[cdi-dev] [JBoss JIRA] (CDI-590) Provide a way to produce any type in a producer

[Romain Manni-Bucau (JIRA)]

    [ https://issues.jboss.org/browse/CDI-590?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13180593#comment-13180593 ] 

Romain Manni-Bucau commented on CDI-590:
----------------------------------------

[~mkouba] deltaspike example is not really relevant there cause it doesn't support a lot of types. Just use PropertyEditor API and deltaspike producers wouldn't work anymore and that's just a trivial case. If you use tamaya, Tamaya has its own coercing system which wouldnt fit CDI very well without that feature IMO.

> Note: this is a follow up "adding generic producers to CDI 2.0?" thread on the list
> It is common to rely on a subsystem (another IoC, a coercing system, ...) to produce values. Today a producer can't say "I produce anything in a safe" manner.
> Idea would be for injection point aware producers with a qualifier to producer Object and match all types.
> It needs another flag (can be in @Qualifier or another annotation it is not really important) to say "I produce safely any type".
> I did a PoC on github: https://github.com/rmannibucau/generic-producer-cdi but think it can be a nice feature of CDI 2.0 since it would avoid users to have to dig into extensions for several simple cases (configuration, bridge to other IoC...)
