/**
* enclosing_type Description: <br>
* this controller takes a component in its contructor and wraps a velocity
* container around it with a single link/button (with a userdefined
* displayname) which closes the dialog. <br>
* Important: the method getMainComponent is overridden and throws an Exception,
* since there is a different method to be used: activate(WindowController
* wControl). This reason is the this controller is intended to be used only as
* "a popup"/modal dialog (since it offers the 'close' button) and after
* clicking that button, it should disappear by itself. Therefore you can only
* use it in conjunction with a WindowsController.
