> getting OutOfMemoryError while serializing page.
> * I have a page containing a ModalWindow showing  a Page.
> * When closing the modal I get the following exception (see below).
> * Objects.setObjectStreamFactory(new WicketObjectStreamFactory()) seem to fix the problem.
> * (using SimpleSynchronousFilePageStore() instead of DiskPageStore also fixes the problem).
> And also some questions:
> * why do we need WicketObjectStreamFactory?
> * is it ok to use it?
> * why isn't it the default?
