Ok here's an example: ZipArchive isZipArchive: FileLocator temp / 'nonexist.zip'
In 6.1, this brings up the nonexistant file dialog if the file does not exist, otherwise it returns true or false depending on whether the file is a zip archive. In 7.0, you get an error "Instance of FileLocator did not understand #utf8Encoded" independent of whether the file exists, is a zip archive or not :-) Cheers, Hans-Martin -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
