[jira] Created: (TAPESTRY-1004) NPE in
EventListenerAnnotationWorker
NPE in EventListenerAnnotationWorker
------------------------------------
Key: TAPESTRY-1004
URL: http://issues.apache.org/jira/browse/TAPESTRY-1004
Project: Tapestry
Type: Bug
Components: Annotations
Versions: 4.1
Environment: jdk 1.5.0_07
tapestry snapshot 4.1.0-20060711.165511-11
jetty 5.1.10
Reporter: Mark Reynolds
I hope this stack trace is enough. I will try to narrow it down to a reproduction recipe if need be. I am not using the new @EventListener annotation. I just dropped in the 4.1.0-SNAPSHOT as a replacement for 4.0.2 and hit this.

[jira] Commented: (TAPESTRY-1004) NPE in
EventListenerAnnotationWorker
Posted by "Jesse Kuhnert (JIRA)" <ta...@jakarta.apache.org>.

Jesse Kuhnert commented on TAPESTRY-1004:
-----------------------------------------
Sorry Mark. I thought I was going to get to this tonight but was offered free tasty steak for dinner and couldn't resist.
It's a scary exception as that particular type of worker should be guaranteed to have an EventListener annotation when performEnhancement() is called. If I can't create a test case that explains it tomorrow I might want more environmental info from you tomororw. (I will look at it first thing tomorrow and deploy a new snapshot if I succeed.)

-----------------------------------------
Thanks Mark, that does help to narrow it down. Sounds like an issue with the top level chain worker. I've added a temporary fix just to get you on your way again but am finally being forced to create a tapestry-test project so I can share testing resources. Shouldn't take very long. I'll update the ticket when I'm done.

[jira] Commented: (TAPESTRY-1004) NPE in
EventListenerAnnotationWorker
Posted by "Mark Reynolds (JIRA)" <ta...@jakarta.apache.org>.

Mark Reynolds commented on TAPESTRY-1004:
-----------------------------------------
@InitialValue may be the culprit. I tried to go to another page with doesn't have an @InitialValue annotation in the page itself, and then i got the same NPE during enhancement of a method in in my border component that has an @InitialValue annotation.
Error: Error enhancing method public abstract java.lang.String com.whatever.component.PageBorder.getBaseUrl(): java.lang.NullPointerException (basically the same stack trace as above).
Here are a couple methods from my page border class:
@InjectObject("infrastructure:request")
public abstract WebRequest getWebRequest();
@InitialValue("ognl:webRequest.contextPath")
public abstract String getBaseUrl();
