Here's a peculiar little case that I hope is easy to resolve. Here's the case I ran into:
I had bound an NSTextField to an attribute of an object. The interface at that point implied that the user could update the value in that field, then immediately click a button to perform an action. The problem was that the value wasn't updated yet, since the user hadn't pressed enter. Just clicking the button apparently isn't enough for the text field to lose focus and commit the changes. To fix, I rewired to use an NSObjectController that pointed at my object, and then bound through that instead of directly to the object. Then, when my save: method was called, I first called [myObjectController commitEditing] and checked its return value. If it succeeded, then there were no validation errors and I continued saving. If it failed, then I bowed out and presented the dialog to the user to fix. Worked like a charm - either my field was saved or the user got an error right away. The problem is that when the button is pressed the error message displays in a new window, whereas if the user were to hit enter, the error message displays in a sheet. I have a simple little test program to illustrate the issue: http://www.bassetsoftware.com/osx/bindingsfail.zip Type in any value to the field. If you type in "Microsoft", it fails with a validation error. If you type it in and hit Return, the error displays in a sheet. If you type it in and hit the "Save changes" button, it displays in a window. It's as if the object controller no longer knows what window it's associated with, so the sheet displays as a window instead. Is there anything I can do differently to get my error to display in a sheet? Because if there isn't something else I can do, I'm going to consider this a bug and file a report.
