Mutable reactive maps being mapped to each other

metaRxDictExample1.scala

  protected val controlMap: Dict[TableIndex, ControlTypes] = Dict()
  protected val textInMap: Dict[TableIndex, String] = Dict()
  protected val textMap: Dict[TableIndex, String] = Dict()
  
  val controlToText = controlMap.changes.attach{
    case delta: Dict.Delta.Insert[TableIndex, ControlTypes] =>
      val te = implicitly[ControlTableEntry[ControlTypes, String]]
      textMap(delta.key) = te.getEntry(delta.value)
    case delta: Dict.Delta.Update[TableIndex, ControlTypes] =>
      val te = implicitly[ControlTableEntry[ControlTypes, String]]
      textMap(delta.key) = te.getEntry(delta.value)
    case delta: Dict.Delta.Remove[TableIndex, ControlTypes] =>
      textMap.removeIfExists(delta.key)
    case delta: Dict.Delta.Clear[TableIndex, ControlTypes] =>
      textMap.clear()
  }
  
  val textIntoText = textInMap.changes.attach{
    case delta: Dict.Delta.Insert[TableIndex, String] =>
      textMap(delta.key) = delta.value
    case delta: Dict.Delta.Update[TableIndex, String] =>
      textMap(delta.key) = delta.value
    case delta: Dict.Delta.Remove[TableIndex, String] =>
      textMap.removeIfExists(delta.key)
    case delta: Dict.Delta.Clear[TableIndex, String] =>
      textMap.clear()
  }

Use the following instead:

protected val textMap: Dict[TableIndex, String] =
    textInMap.map[String]((k,v) => v).buffer
