I had a property named School defined as a page group; in order to modify the type to simple page I deleted the property (and the related definition class using the refractor) and created a new property with the same name and a different definition class. Problem is that now Pega still sees the property as page group (and the property inside as a page) when I start a case so it can't be proper initialized and rendered!

(Also noticed that if I referesh Pega automaticaly changes the type to page again and works)

How can I work this out?
