I tested it on my hudson server you can rename a job without breaking any dependencies to other jobs. I tested upstream trigger, copy artifacts. I don't know other dependencies. Norbert

I'm too. The changes we are proposing to not break the default use of the system. ***All the queries that a normal user will do will share the same default environment *** and only when we will need to browse/query another systemDictionary we will have to make sure that the environment points to the right systemDictionary and that the queries access this root (which they do). Show me how this is wrong. We need it. So if you do not want to help I cannot do too much and I will fork because all our efforts to make the system parameterized will not be blocked just because you do not want to take 5 min to listen carefully what we are saying.

You would be provided with the possible things to commit, and then you would not have to think about the mapping at all. All you have to do is select each of the RPackages that you want to commit, and if there does not exist a correspondent Monticello package for it, you would be asked to provide the repo and then the creation would happen transparently. > >> So we could always load and create a RPackage for each Category.
