Getting Workitem in a service

I recently implemented a service that I am injecting in the ModuleController. I created an AddServices() and call it from the Run() in the ModuleController. I have a member in my service called _workItem that is of type WorkItem, and a get method:

public WorkItem WorkItem {get return _workItem;}

In my service I am accessing the WorkItem, but the program crashes, and when I debug the line of code trying to access the WorkItem, it says that it is null.

I was just wondering, am I properly injecting the workitem in the service for use, or am I doing something wrong? Any help would be much appreciated.

public WorkItem WorkItem {
  get { return _workItem; }
  set { _workItem = value; }

Hi Matias,
   I used this solution, but I have got problem that it didn't set right WorkItem. How can I assure that specific business WorkItem will be set? Does it depend on place where the service is injected? I set my service in presenter class, as this:

      private IToolbarProviderService _toolbarProviderService;
      public IToolbarProviderService ToolbarProviderService
         set { _toolbarProviderService = value; }

     Thanks for any tip. X.

The WorkItem that gets injected is the WorkItem in which you created and/or added the service. So, to assure that specific business WorkItem will be set, you should add the item to that specific business WorkItem.

Another possibility would be a Dependency on the WorkItem's name:

public WorkItem BusinessWorkItem{get;set;}

therefore you have to explicitly set the ID of the WorkItem after it was added to a WorkItemsCollection above the hierarchy:

WorkItem BusinessWorkItem = RootWorkItem.WorkItems.AddNew<WorkItem>();
BusinessWorkItem.ID =
