Error tracker via Activiti

Here is the issue for the Task Manager implementation which supports

• tasks with statuses such as open, running, hanging, allowed
• simple workflows (i.e. multiple people signing a document http://i.gyazo.com/8247c0981cdf003a29a4783272eb4211.png )

For the second requirement, I am going to use Activiti in development.

However, I don't know how to add support for task statuses in Activiti. The built-in custom task can be closed.

Workarounds:

• To encapsulate statuses into code. But I think it smells.

Any ideas?
