Please check the few options listed here Re: Start workflow with a button
If any work as you need, please reply with your best option. Or if you have any questions, let us know.
No Andrew, it doesn't help. My script is failing at the below line
var subscription = wfServiceManager.getWorkflowSubscriptionService().getSubscription(WorkflowInstanceID);
Basically the WorkflowInstanceID looks incorrect. I am using the parameter from the below URL
http://sp2013demo.softura.com/sites/dawnfoods/_layouts/15/NintexWorkflow/WorkflowDesigner.aspx?WorkflowID=6b579313-d717-4f48-b2a1-f4e98e60a2df&Category=List&ListId=4564a564-fbc5-4b66-b9c4-bd0171314f96
Could you use a button that navigates to the url that is similar to
Site URL/_layouts/15/NintexWorkflow/StartWorkflow.aspx?List={List ID}&ID=ID&WorkflowName=MyWorkflow&Source=Item URL.
Kalyan, I think the issue has to do with how you're getting the workflow template ID. In my research for this same topic, I came across a method that we use successfully to start a workflow on multiple selected items in a list. IT uses an SPServices() function. Marc Anderson wrote the script, and in it he uses the workflow name to get the specific GUID. That GUID, along with the current item's URL and any workflow parameters is used to start the workflow. Here's an example of the code, but I suggest you read through his example script for the details.
//Before starting the workflow, we use GetTemplatesForItem to get Workflow Template Id.
$().SPServices({
operation: "GetTemplatesForItem",
item: itemURL,
async: false,
completefunc: function (xData,Status) {
var currentItemURL = this.item;
$(xData.responseXML).find("WorkflowTemplates > WorkflowTemplate").each(function (i,e) {
// SET THE WORKFLOW NAME HERE!
if ($(this).attr("Name") == "Create RecordLabel") {
var guid = $(this).find("WorkflowTemplateIdSet").attr("TemplateId");
if (guid != null) {
workflowGUID = "{" + guid + "}";
$().SPServices({
operation: "StartWorkflow",
item: currentItemURL,
templateId: workflowGUID,
workflowParameters: workflowParams,
async: true,
completefunc: function () {
if (total == counter) {
if (waitDialog != null) {
waitDialog.close();
}
SP.UI.Notify.addNotification("Started workflow process for selected item.",false);
window.location.reload();
}
counter++;
}
});
}
}
});
}
});
Hope this gets you further along.

Hello Gerard,
I am glad that you are looking at my issue.
When I try to run the code the fetch the Workflow ID, I am getting the below error.
Code I tried to execute,
<script src="SiteAssets/Scripts/jquery-1.11.3.js"></script>
<script src="SiteAssets/Scripts/jquery.SPServices-2014.02.min.js"></script>
<script type="text/ecmascript">
var collListItem;
var clientContext;
ExecuteOrDelayUntilScriptLoaded(GetWorkflowID(), 'jquery.SPServices-2014.02.min.js');
function GetWorkflowID()
{
WorkflowInstanceID = "xxxxxx-xxxx-xxxx-xxxx-xxxxxxxx";
var workflowGUID = null;
$().SPServices({
operation: "GetTemplatesForItem",
item: "/Lists/SampleList/DispForm.aspx?ID=390",
async: true,
completefunc: function (xData, Status) {
alert(Status);
$(xData.responseXML).find("WorkflowTemplates > WorkflowTemplate").each(function(i,e) {
// hard coded workflow name
if ( $(this).attr("Name") == "Workflow Name" ) {
var guid = $(this).find("WorkflowTemplateIdSet").attr("TemplateId");
if ( guid != null )
{
workflowGUID = "{" + guid + "}";
}
}
});
}
});
}
</script>
Error I am getting
POST http://sp2013demo.testdomain.com/sites/testsite/_vti_bin/Workflow.asmx 500 (Internal Server Error)
I able to access the Workflow.asmx without any issue with the same user ID.
Not sure what am I missing.
Kalyan, I think the issue has to do with you're attempting to run the GetWorkflowID function directly and without the clientContext. You make references to "$(this)" - which is referring to the clientContext defined in the calling routine. I think your attempt to leave out the multi-select portion removed too much.
My experience with this is that you really need two discreet functions. The main function called by the custom action. In this function you create the clientContext and use it to query the items. You could modify the query to only select the one whose ID matches what you expect. This way you still have a context on which to run the "executeQueryAsync" - which calls your GetWorkflowID function.
In your workflowID function be sure to set the workflow parameters variable as shown:
var workflowParams = "<root />";
and include it in SPServices function. The function won't operate without it:
$().SPServices({
operation: "StartWorkflow",
item: currentItemURL,
templateId: workflowGUID,
workflowParameters: workflowParams,
Good luck,
Gerard
