Injection of SortedMap throws IllegalArgumentException
------------------------------------------------------
Key: JBSEAM-3998
URL: https://jira.jboss.org/jira/browse/JBSEAM-3998
Project: Seam
Issue Type: Bug
Components: Core
Affects Versions: 2.1.0.SP1
Reporter: Naresh Bhatia
I have a bean called instrumentManager that contains a factory to create a SortedMap of
Instruments:
@Name("instrumentManager")
@Scope(ScopeType.CONVERSATION)
public class InstrumentManager implements Serializable {
@In private InstrumentRepository instrumentRepository;
@Out(required=false)
private SortedMap<String, Instrument> instrumentMap;
public SortedMap<String, Instrument> getInstrumentMap() {
return instrumentMap;
}
@Factory("instrumentMap")
public void createInstrumentMap() {
List<Instrument> instrumentList = instrumentRepository.findAll();
instrumentMap = new TreeMap<String, Instrument>();
for (Instrument instrument : instrumentList) {
instrumentMap.put(instrument.getSymbol(), instrument);
}
}
}
I am injecting the instrument map in a JSF converter bean:
@Name("instrumentConverter")
@Converter(forClass=Instrument.class)
public class InstrumentConverter implements javax.faces.convert.Converter {
@In(create=true)
private SortedMap<String, Instrument> instrumentMap;
@Override
public Object getAsObject(
FacesContext context, UIComponent component, String value) {
if (StringUtils.isEmpty(value)) {
return null;
}
return instrumentMap.get(value);
}
@Override
public String getAsString(
FacesContext context, UIComponent component, Object value) {
return value.toString();
}
}
When the converter tries to access the instrument map, I get the following exception:
14:22:30.484 WARN [javax.enterprise.resource.webcontainer.jsf.lifecycle] could not set
field value: instrumentConverter.instrumentMap
java.lang.IllegalArgumentException: could not set field value:

Note that replacing the SortedMap everywhere with just a java.util.Map fixes the problem.
So I suspect that somewhere a SortedMap is being initialized with a HashMap.
