Re: binding relationship to checkbox
Sorry, I'm obviously being a bit dim here, I have got array controllers for both the categories tableview and the products tableview, As I want to list ALL the categories in the tableview I have bound the name column to the categories. array controller, arrangedObjects, categoryName Then the checkbox column needs to bind to?

Re: binding relationship to checkbox
Sorry, that's what I meant, I would check and uncheck the checkboxes to create/break the relationships, sorry, my fault for describing it incorrectly. I still can't work out how I could bind the checkboxes to create this action?

Re: binding relationship to checkbox
Hi, My application has a tab view as the main view (it might look dated but I can take it straight from the library and it works) In one tab I have a table view that holds the 'master' category list. Here I can add/remove categories. In another tab I have my products list. There is a tableview that lists the products, and then various other items displaying other related data, an image etc. In this tab I have got another tableview that currently has a column for the category name and a checkbox column. I want to list all the categories that exist in this tableview, and select and deselect the checkboxes to create/break the relationship(s) between the selected product and the categories. Am I along the right lines?

binding relationship to checkbox
Hi Everyone, I was wondering if anyone could point me in the right direction for my problem? I'm working on a core data application, and in this issue I have 2 entities, product and category. They have a many to many relationship. In my interface I want to have a list of all the categories with a checkbox column, so the checkboxes indicate if there is a relationship between the selected product and the category. It's along the lines of keywords in iPhoto, so I can set/unset the relationships using the checkboxes? This sounds to me like something that should be doable with the 'magic' of bindings, but I can't see how to do this? I do appreciate any help anyone can offer me, Many Thanks Amy ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
