Subject [jira] [Commented] (TAP5-1837) NPE on registry startup when using tapestry.use-external-spring-context in 5.3.2
Date Wed, 04 Jul 2012 07:34:36 GMT

    [ https://issues.apache.org/jira/browse/TAP5-1837?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13406333#comment-13406333

Lance commented on TAP5-1837:
-----------------------------

-1 from me

As I said before, I don't think your patch is correct... it should contain code like this:

BeanDefinition def = getBeanFactory().getBeanDefinition(beanName);
if (!def.isAbstract()) {
   // do stuff
}
