Seam throws NPE when a component without a @Name is specified in components.xml ------------------------------------------------------------------------------- Key: JBSEAM-665 URL: http://jira.jboss.com/jira/browse/JBSEAM-665 Project: JBoss Seam Issue Type: Bug Components: Core Affects Versions: 1.1.0.GA Environment: Win XP Pro Java 1.5.0 Tomcat 6.0.7 Reporter: Mike Quilleash Assigned To: Shane Bryzak Fix For: 1.1.1.GA Attachments: Initialization.diff Example line in components.xml <component class="com.xxx.ElementDetail"/> Class ElementDetail does not have a @Name (which it should) but class Initialization method installComponentFromXmlElement() throws an NPE on this line. name = clazz.getAnnotation(Name.class).value(); Would be nice to check for the null condition and throw a more descriptive exception of the problem. e.g Name nameAnnotation = clazz.getAnnotation( Name.class ); if ( nameAnnotation == null ) throw new IllegalArgumentException( "Component class " + class.getName() + " requires a @Name annotation or it's components.xml reference requires a name attribute" ); name = nameAnnotation.value();
