問題に続いて記念品は、コードが正しく動作する最初の時間のために初期化されている場合）
1を発生します。しかし、データを変更せずにviewPartを再度開くと、エラーが発生します。
2）私はすべての値をハッシュマップに保存しました。データを復元すると、最初の3つの値しか得られず、残りの値は表示されません。私がすべてのデータよりも数字を使うと、適切にデータが得られます。それに対する解決策はありますか？
3）私のfillTableRoWData（）メソッドでは、2つのif条件が実行されたときに、すべてのリスナーが2番目の条件にのみ当てはまります。条件の2つの間でリスナーを移動する方法。
viewpartを実装します。まさにあなたは何を保存したいですか？ –
@ greg-449私は編集を行いました。私は、getTableメソッドが呼び出されたときに表示されているデータを保存します。 savestateメソッドを使用してどのように保存できますか？私は私のviewpartに保存されているデータを取得していません。 –
あなたのコードは 'saveState'メソッドで保存していますか？このコードを書くのはあなた次第です。 –
