[JBoss JIRA] (CDI-490) Clarify what happens when an interceptor/decorator is enabled using both @Priority and beans.xml

[ https://issues.jboss.org/browse/CDI-490?page=com.atlassian.jira.plugin.sy... ] Martin Kouba commented on CDI-490: ---------------------------------- For options 2) and 3) there should be also a big warning about the fact, that the ordering may be different on CDI 1.0 and CDI 1.1+. For option 2), consider the following beans.xml: {code} <interceptors> <class>com.acme.myfwk.TransactionInterceptor</class> <class>com.acme.myfwk.LoggingInterceptor</class> </interceptors> {code} and interceptor classes: {code} class TransactionInterceptor {} @Priority(100) class LoggingInterceptor {} {code} The ordering would be: * CDI 1.0 ## TransactionInterceptor ## LoggingInterceptor * CDI 1.1+ ## LoggingInterceptor ## TransactionInterceptor To fix this a user would either have to add {{@Priority}} to relevant interceptor classes or modify {{javax.enterprise.inject.spi.AfterTypeDiscovery.getInterceptors()}}. > Clarify what happens when an interceptor/decorator is enabled using both @Priority and beans.xml > ------------------------------------------------------------------------------------------------ > > Key: CDI-490 > URL: https://issues.jboss.org/browse/CDI-490 > Project: CDI Specification Issues > Issue Type: Clarification > Components: Decorators, Interceptors > Affects Versions: 1.2.Final > Reporter: Jozef Hartinger > > Suppose an InterceptorA has @Priority and is also listed in the beans.xml file of a particular BDA.

Re: [cdi-dev] More CDI integration on JSF 2.3

by Werner Keil

I suggested exactly that when I spoke to Manfred and Ed during a combined MVC/Servlet 4 kick-off at JavaOne;-) Given JSF Flow in 2.2 already took quite some "inspiration" from Spring (and then VMWare had at least 2 EG members) while I don't know, if somebody from Pivotal joins the MVC EG, it will likely reassemble Spring MVC quite a bit. And Events are among key Features of CDI it shall benefit from. I recently joined the JMS 2.1 EG and its proposal also aims at further Integration with CDI 2: https://jcp.org/en/jsr/detail?id=368 P.s.: JMS Spec Lead Nigel Deakin said, he expects to be at DevoXX BE, so maybe those of you who are there could hitch up with him, too;-) Cheers, Werner Keil | JCP Executive Committee Member, JSR 363 Co Spec Lead | Eclipse UOMo Lead, Babel Language Champion | Apache Committer | Java Godfather Twitter @wernerkeil | @UnitAPI | @JSR354 | #EclipseUOMo | @AgoravaProj | #DevOps Skype werner.keil | Google+ gplus.to/wernerkeil * JMaghreb 3.0: 6 Nov 2014, Casablanca, Morocco.

More CDI integration on JSF 2.3

by Antonio Goncalves

Hi all, You might have followed Manfred Riem blog, but if not, take a look at what he's doing in JSF 2.3 : integrating even more CDI into his spec : - https://weblogs.java.net/blog/mriem/archive/2014/10/30/jsf-23-changes - https://weblogs.java.net/blog/mriem/archive/2014/10/29/jsf-23-injecting-u... - https://weblogs.java.net/blog/mriem/archive/2014/10/27/jsf-23-allow-cdi-h... - https://weblogs.java.net/blog/mriem/archive/2014/10/23/jsf-23-changes - https://weblogs.java.net/blog/mriem/archive/2014/10/16/jsf-23-changes - https://weblogs.java.net/blog/mriem/archive/2014/10/15/jsf-23-injecting-a... - https://weblogs.java.net/blog/mriem/archive/2014/10/13/jsf-23-inject-exte... - https://weblogs.java.net/blog/mriem/archive/2014/10/10/jsf-23-inject-face... Antoine, any special contact with Manfred ? What having "interviewing" him and write a blog (on the cdi-spec website) about "advantages of having stronger CDI integration" ? That could benefit other spec leads (and therefore, other specs, I'm thinking about Servlet 4 and MVC with Manfred and Ed Burns).

Meeting time slot and daylight saving

by Antoine Sabot-Durand

Hi, As DST is over for most of us, I propose we follow the time shift and keep the meeting time slot at the same time : 6:00 pm CET / 5:00 pm GMT / 9:00 PST Antoine
