Yes, all normal scopes that are available in standard Java EE support
this as far as I know.

There's the small caveat that CDI itself doesn't know about this
automatically for any custom normal scope. That implementation of such
scope (via a Context) must explicitly throw these events.

For example, this is what Mojarra does for the @FlowScoped implementation:


Which is fired when the scope starts here:

(the exact same code is used for @ViewScoped in Mojarra as well)

Yes, that is what this does ;)

Kind regards,
