hello,

resource_title is not a standard accessor. This is in property sheet 
Amount.py :

     { 'id'          : 'resource_title',
       'description' : "The resource title involved",
       'type'        : 'string',
       'acquisition_base_category' : ('resource',),
       'acquisition_portal_type'   : Expression('python: 
portal.getPortalResourceTypeList()'),
       'acquisition_copy_value'    : 0,
       'acquisition_mask_value'    : 0,
       'acquisition_sync_value'    : 0,
       'acquisition_accessor_id'   : 'getTitle',
       'acquisition_depends'       : None,
       'alt_accessor_id'           : ('_categoryGetResourceTitle', ),
       'mode'        : 'w' },

This means that getResourceTitle accessor is somehow equivalent to
getResourceValue(portal_type=portal.getPortalResourceTypeList()).getTitle()

'operation' is a Category, which is not in resource portal type group.

The question is: do we still need this property definition ?
This property sheet is here since the first revision, I guess it was 
added because at that time 'title' accessors were not generated for 
categories.
