gov.nasa.arc.mct.services.component.ComponentRegistry.newInstance()
Create a new instance of the specified component class. Components must be initialized with the MCT framework, so this method must be used when creating instances of components. Failure to do this will result in components which are not fully initialized and the system behavior when using these components is undefined. @param < T> specific base component type to create @param componentClass used to identify a component. @param parent to add newly created instance to. This value can be null which signifies that this will only show up under the created by me area. @return a new component instance or null if there is no component matching the given componentClass

    // will be injected through the OSGi declarative services model
    ComponentRegistry registry = ComponentRegistryAccess.getComponentRegistry();
    
    if (registry != null) {
      // use the ComponentRegistry service to create a new instance of a component
      ExampleComponent ec = registry.newInstance(ExampleComponent.class, component);
    
      // additional information can be collected here to populate a model. This simply
      // sets a unique name 
      ec.setDisplayName("newComponentFromMenu"+newCount.incrementAndGet());
