Create a composite object by using the CreateChild method.
Example
The composite object contains both a list object (defined in qListObjectDef) and a chart (defined in qHyperCubeDef).
The list object has one dimension Country (qFieldDefs is Country).
The chart has one dimension City (qFieldDefs is City) and one measure Count(Holes) (qDef is "Count(Holes)").
The client sends:

},
"qInfo": {

},
"change": [

]
}
The composite object is created. The handle is 3.
