Using a dynamic property inside a tag

[sw...@datachest.com]

I have the following code inside my action class.

            java.util.List al = fm.getFilesByUserName(conn,"SCOTT");
            request.setAttribute("files.count", new Integer(al.size()) );
            request.setAttribute("files.pageSize", new Integer(3) );
            request.setAttribute("userFiles", al );

Now in my JSP page I can do

<H1> Files per page is  <%= request.getAttribute("files.pageSize").toString
() %> </H1>

but when I try and use this value inside my logic iterate tag as below.

<logic:iterate id="element" name="userFiles" length="<%=
request.getAttribute("files.pageSize").toString() %>" >
  <tr class="highlight">
 .....

I get the following error.
org.apache.jasper.compiler.ParseException: /files.jsp(76,93) Attribute
files.pageSize has no value
             at
org.apache.jasper.compiler.JspReader.parseAttributeValue(JspReader.java:563)

             at
org.apache.jasper.compiler.JspReader.parseTagAttributes(JspReader.java:681)

Can someone point me in the right direction.

Searching the archives and looking on the internet didn't help me much as
that is where I got the code from.

Appologies if this is posted in HTML we are using Lotus Notes and I am not
sure how to subimt in plain text. (I miss outlook)

Thanks,
Scott.

You have to escape the quotes with backslash:

<logic:iterate id="element" name="userFiles" 
	length="<%=request.getAttribute(\"files.pageSize\").toString() %>" >
