doc/tutorial/deserialize.py is failing about spiffworkflow

I just committed a fix in ee84959

Thanks, but after ee84959 another error occured, when running deserialize.py
@knipknap

Traceback (most recent call last):

This sounds like your workflow spec may be wrong. Does your JSON contain the "name" and "file" fields?

After running the code
open('workflow-spec.json', 'w').write(pretty)
in serialilze.py, the program outputs JSON string into workflow-spec.json, which I used in deserialize.py.
And the JSON string is

"{"description": "", "file": null, "name": "", "task_specs": {"Start": {"class": "SpiffWorkflow.specs.StartTask.StartTask", "data": {}, "defines": {}, "description": "", "id": 1, "inputs": [], "internal": false, "locks": [], "lookahead": 2, "manual": false, "name": "Start", "outputs": ["general"], "post_assign": [], "pre_assign": []}, "general": {"choice": null, "class": "SpiffWorkflow.specs.ExclusiveChoice.ExclusiveChoice", "cond_task_specs": [[["SpiffWorkflow.operators.Equal", [["Attrib", "confirmation"], ["value", "yes"]]], "president"]], "data": {}, "default_task_spec": "workflow_aborted", "defines": {}, "description": "", "id": 2, "inputs": ["Start"], "internal": false, "locks": [], "lookahead": 2, "manual": false, "name": "general", "outputs": ["workflow_aborted", "president"], "post_assign": [], "pre_assign": []}, "nuclear_strike": {"class": "SpiffWorkflow.specs.Simple.Simple", "data": {}, "defines": {}, "description": "", "id": 5, "inputs": ["president"], "internal": false, "locks": [], "lookahead": 2, "manual": false, "name": "nuclear_strike", "outputs": [], "post_assign": [], "pre_assign": []}, "president": {"choice": null, "class": "SpiffWorkflow.specs.ExclusiveChoice.ExclusiveChoice", "cond_task_specs": [[["SpiffWorkflow.operators.Equal", [["Attrib", "confirmation"], ["value", "yes"]]], "nuclear_strike"]], "data": {}, "default_task_spec": "workflow_aborted", "defines": {}, "description": "", "id": 4, "inputs": ["general"], "internal": false, "locks": [], "lookahead": 2, "manual": false, "name": "president", "outputs": ["workflow_aborted", "nuclear_strike"], "post_assign": [], "pre_assign": []}, "workflow_aborted": {"cancel_successfully": false, "class": "SpiffWorkflow.specs.Cancel.Cancel", "data": {}, "defines": {}, "description": "", "id": 3, "inputs": ["general", "president"], "internal": false, "locks": [], "lookahead": 2, "manual": false, "name": "workflow_aborted", "outputs": [], "post_assign": [], "pre_assign": []}}}"

Ah, the error was in serialize.py. Fix is committed.

Problem solved, Thanks.
