Hi all,I have at least two nodes (I have drawn more, but I can reproduce the bug with 2 nodes)
- Node1 --- Node2 (child of Node1) --- Node3 ----- Node4 ----- Node5 - Some other nodes
When the user deletes Node1, I want to delete all children nodes (2, 3, 4, 5). To do so, I use NodeDeleted(), I ask the DataStorage for all derivative nodes of the deleted node and delete them all. A problem arises when the user highlights all nodes and delete them. Some nodes are deleted more then one time. Of course, there are conditions in mitk and in my own code that check if the node is null, but it still fails about half of the time. Since the NodeRemoved() event is thrown *before* the actual deletion, the null/exists checks are useless.
I'm probably not the first that want to delete all the children of a node. I feel that this should be simple. Is there a feature to do it that I'm not aware of?
