[cdi-dev] Question regarding producer methods and default no-arg constructor

[Michael Remijan]

Yes that's right.  I don't want the bean activated directly because the producer method does some additional logic before activation.

 Hi Michael,

1) yes if the bean is scanned as well
2) you can use @Alternative but using <scan />, @Vetoed, or @Typed()
for CDI 1.0 should work as well and are maybe less hacky since you'll
never activate this alternative right?
