Niyaz - Yes, that does look correct.
It would be great if we could do a slightly deeper check as the related fix changes the hash to be from the class HashWithIndifferentAccess.
If you could, from the rails console run the following line:
ServiceTemplateProvisionTask.find(2).options[:dialog].class
I would expect it to return "ActiveSupport::HashWithIndifferentAccess"
Instead of the old class type of "Hash"
This would ensure that a caller could access the data with either symbols or strings.
