I haven't used confirmation dialogs in GWT before--I've only used them
in straight Javascript--so take the following with a grain of salt.

You're greatly confusing matters. Just use Window.confirm():
public boolean doBeforeMoveNode(Tree tree, TreeNode node, TreeNode
oldParent, TreeNode newParent, int index) {
GWT.log("treePanel.onMoveNode", null);
if (oldParent.getId().equals(newParent.getId())) {
return false;
}
return Window.confirm("You are about to move this node and its child
nodes. Press OK to save your changes to the database, or Cancel to
lose your changes.");
}
See the Window.confirm() doc here:
