> If I have a managed bean which extends a generic bean, than property injection from faces-config.xml doesn't sign error if I inject property with incompatible type.
> Eg.:
> public class MyGeneric<MYTYPE extends Serializable> {
>     protected MYTYPE myProp;
>     public void setMyProp(MYTYPE val) {
>         this.myProp = val;
>     }
>     ....
> }
> public class MyBean extends MyGeneric<Long> {
>     ....
> }
>     <managed-bean>
>         <managed-bean-name>myBean</managed-bean-name>
>         <managed-bean-class>MyBean</managed-bean-class>
>         <managed-bean-scope>request</managed-bean-scope>
>         <managed-property>
>             <property-name>myProp</property-name>
>             <value>#{param.myPropVal}</value>
>         </managed-property>
>     </managed-bean>
> This example will inject the myPropVal request parameter (which is a String) into the myProp property of MyBean class which is a Long, and it won't throw ClassCastException. But later if I check the type of the property value it will be String - and probably it will fail my code somewhere else.
> If MyBean doesn't extend from a generic class, but has its own, Long typed property, than I will have the ClassCastException during the injection.
