ClassCastException JBOSS con t:dataTable

[fe...@dbs.es]

Hi,

I'm a problem with jsf and jboss. You are these code with a dataTable de
tomahawk (project apache)

<t:dataTable renderedIfEmpty="false" value="#{managedBean[data].list}"
id="#{id}"
    rows="#{rows}" var="rowData"
    binding="#{ManagerBean.object}"
    styleClass="results" rowClasses="odd, even"
columnClasses="#{columnClasses}"
    headerClass="header" cellpadding="0" cellspacing="0" rules="cols"
frame="vsides">
<ui:insert />
</t:dataTable>

My ManagerBean.object is a Object class. The class code:

public String editEmployee() {
    try {
      System.err.println("object.getClass().getName():
"+object.getClass().getName());
      System.err.println("object.getClass().getName() 2" + (
(org.apache.myfaces.component.html.ext.HtmlDataTable )object
).toString());
...

The result is:
object.getClass().getName():
org.apache.myfaces.component.html.ext.HtmlDataTable

Launch ClassCastException in line
"System.err.println("object.getClass().getName() 2" + (
(org.apache.myfaces.component.html.ext.HtmlDataTable )object
).toString());".


Can you help me?

Thank you very much.


Como mi ingles es penoso lo traduzco a Español.

Hola,

Yo tengo un problema con Eclipse y JBoss. Yo tengo este código con una
tabla de tomahawk (proyecto apache)

<t:dataTable renderedIfEmpty="false" value="#{managedBean[data].list}"
id="#{id}"
    rows="#{rows}" var="rowData"
    binding="#{ManagerBean.object}"
    styleClass="results" rowClasses="odd, even"
columnClasses="#{columnClasses}"
    headerClass="header" cellpadding="0" cellspacing="0" rules="cols"
frame="vsides">
<ui:insert />
</t:dataTable>

Mi ManagerBean.object es de tipo Object. El codigo de la fuente es:

public String editEmployee() {
    try {
      System.err.println("object.getClass().getName():
"+object.getClass().getName());
      System.err.println("object.getClass().getName() 2" + (
(org.apache.myfaces.component.html.ext.HtmlDataTable )object
).toString());
...

El resultado:
object.getClass().getName():
org.apache.myfaces.component.html.ext.HtmlDataTable

Lanza una ClassCastException en la linea
"System.err.println("object.getClass().getName() 2" + (
(org.apache.myfaces.component.html.ext.HtmlDataTable )object
).toString());".


¿Puedes ayurdame?

Muchas gracias

Looks like a class loader issue.
Please search the archives, I think you have to delete the old JSF stuff
from jboss ... but I am not sure about this.

However, do not use the concrete class if not really required. Instead
in case of dataTable use UIData in your bean.

Ciao,
