org.olat.course.run.navigation.NodeClickedRef
Description:
TODO: Felix Jost Class Description for NodeClickedResult
useful usage of this class:
1. handled by subtreelistener? yes? break : continue 2. check if visible -> no? genericNonVisMessage : continue (done internally here: check if accessible -> no? noAccessExplanation of calledCourseNode : continue) 4. get new treemodel, new selectedNodeId, new Controller, and new calledCourseNode to build up the gui Initial Date: 19.01.2005
