[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-3998) Injection of SortedMap throws IllegalArgumentException

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:

problem. So I suspect that somewhere a SortedMap is being initialized with a HashMap.
