[rascio]

hello,
i'm trying to start a workflow from the javascript service:

        var registrationWorkflowDefinition = workflow.getDefinitionByName("jbpm$" + registrationType);
   
   var parameters = new Object();
   parameters["bpm:workflowDescription"] = getRegistrationLabelForDescription(registrationType) + ' registration for ' + node.name;
   parameters["bpm:assignees"] = [person];
   
   var registrationPackage = packagesFolder.createNode('test', 'bpm:package');
   registrationPackage.addNode(node);
   
   var registrationWorkflowStart = registrationWorkflowDefinition.startWorkflow(parameters, registrationPackage);
‍‍‍‍‍‍‍‍‍‍‍‍

but when the code is execute throw the following exception:

Caused by: org.mozilla.javascript.EvaluatorException: Can't find method org.alfresco.repo.workflow.jscript.JscriptWorkflowDefinition.startWorkflow(object,org.alfresco.repo.jscript.ScriptNode).

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

Hi rascio,

I have checked your code with first parameter the package and as the second parameter the properties and it doesn't work.
Could you please indicate if did you chage any more?

Please, Could you post your code for this web script?

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);
