@edvin I thought the placeholder takes a node, not a string

it's not in the docs. ducks

it does take a node

@Ruckus You're probably right, didn't check 🙂 It makes much more sense with a Node though 🙂

@permalmberg https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/TableView.html#placeholderProperty

@permalmberg You can change

selectedComponentsProperty().addListener { observableValue, oldValue, newValue ->

to

selectedComponentsProperty().onChange {

@permalmberg Also, no need to do

stackpane {}.apply {}

, you can just do

stackpane { // put your code here }

.

I put it in

apply

to get access to

this

@permalmberg No need,

this

is the

StackPane

inside the builder.

I don't quite understand "The selectedComponentsProperty() change listener doesn't fire if the new hash map is empty or if the...". After the comment you add something to the

dummy

Map, but that won't affet the

selectedComponentsProperty()

will it?

@edvin Hm. I'm certain that I had to do that previously. No matter, works now.

@Ruckus I figured out how to change the star imports via the plugin. Next now is finding a hook where I can actually do it. I'd like to check it once when the plugin is initialized. Looking for something like an init callback.

@edvin Nice

@Ruckus I just found that I can register a

preloadingActivity

. That might do the trick. Just guessing as always with the plugin 🙂

@edvin

selectedComponentsProperty()

is tied to

selectedComponents

so yes, it does. And no, I don't add anything to the `dummy`map, I only exchange the map in

selectedComponents

. But don't mind that, it is quite possible that I've observed things wrongly.

@edvin That will be super useful

@permalmberg You do

dummy.put(UUID.randomUUID(), ComponentVM(PlaceHolderComponent()))

?

@Ruckus Fingers crossed!

@edvin Yes, but only once and it remains in that map. I might be missunderstanding what you're asking...

@edvin Removing

selectedComponents = dummy

breaks the

selectedComponentsProperty().onChange

event

Breaks it?

but that makes sense...it is no change, it's the same hashmap.

Yeah, I see what you're saying now.

What about just calling

selectedComponents.invalidate()

?

@Ruckus Haha, it worked on the first try 🙂

No such method, @edvin

@permalmberg

selectedComponentsProperty().invalidate()

sorry 🙂

@edvin Yeah, I figured you meant that, but still no such method.

or is that a 1.6 feature?

No, I thought

selectedComponentsProperty()

returned a Property, it should have that method, but it might be protected.
