com.communote.server.web.fe.widgets.extension.ExtendableWidgetFactory

All Implemented Interfaces:

WidgetFactory

public class ExtendableWidgetFactory
extends SimpleWidgetFactory

Factory that uses the WidgetFactoryRegistry to create widgets provided by plugins. The factory uses the registry whenever a widget with a widget group which starts with plugin/ should be created. If a group does not start with this prefix the widget creation is delegated to the parent class. The bundle name of the plugin whose factory should be used can be provided as part of the widget group or as a request parameter named bundleName. In case it is part of the widget group it is expected to follow the plugin/ prefix. If there is no factory for the bundle the widget creation fails.
