Ertio Lew created MYFACES-3599:
----------------------------------
Summary: Using Collections.EMPTY_LIST inside converter leads to
IllegalAccessException
Key: MYFACES-3599
URL: https://issues.apache.org/jira/browse/MYFACES-3599
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 2.1.8
Environment: Glassfish 3.1 & JUEL EL Implementation
Reporter: Ertio Lew
While using a string->list(& viceversa) converter, I made use of
Collections.EMPTY_LIST but it gives the following error. (This worked fine with
Mojarra)
<error>
<error-name>java.lang.IllegalStateException</error-name>
<error-message>java.lang.RuntimeException: java.lang.IllegalAccessException:
Class javax.faces.component.UIComponentBase can not access a member of class
java.util.Collections$EmptyList with modifiers "private"</error-message>
</error>
Why cannot I use Collections.EMPTY_LIST but new ArrayList<Integer>() just
works ?
Converter code as follows:
------------------
FacesConverter(value = "listConverter", forClass =
px10.Utils.ListConverter.class)
public class ListConverter implements Converter {
@Override
public Object getAsObject(FacesContext fc, UIComponent uic, String
stringVal) {
if (stringVal==null)
return Collections.EMPTY_LIST;
String[] split = stringVal.split(",");
List<Integer> list = new ArrayList<Integer>(split.length);
for (int i = 0; i < split.length; i++) {
list.add(Integer.parseInt(split[i]));
}
return list;
}
...
...
}
