Gerhard Petracek resolved DELTASPIKE-723.
-----------------------------------------
Resolution: Fixed
> Exception bypassing on JSF conversion errors
> --------------------------------------------
>
> Key: DELTASPIKE-723
> URL: https://issues.apache.org/jira/browse/DELTASPIKE-723
> Project: DeltaSpike
> Issue Type: Bug
> Affects Versions: 1.0.1
> Reporter: Sven Linstaedt
> Fix For: 1.0.3
>
>
> {{org.apache.deltaspike.jsf.impl.injection.proxy.DelegatingMethodHandler}} is
> not catching {{java.lang.reflect.InvocationTargetException}} from method
> invocations causing any kind of exceptions from converters and validators
> being thrown wrapped in InvocationTargetException.
> Especially when in comes to conversion this will cause
> {{javax.faces.component.UIInput.validate(FacesContext)}} fail to catch
> {{javax.faces.convert.ConverterException}} from any converters.
> To make things worse (and me scratching my head for several hours while
> trying to find out, how this "ConverterException" can bypass the before
> mentioned catch block from UIInput) BridgeExceptionHandlerWrapper returned by
> DeltaSpikeFacesContextWrapper is unfortunately only returning the unwrapped
> ConverterException to the application, so any trace of this catch block
> bypassing is cleaned up and therefore perfectly hidden from the application.
> To sum up: Current deltaspike releases > 1.0.0 are causing JSF based
> applications to fail on conversion errors, making these releases unusable.
> Possible solution: Catching the InvocationTargetException in
> DelegatingMethodHandler and rethrowing it's target exception will probably do
> the job, but as I peeked into the code MethodHandlerProxy and
> DelegatingMethodHandler seem to be a temporary solution, so maybe there is
> already another solution for this problem.
