a) What parameter is becoming null? (I assume "message", since it's the only parameter defined in CFolderList.jwc, but...?) b) it's looks as though you're defining the component's in the spec, but doing all the binding in the template? Could you attach the html template for the page file, as well?
Is it the "message" parameter which goes to null? That's the only parameter I see in the only .jwc file you attached between the two e-mail messages you sent. Maybe you're doing your binding in the .html file??? Because I'm not seeing anyplace in the .page file where you bind the CFolderList's message parameter to any of the page's properties...
