@pim This is basically the example for a

TreeView

from the tornadoFx guide, and I added a

textfield

and a

button

if you select a person you can change the name and with save the name will be committed and therefor visible in the

treeview

. I implemented the cellfactory my self since the default implementation (

cellformatter

) is not unbinding the

textProperty

when set to null like you pointed out before.
