Bug report: can't save values from within nameless parameters

Problem:

Soap UI Community Edition is not able to save values from within nameless query parameters.

Simulation:

Consider following GET request:

GET http://www.example.com/webservice/getconfig?={"username":"someuser","password":"somepassword"}

I'm aware this request is not written in accordance with reference manual, but in order to work, this request requires only one and nameless POST parameter, which value is some JSON structure. Even though it will work, regardless of saving project SOAP UI will drop all nameless parameters.
