Mark Struberg commented on CDI-616:
-----------------------------------
There are cases where it make sense. But actually only with method and ct injection
points.
In the first case we obviously need to store the info about the dependent bean in the
enclosing CreationalContext
{code}
public class MySample {
private MyBean mb;
@Inject
public setMe(MyBean mb) {
this.mb = mb;
}
}
{code}
In the second example it makes perfect sense to mark the injection point as transient:
{code}
public class MySample {
private OtherStuff os;
@Inject
public setMe(@TransientReference MyBean mb) {
this.os = mb.createOtherStuff();
}
}
{code}
Injection point declared as transient is not useful

Key: CDI-616
URL:
https://issues.jboss.org/browse/CDI-616
Project: CDI Specification Issues
Issue Type: Clarification
Components: Concepts
Affects Versions: 1.2.Final
Environment: n/a
Reporter: Emily Jiang
Priority: Minor
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.
=>
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. 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.
Any other better suggestions?
