Now I’m sure there’s a reason for this but it makes me sad a bit. Especially when working with a team of developers. Recently I found myself in the following situation,
My team and I had been building a Force.com application and were interested in implementing an UAC model. We had setup the UAC model on one of the Orgs using profiles, roles and sharing rules(we had some issues here too) and then attempted to commit these changes into our SVN repository. Happy that things were going so well, each developer checked out the code and BHAM! we were no longer able to deploy object definitions. [Slow pan to me on my knees screaming to the heavens. A thunderbolt, then a thunderclap overhead]
