liferay - Liferay-Portlet 6.1.20 と ICEFaces 3.3.0: ace:fileEntry および icepush

Question

Liferay のポートレットを作成していて、ace:fileEntry コンポーネントが必要です。最終的に解決できた問題がいくつかありました。しかし今、私は理解できない問題に直面しています。

ace:fileEntry が含まれているビューページがオープンエンドの場合、プラスマイナス 90 秒後に「ネットワーク接続が中断されました」というメッセージがポップアップ表示され、ページをリロードする必要があります。いくつかの調査の後、ブラウザコンソールで次の行を見つけました。

[icepush.0086c.async-connection] closing previous connection...

[icepush.0086c.async-connection] empty response received
