Hi all, If you adopt the new +autosavesInPlace feature on Lion, documents that haven't been opened in a while will get a "Locked" message in the titlebar, which the user can override by clicking and choosing "Unlock," or by attempting to make a change to the document and choosing "Unlock" from the resulting sheet.
I'm trying to force a document to open as locked. The use case is for upgrading documents from our previous file format. In the past, if the user tried to open an old file, we'd upgrade the document, place the new version alongside the old version, and open the new version. We can't do that in the new sandboxing world. So we thought we would open the old version Locked, and if the user tried to make a change we'd present a sheet saying the document was locked because it was in an older file format; the sheet would contain a "Duplicate and Upgrade" button. Unfortunately, it doesn't look like there's any public API to force a document to be locked. The closest I've come is -[NSDocument checkAutosavingSafetyAndReturnError:], but it doesn't seem to be called at all the times I'd expect it to be called (for example, a new document), and returning NO doesn't put the Locked text in the titlebar; it just prohibits the user from making any changes without duplicating. Likewise, returning YES from -isInViewingMode just makes it impossible to make any changes to the document. We already support the notion of "read-only documents" in this application, and it would be a shame to reimplement something similar to NSDocument's concept of locked documents, especially if the two fight with each other. Is there any way to hook into the "locked documents" machinery?
