Matthias Miraculix commented on JBSEAM-1326:
--------------------------------------------

Made my own EnumConverter-Impl. which does not rely on getExpectedType ... 
Don't know which drawback's this method has: 


<code>
public class EnumConverter implements Converter, StateHolder
{
	public static final String CONVERTER_ID = "com.my.common.jsf.converter.EnumConverter";
	private boolean istransient;
	private Class type;
	
	@SuppressWarnings("unchecked")
	public Object getAsObject(FacesContext context, UIComponent comp, String value) throws ConverterException {
		return Enum.valueOf(type, value);
	}

	public String getAsString(FacesContext context, UIComponent component, Object object) throws ConverterException {
		if (object == null) {
			return null;
		}
		this.type = ((Enum) object).getClass();
		return ((Enum) object).name();
	}

	public void restoreState(FacesContext arg0, Object state) {
		Object values[] = (Object[]) state;
		this.istransient = (Boolean) values[0];
		this.type = (Class<? extends Enum>) values [1];
	}

	public Object saveState(FacesContext arg0) {
		Object values[] = new Object[2];
		  values[0] = istransient;
		  values[1] = type;
		  return (values);
	}

	public void setTransient(boolean istransient) {
		this.istransient = istransient;
	}
	
	public boolean isTransient() {
		return istransient;
	}
}

> Did a build of seam-cvs recently and it breaks s:enumItem functionality in my webapp as well as the seam-pay example.  Brief exception here:
> Caused by: java.lang.IllegalArgumentException: java.lang.Object is not an enum type
>         at java.lang.Class.enumConstantDirectory(Class.java:2965)
>         at java.lang.Enum.valueOf(Enum.java:187)
>         at org.jboss.seam.ui.EnumConverter.getAsObject(EnumConverter.java:17)
