Problem with Java 1.4 and BeanUtils and maybe PropertyUtils...

Brad Harris Mon, 05 Jan 2004 10:39:27 -0800

Hello, I will do my best to explain what's going on and hopefully someone can help me out. If more information is needed, please let me know.

Here is the situation. We're upgrading our servers to user java 1.4.1. We were previously running 1.3 A few of our web pages loop through collections and the user can modify something in the collection then save the changes. In 1.3 everything worked fine, no problems. However, when I switched to 1.4.1 (and tried 1.4.2) we started getting this error. I've tracked it down to this line in the PropertyUtils.java class: ----------- if(descriptor instanceof IndexedPropertyDescriptor) -----------

In 1.3 this was true. In 1.4 this returns false, and things go downhill from there. Please, any help would be terrific. Thank you.

Code snippets & error are below:

.jsp page w/code:

<% int counter = 0; %> <logic:iterate id="day" name="manualadjemplform" property="employeeWorkDay"> <bean:define id="idWorkDay" name="day" property="workDay" type="java.lang.String"/> <bean:define id="idCases" name="day" property="cases" type="java.lang.String"/> <bean:define id="idManualAdjId" name="day" property="manualAdjId" type="java.lang.String"/>

<%
 String baseProperty = "employeeWorkDay[" + (counter++) + "]";

 String workDayProperty = baseProperty + ".workDay";
 String commentProperty = baseProperty + ".comment";
 String manualAdjIdProperty = baseProperty + ".manualAdjId";
%>

<tr> <td align="left" nowrap> <bean:write name="day" property="workDay"/> <html:hidden name="day" property="<%=workDayProperty%>" value="<%=idWorkDay.toString()%>"> <bean:write name="day" property="workDay"/> </html:hidden> </td>

FormBean:
public class ManualAdjustmentEmployeeFormBean extends FormBean
{
   private List employeeWorkDay= new ArrayList();

   public void reset()

       this.employeeWorkDay = new ArrayList();

   }

   public void setEmployeeWorkDay(List employeeWorkDay)
   {

   }
