ClassCastException on form submit

[Vijay Chandran]

Dear friends,

When i submit a JSP page i get the following weird exception:

java.lang.ClassCastException: java.lang.String incompatible with org.apache.struts.action.ActionForm
org.apache.struts.util.RequestUtils.createActionForm(RequestUtils.java:777)
org.apache.struts.action.RequestProcessor.processActionForm(RequestProcessor.java:364)
org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:253)
org.apache.struts.action.ActionServlet.process(ActionServlet.java:1482)
org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:525)
javax.servlet.http.HttpServlet.service(HttpServlet.java:763)
javax.servlet.http.HttpServlet.service(HttpServlet.java:856)

I checked and double-checked the struts-config.xml file. All the entries are perfect. The action mappings everything are correct.

The following code is in my JSP an <html:form>, which displays a drop-down box from which user will select a value. getList(this) is a javascript which contains no errors.

    
<SELECT name="Name" id="name" onchange="getList(this);" />
  <OPTION value=""/>All <%=request.getSession(false).getAttribute("DetailsForm")==null ? "" : request.getSession(false).getAttribute("DetailsForm")%>

onsubmit i call another action and during this time, after selecting a value from the drop down i get the above exception. The form bean variables have matching data types.

Kindly provide your help.

Regards,
Vijay
