Svatopluk Dedic updated NETBEANS-3252: -------------------------------------- Description: I have an implementation of ListView with checkboxes for individual displayed Nodes. The *NodeListModel* maintains a cache of nodes, so it can compute node vertical index considering nodes in individual subtrees. When firing *contentsChanged* event, the cache is not cleared *before* the event; so if an event listener attempts to access the visualizer cache (i.e. *getIndex()*), it gets an incorrect data. A workaround is to schedule the action to another Swing event, but I'd rather fix the bug. was: I have an implementation of ListView with checkboxes for individual displayed Nodes.
