how can I use .find with data class inserted into sealed class?

It's not really clear what you want to achieve.

find

works on collections.

@diesieben07okay look at this then

val itemsList = FXCollections.observableArrayList<itemModel>()

itemsList.find { it.id == 1 }

ItemModel

contains

val id: Int

so how should look working example if I’d put

ItemModel

into

sealed class

like this:

sealed class AnotherViewInstance {
    data class Item(val item: ItemModel): AnotherViewInstance()
}

Like this?

itemsList.find { it is AnotherViewInstance.Item && it.id == 1 }

Yes, thanks a lot, forgot about it. Is

when

also an option in case If i’d need to use it with another data class?

Sure
