Thomas Herzog commented on DELTASPIKE-218:
------------------------------------------
Yes the @ExceptionHandler annotation is on all subclasses.
The observer methods are invoked if event is not marked as handled and they do
define different ordinals
> ExceptionHandler observer chain is broken with same ordinal

> Key: DELTASPIKE-218
> URL: https://issues.apache.org/jira/browse/DELTASPIKE-218
> Project: DeltaSpike
> Issue Type: Bug
> Components: ExceptionControl-Module
> Affects Versions: 0.2-incubating
> Environment: Websphere 8.0.0.1
> Myfaces 2.1.1
> Myfaces-Codi 1.0.4
> Primefaces 3.1
> Reporter: Thomas Herzog
> Assignee: Jason Porter
> Fix For: 0.3-incubating
>
>
> When multiple observer methods are handling the same ExceptionEvent<T extends
> Throwable> with same exception type and do have the same ordinal or no one
> defined, then only one observer method gets invoked.
> This observer methods does not mark the event as handled, but the next ones
> do not get invoked.
> With ordinal defined, it works as expected.
> Example:
> -------------
> {code}
> @CoreExceptionMessage(...)
> class CoreException {...}
> @ModuleExceptionMessage(...)
> class ModuleException extends CoreException {...}
> handleCore void (@Handles ExceptionEvent<CoreException> event)
> { // Handles CoreException instances, determined via @CoreExceptionMessage
> annotation...}
> handleModule void (@Handles ExceptionEvent<CoreException> event)
> { // Handles ModuleException instances, determined via
> @ModuleExceptionMessage annotation...}
> {code}
> If annotation is not found the event gets not handled, so one of the next
> handlers shall do handle it.
> We do have an AbstractExceptionHandler which defines common work to do, and
> subtypes providing the @Handles annotated observer method and necessary data
> for the AbstractExceptionHandler such as annotation class.
