@Handles parameter should be permitted in any parameter position
----------------------------------------------------------------
Key: SEAMCATCH-39
URL: https://issues.jboss.org/browse/SEAMCATCH-39
Project: Seam Catch
Issue Type: Bug
Components: Core Implementation
Affects Versions: 3.0.0.Alpha3
Reporter: Dan Allen
Assignee: Jason Porter
Fix For: 3.0.0.Alpha4
To be consist with CDI observers, the @Handles parameter should be allowed to
be used in any position in the list of method arguments. The only restriction
is that there is exactly one parameter annotated with @Handles (and it must be
of type CaughtException).
Here is the relevant section on observer methods for reference:
"10.4.2. Declaring an observer method
An observer method may be declared by annotating a parameter
@javax.enterprise.event.Observes. That parameter is the event parameter. The
declared type of the parameter is the observed event type. If a method has more
than one parameter annotated @Observes, the container automatically detects the
problem and treats
it as a definition error."
So we should allow:
public void handle(BeanManager, @Handles CaughtException<Exception> ex) {}
