[vata2999]

Hi,

I'm creating s:fileUpload dynamically but i've got this exception

Caused by javax.servlet.ServletException with message "#{addComponent.addcmp}:

 java.lang.ClassCastException org.jboss.seam.ui.component.html.HtmlFileUpload cannot be cast to 

org.jboss.seam.ui.component.html.HtmlFileUpload

code

import javax.faces.application.Application;
import javax.faces.context.FacesContext;
import javax.faces.component.UIComponent;
import javax.faces.component.html.HtmlInputText;
import org.jboss.seam.ui.component.html.HtmlFileUpload;


public class AddComponent {

     protected UIComponent component;

     
     public UIComponent getComponent() {
          return component;
     }


     public void setComponent(UIComponent component) {
          this.component = component;
     }


     public AddComponent() {
     }
     
     
     public String addcmp(){
          
          FacesContext fc = FacesContext.getCurrentInstance();
          Application app=  fc.getApplication();
//          HtmlInputText comp = (HtmlInputText)  app.createComponent("javax.faces.HtmlInputText");
          HtmlFileUpload comp = (HtmlFileUpload)  app.createComponent("org.jboss.seam.ui.FileUpload");
          
          
          component.getChildren().add(comp);
          return null;
     }
