[Grégoire Weber]

We at Padua use a fix that avoids breaking backwards compatibility
with old products using string actions and not expressions (the head 
of archetypes is an example for that).

Backwards compatibility changes:

CMFCore/ActionInformation.py, line 128

    def getActionExpression( self ):
        """ Return the text of the TALES expression for our URL.
        """
        action = self._getActionObject()
        expr = action and str(action) or ''
        ##### OLD: expr = action and action.text or ''
        if expr and type( expr ) is StringType:
            if not expr.startswith('python:') and not
expr.startswith('string:'):
                expr = 'string:%s' % expr
                self.action = Expression( expr )
        return expr

In CMFCore/Expression.py add to class Expression (Persistent):

    def __str__(self):
      return self.text
