Subject Re: Tapestry's OGNL with Hibernate
Date Tue, 01 Mar 2005 17:16:41 GMT
We use something like this:

          <tr height="20" jwcid="@Conditional" condition="ognl:
account.regimen != null" element="tr">
           <th class="titlecell"><font class="title">Regimen</font></th>
           <td class="normalcell" colspan="3"><font
class="normal">&nbsp;<span jwcid="@Insert" value="ognl:
account.regimen">MANCOMUNADA</span></font></td>
          </tr>

Regards

D.
