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

Mark, although the transient dependent scoped bean injection point can be worked around, it is not as easy and simple as using @Inject Instance<>.

> 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?
