[V8i C++] Dumping Tool Data via mdlNamedToolDataNode_getToolData()

I'm traversing the ListModel of tasks from mdlNamedTool_populateTaskListModel(). After I load the tool (mdlNamedToolDataNode_loadByPath(), I call mdlNamedToolDataNode_getToolData(). I'm attempting to return the "keyin" string, but that value (and others I know HAVE values) are NULL. I can retrieve the balloon text and ToolPath, but others like TaskID and MainTaskPath are NULL. How can I return the KeyIn string for a tool?

Thanks,

Bruce
