-----------------------------------------------------------

                 URL: https://jira.jboss.org/jira/browse/JBSEAM-3187
             Project: Seam
          Issue Type: Bug
          Components: Mail
    Affects Versions: 2.0.2.SP1
         Environment: jsf ri mojarra 1.2_08
            Reporter: Julien Buret
            Assignee: Pete Muir
            Priority: Minor


The bug is not present with jsf ri 1.2_04.
With 1.2_08, when a parameter in the mail template is null - for example if #{test} returns null, there is an exception like this :

java.lang.NullPointerException

The workaround I found is to subclass FaceletsRenderer like this

    @Override
    protected void renderFacelet(FacesContext facesContext, Facelet facelet) throws IOException {
        if(ApplicationAssociate.getCurrentInstance() == null) {
            new ApplicationImpl();
        }
        super.renderFacelet(facesContext, facelet);
    }
