Rudder

(the title may be wrong or misleading)

For the PT rpmPackageInstallation, there are 3 version on the filesystem and on the git:
1.0
2.0
2.1

The ldap tree contains only version 1.0 and 2.0, and a PI is based on PT 2.0
When showing the PI, I have the following error
16:11:53.351 [qtp746169063-71] ERROR net.liftweb.http.LiftRules - Exception being returned to browser when processing Req(List(F54839448872HJKK1Y), Map(F54839448872HJKK1Y -> List
