Hi, I use application scoped secure bookmarks to automatically reopen documents in one of my iTunes Store MacRuby applications. Recently the NSURL constants NSURLBookmarkCreationWithSecurityScope and NSURLBookmarkResolutionWithSecurityScope became undefined. I updates both to BridgeSupport Preview 3 and to 10.8.3 developer beta since I last ran the program so I don't know which update caused the problem. def bookmark_for_document( document ) error = Pointer.new( :object ) bookmark = document.fileURL.bookmarkDataWithOptions( NSURLBookmarkCreationWithSecurityScope, includingResourceValuesForKeys:nil, relativeToURL:nil, error:error ) unless bookmark ErrorLog.instance.error( "error creating bookmark #{ error.value.inspect }" ) end bookmark end 2013-03-06 20:53:41.823 MacDriverLog[2302:303] An uncaught exception was raised 2013-03-06 20:53:41.824 MacDriverLog[2302:303] /Users/robertrice/Library/Developer/Xcode/DerivedData/MacDriverLog-ebberjlfoqoqdzenjgqkdbkehuoj/Build/Products/Debug/MacDriverLog.app/Contents/Resources/DocumentsSheetController.rb:187:in `bookmark_for_document': uninitialized constant DocumentClassTableObject::NSURLBookmarkCreationWithSecurityScope (NameError) from /Users/robertrice/Library/Developer/Xcode/DerivedData/MacDriverLog-ebberjlfoqoqdzenjgqkdbkehuoj/Build/Products/Debug/MacDriverLog.app/Contents/Resources/DocumentsSheetController.rb:174:in `add_document' from /Users/robertrice/Library/Developer/Xcode/DerivedData/MacDriverLog-ebberjlfoqoqdzenjgqkdbkehuoj/Build/Products/Debug/ Thanks, Bob Rice
