Returning an instance of a page

Hi all.

Quick newbie question: How do I return an instance of a page whose class I do not know until at runtime? Example: I have a list page, listing objects of various types. when I click an object, I want to return a page class based on the class of the object I select ("UserDetailPage" for "User", "CompanyDetailPage" for "Company" etc…).

@InjectPage requires me to specify a particular page at compile time, so I can't use that—and I cant do a plain "return UserDetailPage.class" since I need to set the selected object.

Any ideas?

Thanks,
- hugi

Yes, that would work for returning the page, but I need to initialize it (with the object). In pseudocode, what I'm looking for wouls be something along the lines of:

	Object onActionFromSelect() {
		Class<? extends DetailPage> detailPageClass = determineDetailPageClass( currentObject );
		DetailPage detailPagePage = // obtain page instance of type detailPageClass
		detailPage.setSelectedObject( currentObject );
		return detailPage;
	}

(the detail pages all inherit from DetailPage)

Cheers,
