I am trying to change the structure of my reordering tree based on a selection event from another table. I tried a lot of things and nothing seemed to work. My final approach is as follows: I keep a reference to reordering tree's treestore and its root item's model. They are respectively named as store and dragRoot.
Here's the code that I use to add a node to the tree. When it's executed, it creates two nodes under the root of the tree. I can't seem to understand what is wrong with this.
MediasetModel md = new MediasetModel("am",1);
store.add(dragRoot, md, false);
Can somebody please help me, I struggled about this problem at least for 2 days, and it looks like it's one of the most basic functionality of a tree, It isn't supposed to be this hard. Nobody seems to be able to help.
