Vaadin 14 Grid Component Column containing checkbox does not sort

I am using Vaadin 14 grid. This grid contains a number of columns. A few of them need to represent boolean values, hence we use a checkbox component inside that column. This is done by using grid.addComponentColumn method. The text related columns a just added using grid.addColumn

Now we want to enable multisort on the grid. By default the sorting indicators (up/down arrow) in the header are shown for the text based columns but not for the boolean values .

After adding sorting to the boolean column /component column (addComponentColumn(...).setSortable(true) the sorting indicators in the headers are shown, but the sorting itself is not performed when changing the sort direction (none / asc / desc) using the arrows in the header.

How can I make this work? Thanks in advance!

When you have custom logic for what's rendering in a column, then you also need to explicitly configure how sorting should be handled for that column.

If you're using in-memory data, then you do that using Column.setComparator. If you're using a backend data source, then you should instead use Column.setSortProperty and also ensure that the data provider actually considers the contents of Query.getSortOrders.

You can see an example of this in practice at https://cookbook.vaadin.com/sort-with-renderer.
