You defined public renderparam in portlet.xml and not on *-objects.xml If you want to use a page param, you will first need to define a public render param on every portlet.xml (since we could use one portlet.xml for multiple portlets, it is not required to redefine a public render param if the portlets are using the same portlet.xml) and then you will need to mark the public render param as supported for each portlet. Once you have done that, you bind the public render param you wish to use on a page level to an alias in *-objects.xml or via the admin portlet.
