Tomas Remes created DELTASPIKE-863:
--------------------------------------
Summary: NPE when invoking proxy for custom jsf converter
Key: DELTASPIKE-863
URL: https://issues.apache.org/jira/browse/DELTASPIKE-863
Project: DeltaSpike
Issue Type: Bug
Components: Core, JSF-Module
Affects Versions: 1.3.1
Environment: EAP 6.4.0.Beta, Weld 1.1.28.Final
Reporter: Tomas Remes
I am not sure whether it's during invoking or creating proxy class but it
manifests with following exception. The problem is that
org.apache.deltaspike.core.util.proxy.invocation.DelegateManualInvocationHandler#proceedOriginal
is called before any delegateInvocationHandler is actually set (see
org.apache.deltaspike.core.util.proxy.DeltaSpikeProxyContextualLifecycle#create):
