  &lt;openerp&gt;
  &lt;data&gt;
  &lt;record id="cym_form" model="ir.ui.view"&gt; 
  &lt;field name="name"&gt;Import Bank Statements&lt;/field&gt;
  &lt;field name="model"&gt;account.bank.statement.import&lt;/field&gt;
  &lt;field name="priority"&gt;1&lt;/field&gt;
  &lt;field name="arch" type="xml"&gt;

              &lt;field name="modules" widget="one2many_tag"/&gt;
  &lt;/field&gt;
  &lt;/record&gt;
  &lt;/data&gt;
  &lt;/openerp&gt;
