Re: EntityListIterator.hasNext() warning

Ján Valkovič
Yes, it is from custom lookup form and it's occured after click on
Search button.

That warning is caused by this code:
<#list embroideryColors as color>

 <#assign colorTableName =
delegator.findByPrimaryKey("AdColorTable",Static["org.ofbiz.base.util.UtilMisc"].toMap("colorTableId",color.colorTableId))>

 <tr <#if oddRow=-1>class="alternate-row"</#if> >
  <td class="button-col"><a
href="javascript:set_value('${color.colorId}')">${color.colorId}</a></td>
  <td>${colorTableName.get("colorTableName",locale)}</td>
  <td width="20" align="left" valign="top" style="background-color:#
${color.rgb}"></td>
  <td>${color.colorName}</td>
  <td>${color.rgb}</td>
  <td>${color.columnNr!""}</td>
  <td>${color.colorNumber!""}</td>
  <td>${color.description!""}</td>
 </tr>
 <#assign oddRow = oddRow*(-1)>
</#list>
"colorTableName" is EntityListIterator returned by service "performFind"

It's standard usage of <#list>, i think.  Similar code used in
non-lookup form works great, without warning.
