IMHO the big selling point of OSGi, is the ability to add additional packages as you go. If the package is needing an api of a particular version that isn't in your environment it just won't turn on.
If the bundle is defined correctly, which I admit, seems to be a difficult thing to do. Then the version of the bundle is less important then the package version of the api's that it exports. -Jason -----Original Message----- From: Roy Teeuwen [mailto:r...@teeuwen.be] Sent: Saturday, August 20, 2016 8:28 AM To: users@sling.apache.org Subject: Re: Sling models adaptTo taglib Hey Dan, Ok cool, thanks, I guess it is indeed just a patch version upgrade from 2.2.4 to 2.2.6, so it’s worth a shot :)!
