model report - role attributes unavailable

Hi guys!
In my report model project Im trying to use the attributes of an entity.
This entity has (a number of) subroles coupled to it, which all are available
in the ReportBuilder-app once I drag any entity ground-level attribute on to
the canvas.
Unfortunately Im not able to put out the attributes in the subroles even
though they are visible among the ReportBuilder entity-props so they are not
hidden or anything.
I can drag these role-attribs out, but the mousepointer changes to that
forbidden-sign-thingie when I drag them out. For some reaseon RB does not
want to cooperate here, and Im not able to figure out why.
Anybody recognize this and care to comment?
DavidI found the reason; the cardinality was set to optional-many in both
directions of the role.
changing it to be optional-many/optional-one resolved this.
Hope this helps someone else!
