ManagedProperty not injected in @FacesConverter

I'm trying to inject a ManagedBean in my FacesConverted the following way:

@ManagedBean

@RequestScoped

@FacesConverter(forClass = Group.class)

public class GroupConverter implements Converter {



@ManagedProperty("#{groupService}")

private GroupService groupService;



@Override

public Group getAsObject(FacesContext context, UIComponent arg1,

        String groupName) {

    return groupService.findGroupByName(groupName);

}



@Override

public String getAsString(FacesContext arg0, UIComponent arg1, Object group) {

    return ((Group) group).getName();

}



public GroupService getGroupService() {

    return groupService;

}



public void setGroupService(GroupService groupService) {

    this.groupService = groupService;

}



}

The problem is that groupService isn't being injected and I get a NullPointerEx. Shouldn't it be autowired automatically since it's also a ManagedBean? It all works when I change "getAsObject" to "return new Group();" obviously.

Any ideas?

 

The solution:

It is likely that you are not resolving the managed bean name.

@ManagedBean(name = "myConverter")

@RequestScoped

@FacesConverter(value = "myConverter")

public class MyConverter implements Converter {

 

For example, consider these two components:

<h:inputText converter="myConverter" value="#{foo.prop}" />

<h:inputText converter="#{myConverter}" value="#{bar.prop}" />

 

When the converter is set on the first component, it will be created by Application.createConverter. A converter is not a managed bean. The same rules apply if you match a converter by type.

In the second component, a value expression is used to return a class that implements Converter. This uses the usual managed bean mechanisms. In this case, the @FacesConverter annotation is irrelevant.
