Hi all,

I'm new to WO and I would like some help to fix an issue in a many-to-many relationship. I have to entities, Clients and Contacts. Contacts has a nice "Profile" component with a WOBrowser that lists the Clients to which you can connect the record. The submission of this page immediately saves the editing context. It work's fine and data is correctly added to db's but, when I switch to check the "Client" profile (where I should see the newly added Contact), the record is not there. If I quit and restart the application though, the changes are reflected and everything is ok. I assume the problem has to do with the fact that I've missed the part where I also update the Client.contacts array in memory (even though the db's are already populated with correct data). But I'm confused on what should I do. Should I use the addObjectToPropertyWithKey or addObjectToBothSidesOfRelationshipWithKey when saving the editing context? Even if I'm just updating a record and not adding? Or should I simply refetch everything so that the new configuration is loaded?

Ok ok...I know... I'll find out that the answer was as stupid as possible :-) Please don't blame this newbie...

Thx, Ric _______________________________________________ webobjects-dev mailing list | email@hidden Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/webobjects-dev Do not post admin requests to the list. They will be ignored.
