I have a JTree and a button in the UI called up. When i select a node and say up, it is supposed to move that node up. The problem is that the first time it works fine but the second time that node disappears completely from the tree.
You started this topic about a month ago, and as I recall you got the solution for your "moving node up" problem (though the point was to select the node moved up, but still the code was working fine for what you want).
The quieter you are, the more you are able to hear.
