startWorkflow(workflowPackage, properties?)

[jamesc5]

Hi,

I've got 2.9B installed on windows server 2003. I'm trying to figure out the Workflow Javascript API. The wiki (http://wiki.alfresco.com/wiki/Workflow_JavaScript_API) says JscriptWorkflowDefinition has a method

startWorkflow(workflowPackage, properties)
‍‍‍

What is properties, the second argument? Also, what does this method return? I'm assuming it's a workflowInstance. This is what I've got so far. Which doesn't work (throws a null pointer exception).

var pack = workflow.createPackage();
var workflowInstance = workflow.latestDefinitions[1].startWorkflow(pack, null);

After banging around a bit I've found this post:

In the java code I see that params is

Map<QName, Serializable>
‍‍‍

Question: Is there a way to access the QName constants from WorkflowModel in javascript? If not, what is the correct way to construct the params to start a workflow from javascript?
