Re: [json-lib-user] Convert collection of beans to json

Vadim,

You can't transform a Collection into a JSONObject.  Collections and arrays can only be transformed into JSONArray

Subject: [json-lib-user] Convert collection of beans to json


Hello, 

I've been trying to solve this for couple of hours now. I need to transform 
Collection<Vehicle> to JSONObject, where 
Vehicle (id = 1, regNr = 2) -> JSONObject.toString() == "{'id':'1', 'regNr':'2'}"
{Vehicle (id = 1, regNr = 2), Vehicle (id = 2, regNr = 6)} -> JSONObject.toString() == "{'id':'1,2', 'regNr':'2,6'}" (not "{'id':'1', 'regNr':'2'}, {'id':'2', 'regNr':'6'}")

JSONSerializer.fromObject(Collection) returns an array of separate objects transformed to JSON ("{'id':'1', 'regNr':'2'}, {'id':'2', 'regNr':'6'}"). 
Of course I could do the needed transformation by hand, but I'm sure there's something in the API that I'm missing.
