Description

often it is useful to have feedback panels that only display messages coming from a certain container. there are two problems with using a simple ContainerFeedbackFilter:

• it does not support nesting. if two panels using the filter are nested and an inner component reports a message it will be shown in both inner and outer feedback panels - duplicating the message
• there is no easy way to have a top level panel that only shows messages that will not be shown in any other panel
