This is indicative of a poor design, sorry to say. You haven't separated the concerns in one part of your app from another. It's not necessarily pertinent to your crash, but bad design often covers up those sorts of issues, making debugging hard and difficult to spot when you read through the code. A sheet should have its own controller and this controller should have sole and limited responsibility for the controls and elements within the sheet ONLY. It is up to you to design the methods that the sheet presents to its clients (e.g. the document that brings the sheet up) and any protocols necessary such that this principle is maintained. That way you have separated the internal design of the sheet from the internal design of its client, and neither needs to know about the other, except where they communicate through their public interface which constitutes the sole contract between them. Basically, if your sheet is touching text fields that belong to another object, you've cut corners too far and need to revise that. I bet if/when you do the crashing bug will reveal itself as obvious. --Graham _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
