private boolean openNode(TreeNode node, TreePlace place) {
  int childCount = node.getChildCount();
  for (int i = 0; i < childCount; i++) {
    if (node.getChildValue(i).equals(place)) {
      //node.setChildOpen(i, true, true);
      return true;
    } else if (!node.isChildLeaf(i)) {
      boolean wasOpen = node.isChildOpen(i);
      TreeNode child = node.setChildOpen(i, true);
      if (child != null && openNode(child, place)) {
        return true;
      } else if (!wasOpen) {
        node.setChildOpen(i, false);
