Support for "self" injection or intercepted self invocation ----------------------------------------------------------- Key: CDI-414 URL: https://issues.jboss.org/browse/CDI-414 Project: CDI Specification Issues Issue Type: Bug Components: Resolution Reporter: arjan tijms Fix For: 2.0 (discussion) Many features of CDI and EJB work by means of a proxy that intercepts calls and adds 'aspects'. In Java it's however not possible to decorate the {{this}} pointer, so methods called on the same bean instance from within a method in the bean do not get their 'aspects' applied. This is a well known limitation, but in EJB it's possible to work around this by injecting a bean into itself. E.g. {code} @Stateless public class Foo { @EJB private Foo self; // ... } {code} Also see http://adam-bien.com/roller/abien/entry/how_to_self_invoke_ejb Unfortunately using CDI and {{@Inject}} this doesn't work. Weld for instance fails the deployment and logs: {noformat} WELD-001443 Pseudo scoped bean has circular dependencies. {noformat} See also: http://adam-bien.com/roller/abien/entry/inject_vs_ejb Although there are workarounds, it would be great if {{@Inject}} in combination with CDI could support self injection as well. With that projects migrating from {{@EJB}} to {{@Inject}} can do so more easily and the capability can be convenient for new projects as well (e.g. calling two separate {{@Transactional}} methods from a single method without being required to create a new bean).
