I have a page with a property of type ContentArea. I have various blocks making up content of this page in the ContentArea. The ContentArea is being rendered on the page using <EPiServer:Property ... /> tag.

I need to be able to allow certain users the ability to view unpublished changes to a block on a page. I'm going to use VirtualRoles based on querystring (as suggested by Johan here: http://world.episerver.com/Modules/Forum/Pages/Thread.aspx?id=82244&epslanguage=en)

But the preview link doesn't show the un-published versions of blocks in the ContentArea.

How can I make EPiServer use draft versions of blocks in this preview view?
