If you are using OpenERP version 7, try this way of including JS files.

In the _openerp_.py part in the link, look for this part:

'data': ['mydisplaydb.xml'],
'js': [],

Put the name of the js file here (mydisplaydb.js), and replace the xml file call for data so it should look like this:

'data': [],
'js': [mydisplaydb.js],

So basically, instead of using the XML file and calling the JS file from there, you can directly link it in the _openerp_.py manifest file.

I used to use this method to call JS files in OpenERP 7. Also, can you give an idea of what you are looking to put in the top right corner? We can explain what is necessary in the JS file more clearly.

Let me know if you need more help with this.

Edit:

Ok. Now, remove the xml file completely. In version 7, you do not require the XML for JS. Only keep your JS file and write only the following in your JS file. Your __openerp___.py manifest file must only keep the JS file as a dependency, there should be not xml mentioned in it.

openerp.mydisplaydb = function (instance)

{

instance.web.UserMenu.include(
    {
        do_update: function ()
        {
            this._super();
            alert("hello");
        }
    });

}

Do not keep anything else in your JS file. Refresh your browser and see if you can get an alert. Please note, in the first line, openerp.mydisplaydb, the name must exactly match the name of your module.

If this doesn't work, we'll go step by step and start over.
