tree.addItemClickListener(new ItemClickListener() {
    @Override
    public void itemClick(ItemClickEvent event) {
        menu.expandItem(event.getItemId());
    }
});

this works to me

This working for me:

@Override
        public void itemClick(ItemClickEvent itemClickEvent) {
            final String column = itemClickEvent.getPropertyId().toString();
            final String item = (String) itemClickEvent.getItemId();
            if (column.equals(something)) {
                Boolean collapsed = functieTree.isCollapsed(item);
                LOGGER.debug("COLLAPSED: " + collapsed);
                tableTree.setCollapsed(item, !collapsed);
            }
        }

For example if you want to expand all nodes in vaadin.ui.Tree:

// --- Expand all nodes
for (Iterator<?> it = tree.rootItemIds().iterator(); it.hasNext();) {
    tree.expandItemsRecursively(it.next());
}
