To load the externally stored data in self context, you need to call the <<PersistentStateAdapter>> with action loadExternals.
If you have loaded the external data once in a persistent state transaction, it will be considered loaded by the xUML Runtime. Subsequent calls of loadExternals will be omitted and logged to the service log (log level DEBUG). This is to prevent modelers to accidentally overwrite changes to the persistent state object.
