. Checkpoint for the Rhino JavaScript engine integration:
- Additions to the Alfresco JavaScript data-model . JUnit test for each entry point into Rhino and the ScriptService - tests for various API calls on the Scriptable Node object . More javadoc clean-up in templating and script services git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@2726 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
