    have tried everything - what todo about bug in seam exceptio

    John McClain Newbie

      I have tried everuything listed here. There still seams to be a bug - In fact I built a dummy app to isolate the problem.
      Here is pages.xml:

      <?xml version="1.0" encoding="UTF-8"?>
      <pages>
       <exception ><redirect view-id="/genericErrorPage.xhtml"/></exception>
      </pages>
      

      here is my backing bean:
      package com.homeq.tst.action;
      import javax.ejb.Stateless;
      import org.jboss.seam.annotations.In;
      import org.jboss.seam.annotations.Name;
      import org.jboss.seam.annotations.Out;
      import org.jboss.seam.faces.FacesMessages;
      @Stateless
      @Name("EXCEPTTEST")
      public class ExceptionTest implements IExceptionTest {
       @In
       @Out
       FacesMessages facesMessages;
       public String tst() throws Exception {
       facesMessages.add("TestMessage");
       if (false)
       throw new Exception("testexception");
       else
       return "/genericErrorPage.xhtml";
       }
      }
      

      here is genericErrorPage.xhtml
      <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
       "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
      <html
       xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html">
      <head>
      <title>Error Page</title>
      </head>
      <body>
      <h:messages/>
      </body>
      </html>
      

      herre is mypage.xhtml
      <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
       "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
      <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html">
      <head>
      <title>hello world</title>
      </head>
      <body >
      HELLO WORLD
      <h:form >
      <h:commandButton action="#{EXCEPTTEST.tst}"/>
      </h:form>
      </body>
      </html>
      

      I goto mypage.seam, hit the commandButton . If I have set the test flag (see backing bean code if condition) to true, then I execute the exception and facesMessages gets blown away and "testexception" is displayed by genericErrorPage. If I set the testflag to false, then I simply render genericErrorPage.xhtml and the facesMessages shows the correct message. Why does facesMessages get blown away when exception is thrown?
