As far as I can see, an advantage with attaching static stuff to OFS.misc_.MyInstalledProduct is that it becomes available globally which makes sense to avoid loading a different icon URL for each www icon in the ZMI of a product. Makes sense also for example if you have one Zope with 10 different instances because then there's just one on /misc_/MyProduct/screen.css to cache and download for the browser if you've placed a static file there called that. A drawback seems to be that errors happening in /misc_/MyProduct/static-content isn't reported in the error_log. This makes it hard to spot bugs in objects in there and, more commonly, NotFound errors. Is there anything I can do about that or should I not expect so much and instead use the instance? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com
