我有一個f：setPropertyActionListener在一個數據表內，並點擊一個命令按鈕，setpropertyaction監聽器沒有被調用。任何人看到我要去哪裏錯了？JSF setpropertyactionlistener不被調用

感謝

在我的豆我有以下的getter/setter

public EmailArticle getSelectedEmail() { 
     return selectedEmail; 
    } 

    public void setSelectedEmail(EmailArticle selectedEmail) { 

     this.selectedEmail = selectedEmail; 

    } 

public void updateAction(ActionEvent ae) { 
     selectedEmail.getActions().add(new EmailActions(emailAction, "testUser", actionDueDate)); 
     selectedEmail.merge(); 

    }

這裏的主要問題是調用順序，首先你actionListener被稱爲然後 f:setPropertyActionListener。

要解決此問題，請將您的actionListener更改爲action，並更新您的操作方法以返回字符串。

按鈕

<p:commandButton action="#{emailArticleBean.updateAction}" 
        value="Add Action" style="margin-left:5px;"> 
      <f:setPropertyActionListener value="#{email}" 
       target="# {emailArticleBean.selectedEmail}" /> 
    </p:commandButton>

updateAction

public String updateAction() { 
    selectedEmail.getActions().add(new EmailActions(emailAction, "testUser", actionDueDate)); 
    selectedEmail.merge(); 
    return null; 
}

您可以繼續使用您的ActionListener並通過selectedEmail給它（不使用F：setPropertyActionListener）。

按鈕

<p:commandButton actionListener="#{emailArticleBean.updateAction(email)}" 
       value="Add Action" style="margin-left:5px;"> 
</p:commandButton>

updateAction

public void updateAction(EmailArticle selectedEmail) { 
    selectedEmail.getActions().add(new EmailActions(emailAction, "testUser", actionDueDate)); 
    selectedEmail.merge(); 
}

沒有設置屬性爲@this沒有工作。 \t \t \t \t \t \t \t \t \t \t \t \t \t – user1107753

您的updateAction取決於selectedEmail？ –

你可以把你的updateAction方法... –
