I think the problem is that collection views make a copy of the 'prototype' view for each view they create. They do this using archiving/dearchiving, and they have no way to make connections of the sort you've made because they are application dependent.
Have a look and see if there is a hook you can use to manually remake the connection as each view instance comes into being. Otherwise you could change your design a bit. For example, I have a class of formatter that scales its values according to a scaling factor set in each document. Each formatter instance picks up this common setting from a class variable in its own class, and as each document is activated and deactivated, it sets the appropriate class-level value. That way each formatter doesn't need to know about documents, only its own class. The only gotcha with this is that when the class setting changes it needs to tell the formatters to refresh, which is awkward as they are not views and do not have a connection to the view they're attached to. So I added a back-connection to the immediate textfield to deal with that - that connection should be OK as it's internal to the copied collection view instance. --Graham On 31/05/2010, at 9:45 AM, Rainer Standke wrote: > Hello, > > I have a custom formatter that needs to to look up a default value based on > the current document.
