Workflow API, JavaScript, Web Scripts

[snig]

Hi

I am trying to initiate a workflow by Workflow JavaScript API, it is called in a Web Script.

Here is the code snippet… It is pretty much exactly same as the examples provided in various Alfresco Wiki pages…

   var workflow = actions.create("start-workflow");
   workflow.parameters.workflowName = "jbpm$wf:job";
   workflow.parameters["bpm:workflowDescription"] = desc;
   workflow.parameters["bpm:context"] = objectSpace;
   //workflow.parameters["bpm:assignee"] = person;
   var futureDate = new Date();
   futureDate.setDate(futureDate.getDate() + 7);
   workflow.parameters["bpm:workflowDueDate"] = futureDate; 
   workflow.execute(objectSpace);
‍‍‍‍‍‍‍‍‍‍‍

It fails saying "Internal Server Error".

However, I tried to debug it by the JavaScript Debugger. It throws a NullPointerException at line
   workflow.execute(objectSpace);

Not sure what is the issue.

Is there any documentation what exactly workflow.execute does? And what should be the parameter passed into this?

Thanks,
Snig.

objectSpace is not defined anywhere.

For the 'start-workflow' action, the parameter to execute() is the node (e.g. document) you want to route through the workflow.

So, as long as you have a handle onto a document you can pass that.  Within a web script, that may be driven by a url parameter, search etc.
