var context = SP.ClientContext.get_current(); var web = context.get_web(); var wfServiceManager = SP.WorkflowServices.WorkflowServicesManager.newObject(context, web); var subscription = wfServiceManager.getWorkflowSubscriptionService().getSubscription(_workflowId); context.load(subscription); ... and then on with the async query
The problem is with the
wfServiceManger.getWorkflowSubscriptionService() part. Sometimes the wfServiceManager is created with a context object in it and other times it isn't. I get the following error when there is no contextobject in the workflowServicesManager:
Uncaught TypeError: this.get_context is not a function at SP.WorkflowServices.WorkflowServicesManager.getWorkflowSubscriptionService
I can't see any reason why one time it would return a properly formmed WorkflowServicesManager and other times not.
I'm finding some other places where people get the
this.get_context() is not a function. Those seem to revolve around loading of required js files. I'm loading:
And they all seem to be loaded and available (as best I can tell from the debugger).
