That's right. In my case deferring the GET call will not be a problem since this objects will be used in just a few particular places and the workflow is always something like: # Initiate firmware building node.ctl.firmware() # wait until finished while node.ctl.firmware.progress < 100: time.sleep(1) Thanks for sharing your knowledge guys !! -- Marc -- https://mail.python.org/mailman/listinfo/python-list
