so I dont really understand the error it gives

edvin when you see this

val viewableItemsProperty = val viewableItemsProperty : ObjectProperty<ObservableList<TodoItem>> = SimpleObjectProperty(FXCollections.observableArrayList())
    var viewableItems by viewableItemsProperty

with error message

Error:(26, 26) Kotlin: Property delegate must have a 'getValue(MainViewController, KProperty<*>)' method. None of the following functions is suitable: 
public open fun getValue(): ObservableList<TodoItem>! defined in javafx.beans.property.ObjectProperty

can you enlighten us?

@ron You need to make sure you've imported

tornadofx.getValue

(and

tornadofx.setValue

)

Yes, that's right. I wonder if I can make the plugin hint about the missing imports somehow.. This has irritated me in the past, and it would be really cool if the imports were either just added automatically, or if you atleast got a hint about it.. Interesting..

I import tornadofx.*

(was making and having dinner, simple chicken from the oven)

yup that sorts it

a hint would have been very nice

I am getting soooo annoyed with this!

why does it just do what I want

FilteredList.setAll

throws an UnsupportedOperationException

I give up, going to do something else tonight, see if it triggers something

@ron FilteredList should just wrap another list, so you manipulate the list by manipulating the backing list that you passed to the FilteredList constructor 🙂 Or you can use SortedFilteredList from TornadoFX.

I know that

Thats not the problem

I want to manipulate the predicate

@User uploaded a file: Untitled

I think I just need to create a new FilteredList

@ron Just use SortedFilteredList 🙂

the original todo app does not have the list sorted

I don't think I understand the problem though. You should be able to update the predicate of a FilteredList by calling

setPredicate

again?

But when I see the above snippet I would think that you should just have a todoItemModel.filterByProperty, and no filterByProperty in the view.

@edvin you are my hero, setPredicate works

Haha, great 🙂

why did I not think of that

I know why.. you didn't check the documentation of FilteredList.. hehe

I would like to give some input on this app as soon as I have the time. This week will be pretty busy as well though, but after the operation on Friday I will have lots of time once the propofol wears off 🙂
