Checked question number 2 on a collegues computer, which only had R2 installed and we have the same problem there, so it seems like a configuration problem or something like that.
How do you render the property? You have to use the EPiServer Property control. Or you have to do some "hacks", please see http://tedgustaf.com/sv/blogg/2009/9/parse-an-episerver-xhtml-property-with-dynamic-content/.
Having problems with rendering dynamic content in pages. What gets rendered is the preview control, which doesn't work in the view context. The built-in PageProperty do render in the same way on a page, ie even that one doesn't work.
So I have two questions:
1. Have I missed out on some configuration setting?
2. I do run EPiServer 7 parallell to this EPiServer 6 R2 installation, could that installation mess up something?
