[cdi-dev] Answer from EL spec lead: no, "." is not valid in an EL name.

Wed Jan 14 07:12:57 EST 2015

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.

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 <http://lists.jboss.org/pipermail/cdi-dev/2015-January/005989.html>).

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.
