I agree with Martin. We *should* fix this situation in the long term, which is what I proposed. However in the short term there is no problem with not passing a particular test from the EL spec. Additionally this is provably implementable as Weld implements this, and many Java EE containers pass. As there are no other spec defined beans javax, then we do not conflict with any other spec by implementing it this way. > > >On 14 Jan 2015, at 12:10, Martin Kouba <mkouba(a)redhat.com&gt; wrote: > >Dne 14.1.2015 v 12:43 Romain Manni-Bucau napsal(a): > >well there are 2 points: >>1) a test should be added for it >> >There was a CDI TCK test since 1.1 (org.jboss.cdi.tck.tests.context.conversation.LongRunningConversationPropagatedByFacesContextTest).

An EL TCK test can't evaluate "#{javax.enterprise.context.conversation.id}" as an illegal expression - it's obviously legal. The problem is "javax.enterprise.context.conversation.id" can't be simply used as a bean name. If it is, a workaround is needed (see also http://lists.jboss.org/pipermail/cdi-dev/2015-January/005989.html). > > > >> >>Romain Manni-Bucau >>@rmannibucau >>http://www.tomitribe.com >>http://rmannibucau.wordpress.com >>https://github.com/rmannibucau >> >> >>2015-01-14 12:35 GMT+01:00 Pete Muir <pmuir(a)redhat.com&gt;: >> >>Which EL test? >>> >>> >>>On 14 Jan 2015, at 11:30, Romain Manni-Bucau <rmannibucau(a)gmail.com&gt; wrote: >>>> >>>>then it will not pass EL one >>>> >>>> >>>>Romain Manni-Bucau >>>>@rmannibucau >>>>http://www.tomitribe.com >>>>http://rmannibucau.wordpress.com >>>>https://github.com/rmannibucau >>>> >>>> >>>>2015-01-14 12:27 GMT+01:00 Pete Muir <pmuir(a)redhat.com&gt;: >>>> >>>>No, a Java EE container needs to pass this test. >>>>> >>>>> >>>>>On 14 Jan 2015, at 11:21, Romain Manni-Bucau <rmannibucau(a)gmail.com&gt; wrote: >>>>>> >>>>>>so it means a JavaEE container will not pass this test but it is not an issue? >>>>>> >>>>>> >>>>>>Romain Manni-Bucau >>>>>>@rmannibucau >>>>>>http://www.tomitribe.com >>>>>>http://rmannibucau.wordpress.com >>>>>>https://github.com/rmannibucau >>>>>> >>>>>> >>>>>>2015-01-14 12:20 GMT+01:00 Pete Muir <pmuir(a)redhat.com&gt;: >>>>>> >>>>>>I don’t think they should be excluded.

This means CDI 3. So I would suggest we deprecate it in 2, add an alternative that can be used, and then consider removing it in CDI 3. In the meantime for CDI 2, we will need to improve the TCK to check this more carefully. >>>>>>>>> >>>>>>>>> >>>>>>>>>On 14 Jan 2015, at 10:09, Romain Manni-Bucau <rmannibucau(a)gmail.com&gt; wrote: >>>>>>>>>> >>>>>>>>>>+1 for B (IMO it is not used that much) >>>>>>>>>> >>>>>>>>>> >>>>>>>>>> >>>>>>>>>> >>>>>>>>>>Romain Manni-Bucau >>>>>>>>>>@rmannibucau >>>>>>>>>>http://www.tomitribe.com >>>>>>>>>>http://rmannibucau.wordpress.com >>>>>>>>>>https://github.com/rmannibucau >>>>>>>>>> >>>>>>>>>> >>>>>>>>>>2015-01-14 10:54 GMT+01:00 Jozef Hartinger <jharting(a)redhat.com&gt;: >>>>>>>>>> >>>>>>>>>>I think further action is needed on this.
