Non-Dependent scope specified on Decorator ------------------------------------------ Key: CDI-577 URL: https://issues.jboss.org/browse/CDI-577 Project: CDI Specification Issues Issue Type: Clarification Components: Decorators Affects Versions: 1.0, 1.2.Final Reporter: Emily Jiang Priority: Minor In CDI specification, there lacks a clarification about what will happen if a scope other than Dependent specified on Decorators/Interceptors. At the moment, if the RequestScoped is specified on a decorator, Weld throws NPE. I talked to Martin. Martin logged https://issues.jboss.org/browse/WELD-2085 to fix this. It is better for the spec to clearly define the behaviour. Obviously, the lifecycle of interceptors/decorators are dependent on the bean instance they decorate. The spec should specify clearly what should happen if a scope other than Dependent is specified on decorators/interceptors. How about add the following on the spec: If an interceptor or decorator specifies any scope other than Dependent, the container automatically detects the problem and threats as a definition error.
