EL in <sec：authorize>訪問屬性

Question

在訪問屬性中不能使用EL嗎？我不喜歡硬編碼標籤中的角色名稱，而是想使用常量。但它拋出一個異常說：

org.apache.jasper.JasperException: abc.jsp(19,4) According to TLD or 
attribute direc tive in tag file, attribute access does not accept 
any expressions 

Here is what I have in jsp(using unstandard taglib for constants): 

<%@taglib uri="http://jakarta.apache.org/taglibs/unstandard-1.0" prefix="un"%> 
<un:useConstants className="com.xxx.PrivilegeConstants" var="privilege" /> 
..... 

<sec:authorize access="hasRole('${privilege.USER_ROLE}')"> // throwing ex here 
    security content here.... 
</sec:authorize>  

Is there any other alternative? Thanks in advance...

看起來支持稍後添加。請參閱JIRA here。我想，使用增加這種支持的版本應該可以工作。
