ColdBox Bean to JSON

handler.cfc

// all tasks to be returned
var arrTasks = [];

// single task bean to be populated
var oTask = wirebox.getInstance("Task");

// example of a set method
oTask.setCode( "whatever" );

// add bean to array
arrayAppend( arrTasks, oTask );

//return as JSON
event.renderData( type="JSON", data=arrTasks );

/*
JSON result:
[{"CONSTRAINTS":{},"$MIXED":true,"Code":"whatever"}]

*/

Task.cfc

// transient bean
component accessors="true" {

	// properties
	property name="Code" type="string";

	// validation
	this.constraints = {
	};

	function init(){
		return this;
	}

}

A simplistic way to show that CONSTRAINTS and $MIXED get added to the JSON response of a bean.
