Problem with JSF2 + CDI + Tomcat

Question

Personal talk,
I’m working with JSF and I’m here. I have a simple project for now, with a page with a form that has an Enum attribute in it, IE, when the page is loaded has a selectItems there that should be loaded from Enum.
Using @Managedbean and the JSF scope it works normally. But when I try to migrate to CDI, Enum ceases to be loaded. I have tested trying to write a simple attribute on the screen and neither will. From what I saw, it should be simple, but I’ve followed several tutorials and failed miserably. Of course it must be silly of me, but I can’t see what it is. In the console no error msg appears and the page loads normally, only it does not bring anything from Managed Bean. I already wrote down named in bean, Enum and nothing. And then, what’s the catch?

You are only using the cdi api. You need the implementation as well, since Tomcat does not implement cdi.

<dependency>
    <groupId>org.jboss.weld.servlet</groupId>
    <artifactId>weld-servlet</artifactId>
    <version>2.4.8.Final</version>
</dependency>
