Django ViewFlow: Navigate Step based on Validation

I am using the HelloWorld example located at the ViewFlow cookbook.
The whole source code is same as the helloworld project with the only change being:

flows.py

check_approve = (

    flow.If(lambda activation: activation.process.approved)

    .Then(this.send)

    .Else(this.start)  # Edited (was this.end)

)

So basically I intend that if user keeps the Approved checkbox as un-selected and proceeds then it will push the task back to the start step.

I get this error when I run it:

NotImplementedError at /workflow/helloworld/helloworld/3/approve/11/

No exception message supplied
