Dynamically creating components at runtime

[Mark Stang]

All,
This is a 3.x mechanism for dynamically creating components at runtime.  I am 
posting it for two reasons, one is to provide a mechanism for other developers. 
 The second is so that people can review the implementation and point out any 
"concerns".

@SuppressWarnings("unchecked")
    private <T> T newComponent(String componentName, Class<T> baseClass, 
IRequestCycle cycle)
    {
        ComponentSpecificationResolver resolver = new 
ComponentSpecificationResolver(cycle);
        resolver.resolve(cycle, cycle.getPage().getNamespace(), null, 
componentName, null);
        IComponentSpecification spec = resolver.getSpecification();

        IEngine engine = cycle.getEngine();
        Class c 
=engine.getComponentClassEnhancer().getEnhancedClass(spec,baseClass.getName());

        try
        {
            IComponent result = (IComponent)c.newInstance();
            result.setSpecification(spec);
            result.setPage(cycle.getPage());
            result.setContainer(this);
            return (T)result;
        }
        catch (Exception e)
        {
            // Toss any instantiation exceptions up the stack; there's nothing 
to be done
            throw new RuntimeException(e);
        }
    }

Thoughts?

thanks,

Mark
