@amanda.hinchman-dominguez JavaFX observable properties must not be confused with Kotlin properties, observable or otherwise 🙂 You don't need any library, this functionality comes with JavaFX, and is just leveraged in TornadoFX to make it super easy to bind ui components to properties 🙂

@amanda.hinchman-dominguez Read this: https://edvin.gitbooks.io/tornadofx-guide/content/part2/Property%20Delegates.html#javafx-property-delegate

And use the alternative syntax. We should update the guide so it only describes this syntax, really.

Is there a way to deselect a list item / row (in either TableView or ListView) when clicking on a blank space? For example, I may only have two items in the list, but the list takes up enough space for 10 (there are 10 rows, 8 of them are blank). When either of the two items is clicked, it is selected. But when any of the empty list spaces are clicked, the last selection remains instead of being cleared.

Another alternative would be allowing the blank rows to be selected - is this possible?

@edvin so it turns out I already had a JSON model set up just like the example you gave, but I don't think the bind for textfields considers properties set up in JsonModel classes observable

it looks like you did use an ItemViewModel after all in your kitchensink example:

in your class

CustomerWizard

you use model.property in

textfield(model.property)

- is that supposed to be the way to bind jsonmodel properties?

@amanda.hinchman-dominguez

titleProperty

should be a JavaFX property for you to be able to bind it to a TextField's textProperty.

amanda.hinchman-dominguez

check out my snippet: the title seems to have that?

amanda.hinchman-dominguez

02/05/2018, 2:59 AM

below that is the error message

abhinay

02/05/2018, 2:59 AM

Can you add

TileBuilder

class as snippet or link to it?

@edvin showed me a example, also referred to in the documentation explaining that these properties should be observable. However, IntelliJ does recognize the property as such

amanda.hinchman-dominguez

02/05/2018, 3:03 AM

as described in the error message

@abhinay if you check out the kitchensink links I posted, you'll see that an itemviewmodel is added to the jsonmodels and used inside textfields

abhinay

02/05/2018, 3:10 AM

I think your issue is that you are not using the declared

titleProperty

abhinay

02/05/2018, 3:11 AM

i.e. create a

TileBuilder

instance and then use the

titleProperty

variable.

abhinay

02/05/2018, 3:12 AM

Copy code

val tileBuilder = TileBuilder()
...
fieldset("Personal Information") {
    field("Color") {
        textfield().bind(tileBuilder.titleProperty)
    }
}

amanda.hinchman-dominguez

I did try that as well, but for some reason it does not recognize that

amanda.hinchman-dominguez

02/05/2018, 3:18 AM

I'm kind of at a loss, and the kitchensink version seems to work

amanda.hinchman-dominguez

02/05/2018, 3:18 AM

it doesn't recognize

tileBuilder.title

either

abhinay

02/05/2018, 3:19 AM

Not

title

. Use

titleProperty

amanda.hinchman-dominguez

02/05/2018, 3:19 AM

I did do that.

amanda.hinchman-dominguez

02/05/2018, 3:19 AM

Didn't work

abhinay

02/05/2018, 3:20 AM

Let me create a quick sample for you and then I can explain you why it was not working earlier.
