Leave it out, set it to upgrade and set it to update. Is there a bug or can someone please enlighten me? -- Ali _______________________________________________ Do not post admin requests to the list.

This email sent to site_archiver@lists.apple.com There's three different scenarious of the use of BundleOverwriteAction in the component.plist-file. The latter two cases are explained in the man-page. I tried them with a single flat-package but they do the same no matter which case I try. Files appearing in both packages are replaced while other files which were only in the first package but not the second aren't deleted on the disc. This was even the case when using the upgrade value in the component.plist. Here's what I did to try that. I made two flat-packages. One with a lot of different files and folders (version 1.3.0) and another one with just the .app-file (version 1.3.1). I installed version 1.3.0, then 1.3.1. What I wanted to achieve was having everything deleted but the updated .app-file after installing version 1.3.1. Still all other data was still there as mentioned.
