I'm new to openerp and using version 7. I'm trying to create a new module using the instructions from the link below:

http://acespritechblog.wordpress.com/2012/05/22/how-to-create-a-module-in-openerp/

But when i try to install the module all i'm getting is "Error occurred while validating the field(s) arch: Invalid XML for View Architecture!" is there a way to debug this? What part of my view is wrong? Everything i did is the same with the link but here is the view XML anyway:

<?xml version="1.0" encoding="utf-8"?>

       <record model="ir.ui.view" id="test_base_form">
