__LamelPageArray &LamelPageFactory()

	if(!pages)
		pages = new __LamelPageArray;

	return *pages;
}

Why not

__LamelPageArray &LamelPageFactory()
{
	static __LamelPageArray pages;
        return pages;
}

Yep, better... and it could be made a static member of Page class, also.

Also, I believe that

void CreateClassInstance(One<BaseClass>& x);

(Note that you can do x.Create<DerivedClass>())

or even in some cases

void CreateClassInstance(Array<BaseClass>& x);

is cleaner class factory interface. (But depends on your taste).

mhhh... I don't understand your point. I need the class creation at runtime by name, so an ascii string, not a type.
Anyways, thinking about it, all the stuff could be polished a bit, also using callbacks, maybe, instead of function pointers.

BTW, yesterday I was in a hurry because the problem was starting boring me, so I solved it quick and dirty Smile
