How do you start a Workflow on a bundle in using the Event System?

Question

How do you start a workflow on a bundle in the Event System in Tridion 2013 SP1?

Which DLL's do I need to refer to do so?

I have created a bundle ("tcm:26-135-8192") in Tridion and I have associated a Bundle Schema with it which has a workflow.

Bundle bundle = (Bundle)item.Session.GetObject("tcm:26-135-8192");
bundle.AddItem(item); 
bundle.Save();

StartWorkflowInstruction instruction = new StartWorkflowInstruction(item.Session);  

instruction.Subjects.Add(bundle);  

ProcessInstance result = bundle.ContextRepository.StartWorkflow(instruction);

My requirement is to add items to this bundle through event system and start the workflow on this. But i am getting a Error on bundle.Save(); which says "Item is shared".

Any suggestions?

This is what I am getting in Event Viewer . I have created this Bundle in publication 18 and I am trying to add one item in publication 26. Should i be creating this bundle in piublication 18 as well.

The item is shared.

Answer 1

Use the TOM.NET API to make certain Workflow-related events in Content Manager trigger a piece of custom code you write. You can subscribe to a number of moments before, during and after a specific event.

Events related to Workflow are in the Tridion.ContentManager.Extensibility.Events namespace.

It is not possible to add/remove items to/from a bundle in shared/localized context. Ideally you should create the bundle at the lowest level in your blueprint where all of the items you want to add are available. Shared/localized items can be added to bundle. Then start workflow on that bundle.

StartWorkflowInstruction instruction = new StartWorkflowInstruction(session);
instruction.ProcessDefinition = myProcessDefinition; // Optional, otherwise it is going to use the configured task process of the bundle.ContextRepository
instruction.Subjects.Add(bundle);
ProcessInstance result = bundle.ContextRepository.StartWorkflow(instruction);
