I can’t (yet) reproduce it and therefore this post is going to be very vague but important enough.
I was demoing my application to my customer yesterday and did several screen navigations. Almost all screens receive a controller.readOnly = true/false based on their stage and I think the issue lies herein.
After something like 2 hours the application (which I demo’d on OS X developer v2.0rc2) freezed. I could not wake it up anymore.
That’s it. I can’t tell if this was the developer or the application. Can’t tell what caused it etc. The only thing I know that the form freezed without giving me any access to any control afterwards. A shutdown of developer (from the finder) was the only possibility left…
