[displaytag-user] Question

[Sven Siegfried Imfeld]

Hi,

 

I'm getting this Exception when I try to sort a table by any column that is handled by my tabledecorator class.

Here is my TableDecorator class:

 

package com.mo.control.util;

 

import java.util.Date;
import java.text.SimpleDateFormat;
import org.displaytag.decorator.TableDecorator;
import com.mo.model.bean.NotaFiscal;

 

public class MOTableDecorator extends TableDecorator {

 

   private SimpleDateFormat datefmt = null;

   public MOTableDecorator() {
     super();
     this.datefmt = new SimpleDateFormat( "dd/MM/yyyy" );
   }

 

   public String getDtEmissao() {
     Date dt = ( (NotaFiscal)this.getCurrentRowObject() ).getDtEmissao();
     return (dt != null) ? this.datefmt.format(dt) : "";
   }

 

   public String getDtEntrega() {
     return MOFormatter.getFormattedDeliveryDate((NotaFiscal)this.getCurrentRowObject());
   } 
  
}

 

 

[ERROR] RowSorter - -ObjectLookupException thrown while trying to fetch property
 "dtEmissao" during sort <Exception: [.LookupUtil] Error looking up prop
erty "dtEmissao" in object type "com.mo.control.util.MOTableDecorator"
