problems with @Injection

Question

Hi, guys. I’m creating a program that manipulates human and livestock records. In this program, on the livestock register screen, I am creating two Selectonemenu of the first faces. One is of type of cattle and the other of breed of cattle. These two Selectonemenus are dependent. That is, for example, if the user selects "bovine" in the type, in the breed the bovine breeds must appear to be chosen.

After I started implementing the Selectonemenu (to be more precise, when I implemented the cattle type), a build error started to appear WELD-001456: Argument resolvedBean must not be null.

I searched the internet and several articles talked to change the version of Weld, but I tried and the error persists. The current version I am using in the project is 2.3.5 Final. I tried changing this version in pom.xml and updating the Maven project, but the error persists.

This error appears when I try to load the cattle registration page. One thing I find strange is that there are times that in the Eclipse console appears the error of WELD-001456 and there are times that the error appears Cannot find Component for Expression "typed" referenced from "j_idt33:type"..

In addition, in the console sometimes appears in black letter, a message warning that it was not possible to perform the inject, but this message also does not appear every time.

I’m sending you the code of the files I believe are related to.
