The current itsm.properties file shipped with RLM and ALM contains "display" transition names.  The documentation implies that Internal Names should be used.

The product should be using Internal Names to avoid issues with localised, translated or modified ITSM/SSM installations and will be so modified in a future version.  Until then, ensure that the itsm.properties file uses display names, as it currently does.  Once this product change has been made, an appropriate note wil be inserted in the documentation.
