[displaytag-user] How to highlight a row

[Steve Hostettler]

Hi,
 
I'am looking for an elegant way to select a row:
I have a request-scope bean named rowNum which is the number of the selected row and I 
need
to highlight this row.
 
By now i have:
<c:set var="currentRow" value="0" />
<c:set var="rowId" value="10" />
<c:set scope="page" var="rowClass" value="selectedRow" />
<display:table align="left" id="row" styleClass="odd" width="100%" name="listBean" >

<c:choose>
<c:when test="${rowId==currentRow}" >
<c:set scope="page" var="rowClass" value="selectedRow" />
</c:when>
<c:otherwise>
<c:set scope="page" var="rowClass" value="normalRow" />
</c:otherwise>
</c:choose>

<display:column class="<%=(pageContext.getAttribute("rowClass")).toString()%>" >
<c:out value="${currentRow}" />
<c:out value="${rowClass}" />
<%=(pageContext.getAttribute("rowClass")).toString()%> 
</display:column>

<display:column class="<%=(pageContext.getAttribute("rowClass")).toString()%>" 
property="comp_id.trxDate" width="10%" title="Datum" 
decorator="com.dataconnect.pms.online.decorator.ShortDateDecorator" />
<display:column property="comp_id.orgNod.orgNodeApplId" width="20%" title="Id" />
<display:column property="comp_id.orgNod.shortDescription" width="10%" 
title="Bezeichnung"/>
<display:column property="comp_id.acquirerId" width="10%" title="Acq." />
<display:column property="comp_id.cardId" width="10%" title="Karte" /> 
<display:column property="trxCount" width="10%" title="Anzahl" /> 
<display:column property="answerCode" width="10%" title="KV" /> 
<display:column property="eventCode" width="10%" title="ZT" /> 
<display:column property="trxType" width="10%" title="Typ" /> 
<display:column property="comp_id.cardId" width="10%" title="Fehlerbeschreibung" /> 

<c:set var="currentRow" value="${currentRow+1}" />
</display:table>

Ouput in HTML:

<td class="normalRow">
  10
  selectedRow
  selectedRow  
  </td>
<td width="10%" class="normalRow">23.12.2003</td>
<td width="20%">0087175</td>
<td width="10%">0087175_desc</td>

Don't know why but "<%=(pageContext.getAttribute("rowClass")).toString()%>"  is not 
computed each time (blue and red parts). You can change 
"<%=(pageContext.getAttribute("rowClass")).toString()%>" to 
"<%=(pageContext.getAttribute("currentRow")).toString()%>" it will always give "0" 
back.

Now the questions:

1) How can i make that "class" interprets the property each time?

2)Is there a solution to make this (select a row) with a decorator/table decorator ?

 

Thanks in advance
