This is an extended version of a page bean that can access the workplace functions, which are an optional part of the CaptainCasa framework.
Within a workplace (e.g. the demo workplace), dialogs can be started in content areas (so called "workpage containers"). The user can start multiple dialogs and navigate in between.
A page bean that is implemented as WorkpagePageBean can access this workplace management and e.g. get notified when the user closes the corresponding dialog or when the user switches between dialogs.
