Xibin Zeng commented on BEEHIVE-1051: ------------------------------------- Correction - the name of the interface is org.apache.beehive.controls.spi.svc.Interceptor > Control Interceptor SPI missing throwable for event dispatching > --------------------------------------------------------------- > > Key: BEEHIVE-1051 > URL: http://issues.apache.org/jira/browse/BEEHIVE-1051 > Project: Beehive > Type: Bug > Components: Controls > Versions: 1.0.1 > Environment: ALL > Reporter: Xibin Zeng > > There are 4 methods on the > org.apache.beehive.controls.spi.svc.Interceptorinterface. > For a control operation, preInvoke/postInvoke are called before and after the > operation, respectively. The postInvoke callback contains the exception that > the operation threw. For preEvent/postEvent, which is called before and after > control event dispatching, however, there is no exception information passed > to the postEvent callback. This looks inconsistent to me. > Imagine that you need to enforce J2EE transaction behaviors using these > interceptors (i.e. rollback a transaction in case of a system exception), you > will need to know what exception has been generated as the result of invoking > the operation or event callback. You could do this for your control > operations, but not event callbacks, since the exception caught during event > callback isn't passsed to the interceptor. > In my humble opinion, I think we should make preInvoke/postinvoke and > preEvent/postEvent API's symmetric. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
