Feeds importing unique nodes over and over I'm trying to import events to a calendar from an external ics..
I installed the Calendar module with the Feeds module. Unfortunately it creates the whole time new nodes. Even if the UID is unique (mapped to field field_gimme_uid) in the node. Update nodes is setted 'on'. I have checked everything but everything seems alright. The unique field is correctly imported (and the same for multiple nodes)..

I have a contenttype "Evenement" with the following fields:


Evenement (title)
Datum (field_event_date) Date
Gimme-UID (field_gimme_uid) Text


I have a feed that maps the ics import to the nodes

My ICS that I use to import can you find here

Why is it importing the whole time the same nodes?
My bad! The "Unique" option in the feeds module isn't working without the module "Field Validation". I added an unique rule to the contenttype "evenement" and now it works like a charm!
