Cloudify rest plugin - not possible to save rest call responses in particular scenario

[mareklabonarski]

Having a custom workflow defined, which triggers a rest call operation, it's not possible to store responses from other rest calls than the first one (from first workflow execution).

There is no trace of next calls at all in runtime properties. Please see the code and runtime properties after triggering the workflow three times with values 1, 2, 3 respectively:
