2 years ago I currently fixed it by creating a custom:
class BindingAwareReversableObservableMapProperty<S, T>(viewModel: ViewModel, name: String?) : ReversableObservableMap<S, T>(viewModel, name) {
and
inline fun <reified PropertyType : T, reified T: ReversableObservableMap<*,*>,reified V: ItemViewModel<M>, reified M : Any, ResultType : PropertyType> V.bindReversableMap(property: KProperty1<M, PropertyType>, autocommit: Boolean = false, forceObjectProperty: Boolean = false, defaultValue: T? = null): ResultType {
But its really just a lot of boiler plate. Any other ideas on how a neater implementation would look like?
I have been working on an application for use during brainsurgery using this amazing framework for about a year now. BUt I have now encountered an issue that I have not been able to solve.
I made this custom implementation of an ObservableMapProperty which is backed by a reversed map (value,keys) with some custom impelmentations
class ReversableObservableMapProperty<K, V?> (map: ObservableMap<K,V?> = FXCollections.observableMap<K,V?>(hashMapOf())) : SimpleMapProperty<K, V?>(map)I have a Model :
class MappingModel() {val parcelHexagonMapProperty = ReversableObservableMapProperty<ParcelPoint,Hexagon?>()val parcelHexagonMap by parcelHexagonMapProperty}And and ItemViewModel:
class MappingModelView: ItemViewModel<MappingModel>() {val parcelHexagonMap = bind(MappingModel::parcelHexagonMapProperty)}On build however it throws the following error:
java.lang.ClassCastException: class tornadofx.BindingAwareSimpleMapProperty cannot be cast to class com.sasdashboard.ui.utils.ReversableObservableMap (tornadofx.BindingAwareSimpleMapProperty and com.sasdashboard.ui.utils.ReversableObservableMap are in unnamed module of loader 'app')at lineval parcelHexagonMap = bind(MappingModel::parcelHexagonMapProperty)Any idea what causes the issue? Is it due to my custom MapProperty not being accessible by TornadoFx? Might it be due to kotlin version (as I saw in another similar issue #12 . Any ideas on how to resolve it. I rely a lot on this easy binding of properties and delegation of Mapfunctions.
