bean discovery mode

Flow
1

Hi everyone,
i was doing the cdi-vaadin tutorial and i think there are serveral issues very important that the tutorial doesn’t mention.
I use wildfly as server.

1 - The file beans.xml is mandatory if you intend to use cdi.
2 - You must use bean discovery mode “all” and not “annotated” in the bean.xml file

If you use annotated the server:

  • Doesn’t recognize the vaadin-cdi beans (@UIScoped, …)
  • You must write @Dependent (this is the default scope in CDI specification).

Thanks for the important suggestions. Let’s see if I can get someone to update that tutorial. It seems to need some revising anyways. And just to make sure? You mean this tutorial:

Yes this is the tutorial.
Well, the tutorial use another server TomEE ( wildfly needs beans.xml (even if it is empty) ).
The discovery mode is a little bizarre but explain differents behaviour of scanning the beans cdi.
I’m a begginner, i just only get an explanaition (but i supposed this questions are to Wildfy Forum in JBoss web).

It 's normal the out of date in a tutorial with it is made two years ago (it is mentioned in the tutoria).
PD:
English is not my maternal language so it is weird for me when you said… it seems to need some love???

I edited my answer to make the language less metaphorical.
