I have a tree, with multiple selection. Tree has 3 folders with 10 objects in each folder. Folders and objects within folders are all selected.
I made a onSelect command which made objects in folder selected or unselected when folder have been selected or unselected.

@Command
  public void treeSelect(@ContextParam(ContextType.TRIGGER_EVENT)SelectEvent event) {
    Clients.log("selection count before select " + treeModel.getSelectionCount());
    Treeitem item = (Treeitem)event.getReference();
    DefaultTreeNode<treeobject> treenode = item.getValue();
    TreeObject node = treenode.getData();

    if(node.getType() == 1){ // folder
        if(item.isLoaded()) {
            for (Treeitem child : item.getTreechildren().getItems()) {
                child.setSelected(item.isSelected());
                if (item.isSelected()) {
                    treeModel.addToSelection((DefaultTreeNode<treeobject>)child.getValue());
                } else {
                    treeModel.removeFromSelection((DefaultTreeNode<treeobject>)child.getValue());
                }
                TreeNode<treeobject> childNode = child.getValue();
                childNode.getData().setSelected(item.isSelected());
            }
        }else{
            for(TreeNode<treeobject> child: treenode.getChildren()){
                if(item.isSelected()){
                    treeModel.addToSelection(child);
                }else{
                    treeModel.removeFromSelection(child);

                }
                child.getData().setSelected(item.isSelected());
            }
        }
        node.setSelected(node.isSelected());
    }
    Clients.log("selection count after select " + treeModel.getSelectionCount());
  }

The problem:
When i unselect first folder it shows correct info that 22 elements still in selection (2 folders and 20 objects in folders).
And then when i unselect second folder it shows that only 1 element in selection - only third folder element. Selection of objects in third folder disappeared!
