User: Stephan Bösebeck Date: 27.05.12 Time: 14:14

Connects to the Messaging system and to morphium. As soon as there is a message coming with name "cacheSync", this is responsible for clearing the local cache for this entity. Messaging used:

• Msg.name == Always cacheSync
• Msg.type == Always multi - more than one node may listen to those messages
• Msg.msg == The messag is the Reason for clearing (remove, store, user interaction...)
• Msg.value == String, name of the class whose cache should be cleared
• Msg.additional == always null
• Msg.ttl == 30 sec - shoule be enought time for the message to be processed by all nodes
