How to show error message in popup?

[mohammed24]

Hi experts,

I had created an interceptor for product validation for backoffice. Can anyone help me on how to display error message in popup or is there any wiki link to implement the same?

You could try this

 public class TextAction  implements CockpitAction<?, String> 
 
 
 
 protected void showErrorMessagebox(String messageLabel, ActionContext<? extends Object> ctx, final ActionResult<String> result, Exception ce, Object[] params) {
 
         String message = params == null ? ctx.getLabel(messageLabel) : ctx.getLabel(messageLabel, params);
         if (message == null) {
             message = messageLabel;
         }
         if (ce != null) {
             getLogger().warn(message + " " + ce.getMessage(), ce);
         } else {
             getLogger().warn(message);
         }
         result.setResultMessage(message);
         Messagebox.show(result.getResultMessage(), ctx.getLabel(MESSAGEBOX_TITLE_ERROR), Messagebox.OK, Messagebox.ERROR);
     }
