Hi,
I'm having some problems implementing the examples used to create dynamic links
using a table decorator.
I have the following setup:
I have a jsp page that displays my table (data is pulled from a database and
put into a RowSetDynaClass):
<%
RowSetDynaClass new_ncs = ActionViewTables.newNCTableSC(sdid_string);
%>
<% request.setAttribute("new_ncs_sc", new_ncs); %>
<display:table name="requestScope.new_ncs_sc.rows" id="row"
decorator="teska.displaytag.Wrapper">
<display:column property="sfdid" title="ID" sortable="true"/>
<display:column property="level" title="Level" sortable="true"/>
<display:column property="form_name" title="Form Name" sortable="true"/>
<display:column property="last_name" title="System Coordinator"
sortable="true"/>
<display:column property="date_submitted" title="Date Submitted"
sortable="true"
decorator="teska.displaytag.LongDateWrapper"/>
<display:column property="scncviewlink" title="Take Action" />
</display:table>
I have created my own wrapper class as follows:
package teska.displaytag;
/**

import java.text.DecimalFormat;
import java.util.*;
import org.apache.commons.lang.time.FastDateFormat;
import org.displaytag.decorator.TableDecorator;
/**

public class Wrapper extends TableDecorator{
/**
* FastDateFormat used to format dates in getDate().
*/
private FastDateFormat dateFormat;
/**
* DecimalFormat used to format money in getMoney().
*/
private DecimalFormat moneyFormat;
/**
* Creates a new Wrapper decorator who's job is to reformat some of the
data
located in our TestObject's.
*/
public Wrapper(){
super();
this.dateFormat = FastDateFormat.getInstance("MM/dd/yy");
//$NON-NLS-1$
this.moneyFormat = new DecimalFormat("$ #,###,###.00");
//$NON-NLS-1$
}
public String getScncviewlink(){
ListObject currRowObject = (ListObject)getCurrentRowObject();
String sfdid = (currRowObject.getSfdid());
return "\<a href=\"/displayView.jsp?sfdid=" + sfdid +
"\"\>View\</a>";
}
/**
* Test method which always returns a null value.
* @return <code>null</code>
*/
public String getNullValue(){
return null;
}
/**
* Returns the date as a String in MM/dd/yy format.
* @return formatted date
*/
/*
public String getDate(){
return
this.dateFormat.format(this.getCurrentRowObject().getDate());
}
*/
/**
* Returns the money as a String in $ #,###,###.00 format.
* @return String
*/
/*
public String getMoney(){
return
this.moneyFormat.format(this.getCurrentRowObject().getMoney());
}
*/
}//close class
When I run this code I get the following error message:
500 Servlet Exception

My questions are:
1: Where do I get the ListObject class and where do I put it to have ot work
- does it need additional classes to work?
2. I'm not clear how I access the value of sfdid (the first value in each row
of my RowSetDynaClass). The examples talk about getId() and getListIndex(),
but it is not at all clear which one is the value of a specific object - if
either one of them actually are that.
Please let me know if I can provide any additional info
Thanks,
Courtenay
