Angular2 RC 5. No component factory found for dynamically loaded components

All components about to be loaded “dynamically” need to be declared in the entryComponents section of your module. In other words you should end up with something like:

@NgModule({
    imports: [BrowserModule, HttpModule, FormsModule, ReactiveFormsModule, ...MATERIAL_MODULES],
    declarations: [...APPLICATION_PIPES, ...APPLICATION_COMPONENTS, ...APPLICATION_DIRECTIVES, CygnusComponent,
        // Component declarations
        // TODO: refactor to appropriate modules
        ...
        ComponentDispatcherComponent,
        TextCellComponent,
        ...
    entryComponents: [TextCellComponent]
    bootstrap: [ApplicationComponent],
    providers: [...APPLICATION_PROVIDERS, AppStore]
})
export class ApplicationComponent{

Please note that you need to list the TextCellComponent in both the declarations and entryComponents section.
