docs example (on changing severity on 'Anti Google Hacking - 2' policy does not work from API

[andreireiand]

This is the DOCs example:

` MX Web Service Custom Policy Class

pol = mx.get_web_service_custom_policy("Anti Google Hacking - 2") pol.Severity u'high' pol.Severity = 'medium' pol.ApplyTo [] ws <imperva_sdk 'WebService' Object - 'web service name'> pol.ApplyTo = [ws] pol.ApplyTo [<imperva_sdk 'WebService' Object - 'web service name'>]

Create user defined copy of policy

pol_dict = dict(pol) pol_dict['Name'] = 'user defined - %s' % pol_dict['Name'] mx.create_web_service_custom_policy(**pol_dict) <imperva_sdk 'WebServiceCustomPolicy' Object - 'user defined - Anti Google Hacking - 2'> `

In reality, one gets:

`

pol = mx.get_web_service_custom_policy("Anti Google Hacking - 2")

pol Out[388]: <imperva_sdk 'WebServiceCustomPolicy' Object - 'Anti Google Hacking - 2'>

pol.Severity Out[389]: 'high'

pol.Severity = 'medium' Traceback (most recent call last):
