rich：tabPanel不能和textarea一起工作

我想我有一個richFaces的bug。rich：tabPanel不能和textarea一起工作

我有一個帶有switchType ='ajax'和2（空）選項卡的tabPanel的簡單頁面，第一個選項卡只包含一個textarea，其值綁定到一個bean屬性，tabPanel不起作用。嘗試更改標籤時出現以下日誌消息：

info [11:31:56.919]: Received 'begin' event from <div id=form:j_id2114509110_7e08d99f ...> 
info [11:31:56.953]: Received 'beforedomupdate' event from <div id=form:j_id2114509110_7e08d99f ...> 
info [11:31:56.957]: Element error 
<error><error-name>javax.faces.component.UpdateModelException</error-name><error-message><![CDATA[org.apache.myfaces.view.facelets.el.ContextAwarePropertyNotWritableException: javax.el.PropertyNotWritableException: ResourceBundles are read-only]]></error-message></error> 
error[11:31:56.959]: Received '[email protected]' event from <div id=form:j_id2114509110_7e08d99f ...> 
error[11:31:56.961]: [200] undefined: undefined 
info [11:31:56.962]: Received 'complete' event from <div id=form:j_id2114509110_7e08d99f

當我刪除值綁定時，一切都按預期工作。 ~~另外通過輸入框更改textarea工作正常~~ 。

更新：我還得到了一個服務器錯誤與switchType = '服務器'：

這裏是工作代碼：

，在這裏我的環境：的Tomcat 6.0.18， Java 1.6.0_25，Win6.1 build 7601

有人遇到過這樣的問題，有沒有什麼解決辦法？

所以，我明白了！

這是一種錯誤，但在org.apache.myfaces.el.unified.resolver.ResourceBundleResolver版本2.0.9。

問題是我的屬性被命名爲「文本」，我也有一個名爲「文本」的資源包。此外在javax.el.CompositeELResolverorg.apache.myfaces.el.unified.resolver.ResourceBundleResolver之前是javax.el.BeanELResolver。

而org.apache.myfaces.el.unified.resolver.ResourceBundleResolver.setValue(ELContext context, Object base, Object property, Object value)方法不檢查基礎對象，只是尋找一個名爲屬性的資源包，在我的情況下它找到了一些東西和彭！例外！

它應該檢查(base != null)，然後離開。
