title: how to get value of a field in fields_view_get?
body: <p>I want to get a value of a field in fields_view_get method in openerp 7.0. </p>
  
  <p>I tried the following:
  1- send the value of the field in the context attribute as following:</p>
  
  <pre><code>&lt; field name="employee_id" context="{'employee_id':employee_id}" /&gt;
  </code></pre>
  
  <p>and in the fields_view_get I get it as following:</p>
  
  <pre><code>print "employee_id in the context value is  %s"%(context.get('employee_id', False))
  </code></pre>
  
  <p>but it always the the context.get(...) returns False. so I tried the following:</p>
  
  <p>2- on the onchange method of the field I send the value of the field in the context as following:</p>
  
  <pre><code>def onchange_employee_id(self, cr, uid, ids, employee_id):
  return {'context': {'employee_id': employee_id}} 
  </code></pre>
  
  <p>and in the fields_view_get I get it as following:</p>
  
  <pre><code>print "employee_id in the context value is  %s"%(context.get('employee_id', False))
  </code></pre>
  
  <p>but also the same thing always the context.get(..) returns False.</p>
  
  <p>How can I get the value of a field in fields_view_get function ?</p>
