Hi there,
My form backing object gives a JspTagException and I don't get why.

I read up on this and I could only get one explanation, my commandName and my spring:bind are different. But this is not the case:
Bean
<bean id="tranReportValidator" class="co.za.easypay.billpayment.validator.TranReportVali dator"/>
<bean id="tranReport" class="co.za.easypay.billpayment.controller.TranReportCon troller">
<property name="sessionForm"><value>true</value></property>
<property name="commandName"><value>formview</value></property>
<property name="commandClass"><value>co.za.easypay.billpayment.formview.FormView</value></property>
<property name="validator"><ref bean="tranReportValidator"/></property>
<property name="formView"><value>tranReport</value></property>
<property name="successView"><value>TranReport.BPS</value></property>
</bean>
spring:bind
<spring:hasBindErrors name="formview">
<font color="red"><u>Please fix all errors!</u></font>
</spring:hasBindErrors>
<spring:bind path="formview.recName">
<td><input:select name="${status.expression}" attributes="${recNameAttributes}" options="${recName}" default="D" />
<font color="red"><c:out value="${status.errorMessage}"/></font>
</td>
</spring:bind>
could it be because I am changing the form view in the controller?
if((request.getParameter("searchBy") != null)&&(request.getParameter("searchBy").equals("2"))){
jspxName = "tranGroup";
return new ModelAndView(jspxName,myModel_);
