| I checked what is AbstractTreeDataModel.setWrappedData responsilble for:
|
|
| | public final void setWrappedData(Object data) {
| | wrappedData = (TreeNode) data;
| | }
| |
|
| so, I have put a breakpoint there and checked what Object data appear to be. As expected it was my implementation of TreeNode.
