   parameters["bpm:workflowDescription"] = getRegistrationLabelForDescription(registrationType) + ' registration for ' + node.name;
   parameters["bpm:assignees"] = [person];
   
   var registrationPackage = packagesFolder.createNode('test', 'bpm:package');
   registrationPackage.addNode(node);

I've solved it….
The documentation is wrong. The method startWorkflow take as first parameter the package and as the second parameter the properties.

I usually use this code to start workflow with JavaScript:

var wfdef = workflow.getDefinitionByName("jbpm$processid");
if (wfdef)
{
   var wfparams = new Array();
   wfparams["bpm:workflowDescription"] = "";
   wfparams["bpm:assignee"] = "admin";
   var wfpackage = workflow.createPackage();
   for each (var fnode in folder.children)
      wfpackage.addNode(fnode);
   var wfpath = wfdef.startWorkflow(wfpackage, wfparams);
   var tasks = wfpath.getTasks();
   for each (task in tasks)
      task.endTask(null);
