AWS SWF - IllegalStateException: No context found. (method called outside the workflow definition)

I am writing an AWS SWF application using the flow framework. Getting an IllegalStateException: No context Found. It means that the method is called outside of the workflow definition code. while calling the following code:

private DecisionContextProvider contextProvider
     = new DecisionContextProviderImpl();

private WorkflowClock clock
     = contextProvider.getDecisionContext().getWorkflowClock();

Why am I getting this error and how to get rid of it?

This exception is thrown by getDecisionContext() when you call it outside of a workflow (it should only be called somewhere in the call hierarchy of your workflow implementation - ie, your WorkflowImpl ).

To avoid getting that error, you should only call getDecisionContext() while inside of a workflow or its constructor. The object only gets set in those circumstances (by the simple workflow framework), and doesn't exist outside of workflow execution, hence the IllegalStateException.
