Coldfusion 8 - SerializeJSON not serializing

I been developing a site offline on a WAMP setup and have been serializing beans using the SerializeJSON function like so:

propertyImageBean = CreateObject("component","cfcs.beans.property_image").init();
propertyImageBean.setname("test");
propertyImageBean.setalt("test alt");

<cfoutput>#SerializeJSON(propertyImageBean)#</cfoutput>

This has all been working correctly and the code above produces:

{"name":"test","alt":"asdasd","id":""}

However, when I upload my files to the live site the response is just an empty object:

{}

The local version is running on CF9 and the prod version is on CF8, so this is probably what the issue is.

Any ideas?

Thanks

EDIT:

<cfscript>

    propertyImageBean = CreateObject("component","cfcs.beans.property_image").init();
    propertyImageBean.setid(1);
    propertyImageBean.setname("test");
    propertyImageBean.setalt("asdasd");

</cfscript>
<cfdump var=#propertyImageBean#>
<cfoutput>id: #propertyImageBean.getid()#</cfoutput>
<cfoutput>alt: #propertyImageBean.getalt()#</cfoutput>
<cfoutput>name: #propertyImageBean.getname()#</cfoutput>

Outputs (prod server(:

So it looks like it is a problem with the bean, unless there is a config issue on the server.

CFC:

First, setup CF8 locally. http://www.adobe.com/support/coldfusion/downloads.html#cf8proddl

I guess SerializeJSON(cfc) is something new in CF9 that's not available in CF8. This is not an official, documented feature of SerializeJSON I don't believe.

Implement a getMemento() function that returns the variables in as a struct, then you can SerializeJSON on that struct.

/** a public function in Obj.CFC */
function getMemento()
{
    return {
        x=variables.x,
        y=variables.y
    };
}

// outside of the cfc...
obj = createComponent("component","Obj").init();
objJson = serializeJSON(obj.getMemento());

I'd check to see if it's a problem with serializeJson() or with the CFC's methods. Check to make sure the values are actually getting set: does getName() and getAlt() return what you'd expect?

Is there a chance that in a production environment there is an issue with simultaneous requests unexpectedly re-initing that CFC instance?

Can you make an entirely stand-alone CFM & CFC which are both pared down to the absolute minimum number of "moving parts" to demonstrate this problem, and still replicate it on both dev & prod?
