モデルのArrayCollectionがUIで更新されない問題をデバッグしています（新しいデータで表示されていても）。
そのモデルを他のコンポーネント、つまりトップレベルのコンポーネントに渡すと問題が発生するのではないかと思いました。
たとえば、トップレベルのモデルは次のとおりです。
[Bindable]
private var meetingInfo:MeetingInfoModel;
ここで、同じクラスのコンポーネントに渡します。
<meetingViewStack:MeetingViewStack id="mainPanelContainer"
newAttachmentsList="{meetingInfo.newAttachmentList}"
meetingInfo="{meetingInfo}"
currentState="{getPanelState(currentState)}"
inCreateMeeting="false"
includeIn="runSinglePanel, runDoublePanel"
height="100%"
width="100%"
/>
そして、MeetingViewStackコンポーネントでそのプロパティを宣言する方法は次のとおりです。
[Bindable]
public var meetingInfo:MeetingInfoModel = MeetingInfoModel.getInstance();
MeetingViewStackでバインディングが正しく機能する必要がありますか？そのプロパティが別のコンポーネントによって渡されたとしても。
つまり、私はそれを渡す必要は本当にありません。それはモデルであり、そこで宣言することができます。
役立つヒントをありがとう！
アップデート：
MeetingInfoプロパティを更新したときに、セッターが呼び出されることを確認しました。ただし、meetingInfoモデルの配列コレクションを更新しても呼び出されません。
meetingInfo.docsAndAttachmentsList.sort = nameSort;
meetingInfo.docsAndAttachmentsList.refresh();
どうすればそれを機能させることができますか？それが私が本当に探しているものです。
MeetingInfoModelクラスは次のとおりです。
