NPE after reloading NavigationHandler
-------------------------------------
Key: EXTSCRIPT-38
URL: https://issues.apache.org/jira/browse/EXTSCRIPT-38
Project: MyFaces Extensions Scripting
Issue Type: Bug
Reporter: Jan-Kees van Andel
Assignee: Werner Punz
I see the explanation in the createMethodReloadingProxyFromObject JavaDocs, but
since the example crashes, I thought, let's file this issue anyway.
When a new NavigationHandler is loaded and I click on a button in the example
page, I get the following NPE (because _delegate is null):
java.lang.NullPointerException
