Hello,

It's also possible to do this in a property sheet using a trick similar 
to the Object_getSizeColourReference example in 
http://www.erp5.org/HowToUsePropertySheets

Use a property sheet like this one:

class FunkyTitle:

     _properties = (
         {   'id'          : 'title',
             'type'        : 'string',
             'default'     : '',
             'acquisition_base_category'     : (),
             'acquisition_portal_type'       : (),
             'acquisition_copy_value'        : 0,
             'acquisition_mask_value'        : 1,
             'acquisition_depends'           : None,
             'acquisition_accessor_id'       : 'getTitle',
             'acquisition_depends'           : None,
             'alt_accessor_id'               : ('Base_getFunkyTitle', ),
             'override'    : 1,
             'mode'        : 'w' },

     )

What's important is the "override : 1", this will override the default 
getTitle accessor.

I think this approach won't work if XMLObject_type_based_title patch is 
applied, because the patch sets a getTitle method on the class, and only 
dynamic accessors can be replaced.
