已知問題

Dispatcher重新擷取失敗

將Dispatcher 4.1.5與較新版本的Jetty搭配使用時,重新擷取可能會在等候請求逾時後,導致「無法從遠端伺服器接收回應」。

使用Dispatcher 4.1.6或更新版本將可解決此問題。

從CQ 5.4升級後無法存取論壇貼文

如果論壇是在CQ 5.4上建立且張貼的主題,然後網站升級至AEM 5.6.1或更新版本,嘗試檢視現有貼文可能會導致頁面錯誤:

非法模式字元'a'
無法在此伺服器上向/content/demoforums/forum-test.html提供請求,且日誌包含以下內容:

20.03.2014 22:49:35.805 ERROR [10.177.45.32 [1395380975744] GET /content/demoforums/forum-test.html HTTP/1.1] com.day.cq.wcm.tags.IncludeTag Error while executing script content.jsp
org.apache.sling.api.scripting.ScriptEvaluationException:
at org.apache.sling.scripting.core.impl.DefaultSlingScript.call(DefaultSlingScript.java:388)
at org.apache.sling.scripting.core.impl.DefaultSlingScript.eval(DefaultSlingScript.java:171)

問題是com.day.cq.commons.date.RelativeTimeFormat的格式字串在5.4和5.5之間更改,以便不再接受"ago"的"a"。

因此,使用RelativeTimeFormat()API的任何程式碼都需要變更:

  • 從: final RelativeTimeFormat fmt = new RelativeTimeFormat("r a", resourceBundle);
  • 至: final RelativeTimeFormat fmt = new RelativeTimeFormat("r", resourceBundle);

製作和發佈時失敗不同。 在製作時,會以靜默方式失敗,而只是不顯示論壇主題。 發佈時,會在頁面上擲回錯誤。

如需詳細資訊,請參閱com.day.cq.commons.date.RelativeTimeFormat API 。

常見問題

記錄中的警告:已棄用的Handlebars

在啟動期間(不是第1次 — 但之後的每次),記錄中可能會顯示下列警告:

  • 11.04.2014 08:38:07.223 WARN [FelixStartLevel]com.github.jknack.handlebars.Handlebars Helper 'i18n' 已由 com.adobe.cq.social.handlebars.I18nHelper@15bac645

此警告可以安全地忽略,因為SCF使用的jknack.handlebars.Handlebars附帶了自己的i18n輔助實用程式。 啟動時,會以AEM專用的i18n helper取代。 此警告由第三方程式庫產生,以確認現有協助程式的覆寫。

記錄中的警告:OakResourceListener processOsgiEventQueue

張貼許多社交社群論壇主題,可能會產生來自OakResourceListenerprocessOsgiEventQueue的大量警告和資訊記錄。

這些警告可以安全地忽略。

日誌中出錯:IndexElementFactory的NoClassDefFoundError

將AEM 5.6.1 GA升級至最新cq-socialcommunities-pkg-1.4.x或AEM 6.0會在啟動期間導致記錄檔中發生錯誤,條件會自行解決,重新啟動時未看到錯誤即為證明。
