managed-property injection fail type cast on managed beans which extends
generics
---------------------------------------------------------------------------------
Key: RF-7193
URL: https://jira.jboss.org/jira/browse/RF-7193
Project: RichFaces
Issue Type: Bug
Components: core
Affects Versions: 3.3.0
Environment: Win XP, Tomcat 6.0, JDK 5, Richfaces 3.3.0 GA
Reporter: Zoltan Kiss
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.
