tag file handler generation with array attributes

           Summary: tag file handler generation with array attributes
           Product: Tomcat 5
           Version: 5.0.3
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Jasper2
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: crofton-2003@bigfoot.com


I have written a tag file with a attribute of string array. just like this:
<%@ attribute name="columns" type="java.lang.String[]"%>

I wrote a JSP file to invoke this tag file. the variable "columns" has been 
set.
1. <tags:test columns="<%= columns %>"/>
When I pass attribute in the JSP file using scriptlet, it's ok.

2. <tags:test columns="{columns}"/>
But when I pass attribute using EL, something will be wrong, The following is 
the error statement reported by japser compiler when compiling the JSP file:
setColumns(([Ljava.lang.String;) 
org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate("${columns}", 
[Ljava.lang.String;.class, (PageContext)pageContext, null, false));
