Fill choices for dropdown, radio and checkox questions from a restfull service

[andrewtelnov]

A new choicesByUrl attribute/object has been added into dropdown, radio and checkox questions.
It has attributes:
url : string - the restfull service web url
path: string - the path the data from returning json. For example, for this service, the path will be: "RestResponse;result".
valueName: string - the name of the value in the json array. If it is empty, the first attribute is used.
valueTitle: string - the name of the title in the json array. If it is empty, the title equals to value.
Here is the example of filling dropdown question with the country list:
{ type:"dropdown", name: "country", choicesByUrl: {url: 'http://services.groupkt.com/country/get/all', path: 'RestResponse;result', valueName: 'name'} }

Could any one comment on this functionality?
I have an idea to add parameters. For example, a user select a department, and then the list of employees in the department, using restful service. It will be an ability to use the {department} parameter, bound to the 'department' question value, in url for getting employee list via a restful service.
I am not sure that I am going into the right direction. Does somebody need it?

Thank you,
Andrew
