I modified the expression to
{{{python:portal.portal_directories.members[context.aq_parent.getId()].center}}}
I have problems to get the folder where this content was just created in. For
this statement context.aq_parent.getId(), context is None. Even object and
proxy are None too.
I've also tried to create a new field "id" in the same schema to set it (when
the content is created) to the value I need. In that case, the statement would
look like this
{{{python:portal.portal_directories.members[id].center}}}
but even here id is None.
This expression is assessed in the same transaction that the content is
created, may that be a problem?
Thank you very much.

And documented in CPSShemas/doc/fields.txt (maybe not completely up
to date).
