title: How to add a field into an inherited view's tab/page?
body: <p>How can I inherited a view to add a field into the "Sessions" tab ? </p>
  
  <p>e.g : </p>
  
  <pre><code>&lt;record model="ir.ui.view" id="partner_sessions_form_view"&gt;
      &lt;field name="name"&gt;partner.sessions.name&lt;/field&gt;
      &lt;field name="model"&gt;res.partner&lt;/field&gt;
      &lt;field name="type"&gt;form&lt;/field&gt;
      &lt;field name="inherit_id" ref="base.view_partner_form" /&gt;
      &lt;field name="arch" type="xml"&gt;
      &lt;xpath expr="/form/notebook/page[@string='Notes']" position="after"&gt;
          &lt;page string="Sessions"&gt;
              &lt;field name="session_ids" nolabel="1" colspan="4"/&gt;
          &lt;/page&gt;
      &lt;/xpath&gt;
      &lt;/field&gt;
  &lt;/record&gt;
  </code></pre>
  
  <p>This adds a page, but how would I add a field in the page <strong>Sessions</strong> ?</p>
