use the 'renderPageVariables' namespace property

Thank you, Wouter. The page variables are now displayed on the page!

However, the sequence in which they are displayed seems to be arbitrary - the page variables should be displayed in the order in which they are modeled as parameters on the signal event of the transition.

hey Matthias this should have been fixed due to changes in the facades implementation in general, all sets have been implemented using a LinkedHashSet instance, meaning ordering is maintained (Chad changed this recently in order to provide for consistent tests between maven1 and maven2, since maven2 does no longer forks a vm when it runs tests), reopen this issue if there should still be a problem
