I have a class that cannot be cached in hibernate's 2nd level cache using EHCache. It works when i leave out 1 specific property from the mapping. This property is a char(1) mapped to a boolean in java through a custom UserType. However, another property is a enum between 2 chars mapped to a boolean in the same way, and the cache works with this property included.
I should mention that this class works through hibernate as expected with read/write etc, its only the cache that doesnt work.
I have tried upgrading to hibernate 3.2.4.SP1 and the EHCache that comes with it, but this had no effect. I'm using mysql 3.23.58.
Any help is appreciated.

The mapping class of the enum to bool mapping. The char to bool is identical just containing different values for the char.
Code:
public class EnumActivationBooleanStatus implements UserType {
private int[] SQL_TYPES = {Types.VARCHAR};
public int[] sqlTypes() {
return SQL_TYPES;
}
public Class returnedClass() {
return Boolean.class;
}
public boolean equals(Object x, Object y) throws HibernateException {
return x.equals(y);
}
public int hashCode(Object x) throws HibernateException {
return x.hashCode();
}
public Object nullSafeGet(ResultSet rs, String[] names, Object owner) throws HibernateException, SQLException {
if(rs.wasNull()) {
return Boolean.FALSE;
}
String status = rs.getString(names[0]);
return Boolean.valueOf("a".equals(status));
}
public void nullSafeSet(PreparedStatement st, Object value, int index) throws HibernateException, SQLException {
if(value == null) {
st.setNull(index, Types.VARCHAR);
} else {
st.setString(index, (((Boolean)value)?"a":"na"));
}
}
public Object deepCopy(Object value) throws HibernateException {
return value;
}
public boolean isMutable() {
return false;
}
public Serializable disassemble(Object value) throws HibernateException {
return (Serializable) value;
}
public Object assemble(Serializable cached, Object owner) throws HibernateException {
return cached;
}
public Object replace(Object original, Object target, Object owner) throws HibernateException {
return original;
}
}
