@edvin Yeah that's true. But in some cases I have some values in my viewModel which should be presented differently in the view so I use a

stringBinding

to transform the value into the desired format.

@nimakro I do the same 🙂

@nimakro Very happy to hear about the guide - we need to cover more of the hidden gems 🙂 It doesn't have to be much, just a mention and a small example.

@edvin When tracing my way through a table's

bindselected

, in

ItemControls

in

fun TableView<T>.bindSelected

on line 462. The debugger cannot resolve

selectionModel.selectedItemProperty()

(that is the current code), but it can resolve

selectionModelProperty().value.selectedItemProperty()

I noticed this because my breakpoint on line 463 inside the listener were never being reached.

What is the proper way of using a list in an

ItemViewModel

(to bind to a

ListView

for example)?

I know I've done it before, but I can't remember where or how.

wouldn't it be like

listview(viewModel.someListValuedProperty) {
	// ...
}

or maybe

listview(viewModel.someListValuedProperty.value) {
	// ...
}

I can't figure out the bind statement in the

ItemViewModel

That may work though.

Isn't there a way to have the IVM contain a

ListProperty

?

Oh you mean how to define

someListValuedProperty

Indeed. Even

val internalReferences: ListProperty<Reference> = bind { SimpleListProperty(item?.references) }

fails at runtime with a class cast exception.

maybe this:

class Foo (
		stringList: List<String>? = null
) {
	var stringList by property(stringList)
	fun stringListProperty() = getProperty(Foo::stringList)
}

or maybe

class Foo (
		stringList: List<String>? = listOf<String>()
) {
	var stringList by property(stringList)
	fun stringListProperty() = getProperty(Foo::stringList)
}

For various reasons, I'd prefer not to change the type of my list.

I have

val tracks = FXCollections.observableArrayList<Track>()

in my model and then

val tracks = bind(Album::tracks)

in my IVM

Well I just used String as an example

not sure if that is what you are looking for... i don't bind to an listview, but i do bind to a tableview...

@jchildress How do you bind it to the TableView?

checking

'val currentAlbum: AlbumModel by inject()' then ' tableview(currentAlbum.tracks)' am I binding to the Model and not the IVM?

You are. Let me see why it's not working for me.

Ah, I found my issue (PEBKAC). It's going to be a pain to fix

Thanks

sorry... good luck

I got it, thanks again.

@Ruckus Something we can do in the framework to alleviate the pain? 🙂

@kastork I've noticed lots of glitches with the IDEA debugger when it comes to Kotlin classes, especially with observable values. It gets confused when there is an accessor function and a field for the property I believe.
