Unable to execute script, returns null.

and my javascript to call the workflow

var workflow = actions.create("start-workflow");
workflow.parameters.workflowName = "jbpm$wf:pengesahan";
workflow.parameters["bpm:workflowDescription"] = "Proses pengesahan dokumen : "+document.properties.name;
workflow.parameters["bpm:groupAssignee"] = "GROUP_KETUA URUSETIA SEKRETARIAT";
workflow.parameters["bpm:approveDestination"] = "Sites/ar-rahnutest/documentLibrary/PAPARAN";
workflow.parameters["bpm:rejectDestination"] = "Sites/ar-rahnutest/documentLibrary/TIDAK DILULUSKAN";
var futureDate = new Date();
   futureDate.setDate(futureDate.getDate() + 3);
   workflow.parameters["bpm:workflowDueDate"] = futureDate;
workflow.parameters["bpm:workflowPriority"]="2";
workflow.parameters["bpm:mailSubject"]="Peringatan : Sila lakukan pengesahan";
workflow.execute(document);

Actually this is my second custom workflow. The first one works fine. The only difference is the wf:name and the xml filenames.
This new custom workflow would return unable to execute script because of null (after checking with logs, this I believe happens at line workflow.execute()).

Maybe I've missed something?

Thanks in advance.

Have you ever checked whether your process definition is successfully deployed using workflow console?

[e-no91]

Hi, Thank you for the reply.

I've just checked and found out that instead of running the workflow, it runs the previous workflow that I used, wf:reviewpooled.
But I set the name as wfengesahan, to run that workflow, what mistake have I done here?

[kaynezhang]

1.Excecute "show definitions" command in workflow console ,make sure your definition is successfully deployed and make sure you specify the correct definition name in your javascrpt code.
2.I guess maybe you made somewhere,you can write your javascript code like below and it will give you more log info.

var wfdef = workflow.getDefinitionByName("jbpm$wf:pengesahan");
logger.getSystem().out(wfdef.getName());

var wfparams = new Object();
wfparams["bpm:workflowDescription"] = "Proses pengesahan dokumen : "+document.properties.name;
wfparams["bpm:groupAssignee"] = "GROUP_KETUA URUSETIA SEKRETARIAT";
wfparams["bpm:approveDestination"] = "Sites/ar-rahnutest/documentLibrary/PAPARAN";
wfparams["bpm:rejectDestination"] = "Sites/ar-rahnutest/documentLibrary/TIDAK DILULUSKAN";
var futureDate = new Date();
futureDate.setDate(futureDate.getDate() + 3);
wfparams["bpm:workflowDueDate"] = futureDate;
wfparams["bpm:workflowPriority"]="2";
wfparams["bpm:mailSubject"]="Peringatan : Sila lakukan pengesahan";
var wfpackage = workflow.createPackage();
wfpackage.addNode(document);
wfdef.startWorkflow(wfpackage,wfparams);

Hi,
Thank you! I'll try this out later.
I have to test out other things so I have to stick to using and editing from the workflow folder..

[muralidharand]

Hi,
When you re-deploy your worklow in alfresco, it creates new version of the workflow.
So, please use the workflow console and find out how many versions of workflow you have.

Thanks.

Hi,
Does this means that it is better to leave the redeploy parameter as false?
So everytime I make changes to the workflow, does it still take effect?

Thank you.
