[cdi-dev] [JBoss JIRA] (CDI-616) Injection point declared as transient is not useful

[Emily Jiang (JIRA)]

    [ https://issues.jboss.org/browse/CDI-616?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13310128#comment-13310128 ] 

Emily Jiang commented on CDI-616:
---------------------------------

On f2f, the suggestion is to add "Injection in transient field is not supported. Non portable behaviour will occur" under 5.2.5.

After some more thinking, I still think what I proposed originally is better, which is to add the following sentences under 5.5.7.  
"
If this injection point is declared as transient, after bean's passivation, the value will not be restored. Instance<> injection point is the preferred approach.
"
Thoughts?

> An injection point declared as 'transient' is not useful, due to the fact of after bean's passivation, the transient field will not be reinjected and its value will be lost. This causes confusion. See Weld forum discussion [link title|https://developer.jboss.org/thread/179486]. In the section 5.5.7, how about to make the following changes?
> The isTransient() method returns true if the injection point is a transient field, and
> false otherwise. If the injection point represents a dynamically obtained instance then the
> isTransient() method returns true if the Instance injection point is a transient field, and
> false otherwise.
