Vaadin Grid with Generated Properties and Sorting

I have several columns in a Vaadin Grid that only contain values of items that are in a sortable Container, but they're added as Generated Properties as well due to the fact that there needs to be custom HTML title-tag to go with the value. With Generated Property and HtmlRenderer it works and renders fine, but using them makes all the columns unsortable. With a Table this could be done with a CellStyleGenerator I think, but there are several advantages with the Grid. Is there any workaround to fix this and make the columns sortable again?

Using a HtmlRenderer together with a Converter should work otherwise, but I need the object reference itself and not just the field the Converter has, as the html title-tag needs to contain some meta-information.

I recently stumbled upon the same problem if I understood your question correctly.

For me, to make the generated columns sortable, I needed to override the method getSortProperties() when providing the ValuGenerator<T> to the GeneratedPropertyContainer:

GeneratedPropertyContainer container = new GeneratedPropertyContainer(originalContainer);
container.addGeneratedProperty("property-id", new PropertyValueGenerator<T>() {

  [...]

  @Override
  public SortOrder[] getSortProperties(SortOrder order) {
    return new SortOrder[] {order};
  }
});
