I have been trying to figure out how to highlight the selected row in a table. In my jsp I have jsp scriplet that can get access to the id of the row the displaytag library is creating. I want to compare it to the the id of the current row selected by the user ${currentNoteId}. Right now if the row id = 849 (hardcoded) the class "currentClass" is added to just that row of the table. I need to change the 849 for the {$currentNoteId} and I don't know how to do it. I am using java, Spring MVC. The jsp: ...

<%
request.setAttribute("dyndecorator", new org.displaytag.decorator.TableDecorator()  
{  
   public String addRowClass()  
   {  
      edu.ilstu.ais.advisorApps.business.Note row =               
      (edu.ilstu.ais.advisorApps.business.Note)getCurrentRowObject();      
            String rowId = row.getId();
            if ( rowId.equals("849") ) {
                return "currentClass";
            }
            return null;              
        }
    });
%> 

<c:set var="currentNoteId" value="${studentNotes.currentNote.id}"/>
...
<display:table id="noteTable" name="${ studentNotes.studentList }" pagesize="20"
  requestURI="notesView.form.html" decorator="dyndecorator">
    <display:column title="Select" class="yui-button-match" href="/notesView.form.html"
      paramId="note.id" paramProperty="id">
      <input type="button" class="yui-button-match2" name="select" value="Select"/>
    </display:column>
    <display:column property="userName" title="Created By" sortable="true"/>
    <display:column property="createDate" title="Created On" sortable="true" 
       format="{0,date,MM/dd/yy hh:mm:ss a}"/>
    <display:column property="detail" title="Detail" sortable="true"/>
</display:table>
...

This could also get done using javascript and that might be best, but the documentation suggested this so I thought I would try it. I cannot find an example anywhere using the addRowClass() unless the comparison is to a field already in the row (a dollar amount is used in the documentation example) or hardcoded in like the "849" id.

Thanks for any help you can provide.
