title: openerp - wizard should not close on button click
body: <p>I have added a button on wizard "Change Standard Price(stock.change.standard.price)". It is accessible from Products-> Procurement Tab -> "- update" link.</p>
  
  <p>As soon as I click on that button wizard get closed though I don't want to close it. It should be close when I click on "Apply" or "cancel". </p>
  
  <p>Here is the code:</p>
  
  <p>Button:</p>
  
  <pre><code>&lt;button string="New Cost" name="get_price" type="object" class="oe_inline"/&gt;
  </code></pre>
  
  <p>Method:</p>
  
  <pre><code>def get_price(self, cr, uid, ids, context=None):
      cost_price = 100
  return {'new_price': cost_price, 'nodestroy': True}
  </code></pre>
  
  <p>I am returning nodestroy too as I read it will for not destroying wizard.</p>
  
  <p>Am I doing something wrong?</p>
  
  <p>Thanx in advance.</p>
