You don't need it if the <value> is dynamic already (you're using EL in it). JSF will take care of it. Just omit the <property-class>. You only need it if the <value> is static and you want to set it as something else than String (which it defaults to).

Unrelated to the concrete problem, since JSF 2.0 you don't need the stinkin' faces-config anymore to declare managed beans and managed properties. You can use annotations.

@ManagedBean(name="MyBean")
@RequestScoped
public class MyBean {

    @ManagedProperty(value="#{FMTools.selectedEnvironment}")
    private List<String> selectedEnvironment;

    // ...
}
