Link: Added: This issue depends MODE-1083

I've found the problem. ModeShape's NodeTypeManager implementation caches maps of the property and child node definitions (keyed by their internal identifier), and this map was not being updated when the manager was being notified of changes to the node types (from other members of the cluster). The simple fix is to update these cached maps in the same logic where the manager is already processing the notifications.

This error will prove to be a problem in all clustered configurations, and thus is a fairly significant issue. Luckily, the change is quite minor and isolated to the RepositoryNodeTypeManager class, and only occurs when the engine is in a clustered environment. See MODE-1083 for details.

For the record, as part of MODE-1083, I've created a pull-request to describe the proposed changes to the code: https://github.com/ModeShape/modeshape/pull/10

I'm currently waiting for approval to merge to the '2.2.x' branch before I do so on the 'master' branch. 

(If you're not familiar with GitHub, click on the "Files Changed" tab to see the proposed changes. Feel free to comment on the pull-request. 

After approval by Van, I've merged the proposed changes from MODE-1083 onto the 'master' and '2.2.x' branches, and marked MODE-183 as resolved.

Verified on ER8.
