'description': "Basic example of a (future) web module",
     'category': 'Hidden',
     'depends': ['web'],
   'data': ['web_example.xml'],
     'js': ['static/src/js/first_module.js'],
 }

web_example.xml

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>
        <record model="ir.actions.client" id="action_client_example">
            <field name="name">Example Client Action</field>
            <field name="tag">example.action</field>
        </record>
        <menuitem action="action_client_example"
                  id="menu_client_example"/>
    </data>
</openerp>

first_module.js

 openerp.web_example = function (instance) {
    instance.web.client_actions.add('example.action', 'instance.web_example.action');
    instance.web_example.action = function (parent, action) {
        console.log("Executed the action", action);
    };
 };

According to the tutorial, this code should make a button in the menu, and if you click the button you get a message in the console.

My problem is that when I try to upgrade my module i get errors :

    AssertionError: No window action defined for this id action_client_example !
Verify that this is a window action or add a type argument.

And here is the complete log :

So my question is What am I doing wrong ? Is there another way to just get a button that trigger javascript action ?

Thanks.
