Coldfusion extended component missing parameters

Question

I'm trying to get a CFC (webCFC) with a remote function to return an instance of a different CFC (objCFC).

Here are the CFCs:

#webCFC
component { 
    remote function displayCFC(version=1) {
        if(version==1) {
            return new baseCFC();
        } else {
            return new objCFC();
        }
     }
 }

#baseCFC
component 
    accessors="true"
    persistent="true"
{
    property name="name" default="pete";    
}

#objCFC
component 
    extends="baseCFC"
    persistent="true"
    accessors="true"
{
    property name="age" default="30";
}

If I call this URL: /webCFC.cfc?method=displayCFC&returnFormat=json, I get this response:

{
"name" : "pete"
}

which is fine. If I call this URL: /webCFC.cfc?method=displayCFC&returnFormat=json&version=2, then the response is missing the property from baseCFC

{
"age" : 30
}

I would expect the response to look like this:

{
"name" : "pete",
"age" : 30
}

I know that I can use the setName() and getName() functions on objCFC, it is definatly extending baseCFC but the extended properties don't show if I access the CFC through the browser.

Is it possible to get this to work?

This could be related to the seralizejson bug (not sure when will it ever be bug free).

A workaround would be to implement your own getMemento() or toJSON() method that returns all the desired properties in a struct. Then serializeJSON that struct instead.
