@amanda.hinchman-dominguez You should wrap the

imageview

inside

cellFormat

in

cache

to avoid recreating and reloading the images all the time btw 🙂 You should also do

override val root = borderpane { center {

etc, instead of first creating a borderpane, then overriding init to do

with(root)

. You can also call

action

instead of

setOnAction

. Just minor stuff, but wanted to mention it. About your problem, I haven't fully grasped the issue yet.
