Hi,

I have a content profile 'Person'. This is a content profile which is mapped to an user by using the field 'Authored by'.

I am updating the Person nodes. I do not specify a mapping for the field 'Authored by'. However, when updating the nodes the field 'Authored by' is overwritten (empty). For CCK fields the data is not overwritten when I not specify a mapping. I know the setup for CCK field is different and I cannot expect something that works for CCK fields is also working for Node fields.

When I create a mapping column for the field 'Authored by' and I map this field (for nodes who have an author I specify the username for nodes with an anonymous author I do not specify a value), I get the message: 'This user already has a content profile of this type. You can only create one profile per user.' for the nodes which already have an author.

Any clue how to fix it? I already applied the patch from: https://drupal.org/node/874422#comment-6233512
