[Magritte] MAToOneRelationDescription explanation

Hi: I'm a bit confused using relationships between objects in Magritte. Let's start with MAToOneRelationDescription. I've a Contracts system were each contract have 1:1 Relation with Suppliers (another collection of the system), then on the form to add contracts, on the place of Supplier I wants to show a combo with, for example, all the suppliers names loaded on the suppliers collection, to select one to use in the current contract. Very common need I think (Is the way I used to do with Mewa). But trying with different options (not found much doc about each possible method to use on MAToOneRelationDescription) I get a "create" button than, certainly, is not what I need and really not understand the fundamentals of this button on a single 1:1 relationship. Any clarification about this topic, examples, documentation, etc will be greatly appreciated. BTW, I'm using Seaside 3.0 with installed on Pharo rc2 with the Configuration provided by Dale.
