New beans on weblogic not found

Question

I have an Java web application, running on weblogic, with 100 or so existing beans setup with annotations in the form:

import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;

@ViewScoped
@ManagedBean(name = "[beanName]")
public class BeanPage

Suddenly when I add new beans I get the following error when referencing them from the xhtml:

javax.faces.FacesException: #{[beanName.init]}: javax.el.PropertyNotFoundException: [url.xhtml] @10,53 action="#{beanName.init}": Target Unreachable, identifier 'beanName' resolved to null

All the existing beans work fine, but I consistently get this error with new beans. Even if it's a copy of an existing working bean. I do not get this error running on Tomcat, the new beans work well.

I have seen the item on setting up beans and tackling different error messages, but I don't think it addresses my problem when everything appears setup correctly it's just new beans running into issues: Identifying and solving javax.el.PropertyNotFoundException: Target Unreachable

I have tried Maven clean, update, deleting the project and checking it out fresh, deleting the server and recreating it.
