To Enable Wiki Portlet to Display Channels and/or Portlets

The wiki portlet must be the first selected element of a DynamicAggregationContainer. The display profile of the Developer Sample desktop and of the sample wiki community include such a container. The wiki portlet can display and aggregate any channel or portlet that is in the available list of the DynamicAggregationContainer. If a channel is not in the available list, it will not appear on the page with no error or other indication. This allows the wiki portlet to include different channels for different users based on their display profiles.
