Examples of org.apache.wicket.AccessStackPageMap

org.apache.wicket.AccessStackPageMap
A container for pages held in the session. IPageMap is a parameter to several methods in the Wicket API. You can get a IPageMap by name from a Session with Session.getPageMap(String pageMapName) or more conveniently with PageMap.forName(String pageMapName). But you should not hold onto a reference to the pagemap (just as you should not hold onto a reference to your Session but should get it each time you need it instead). Instead, create a strongly typed accessor method like this:
```
 public IPageMap getMyPageMap() { return IPageMap.forName("myPageMapName"); } 
```
If the page map with the given name is not found, one will be automatically created. @author Jonathan Locke
