[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-4032) Page scope throws exception when setting null value

Page scope throws exception when setting null value --------------------------------------------------- Key: JBSEAM-4032 URL: https://jira.jboss.org/jira/browse/JBSEAM-4032 Project: Seam Issue Type: Bug Components: Core Affects Versions: 2.1.1.GA Reporter: Matthew Lieder Assignee: Norman Richards Fix For: 2.1.2.CR1 The following code will cause an unhelpful NPE to be thrown by JSF when the factory is accessed: @Name("someComponent") @Scope(ScopeType.PAGE) public class SomeComponent implements Serializable { @Factory("someVar") public String getSomeVar() { return null; } } While I believe I remember reading that using that particular type of factory method on a page-scoped component isn't supported (supported by the fact that removing the @Scope makes it work), the exception should at least be somewhat helpful in debugging the problem. NPE's with no messages are about as unfriendly as one can get.
