I just hit Tab on an empty tree by accident. Turns out it results in a division by zero because the submorphs list is empty.
Kind regards, Jakob

Hi Christoph,
I don't have my empty tree view any more, but when I load your method change and run the example you gave in the commit message, there is no error any more.
Kind regards, Jakob

Hello all,
I just hit Tab on an empty tree by accident. Turns out it results in a division by zero because the submorphs list is empty.
Kind regards, Jakob
