I'm attempting to do this with ConvertUtils and BeanUtils.copyProperties:
I have a bag defined in my mapping file and a List defined in my User. I
register the following Customer converter:
public Object convert(Class type, Object value) {
if (log.isDebugEnabled()) {
log.debug("entering 'convert' method");
}
// for a null value, return null
if (value == null) {
return null;
} else if (value instanceof Set && type == Set.class) {
return new ArrayList((Set) value);
} else if (value instanceof List && type == List.class) {
return new ArrayList((List) value);
} else {
throw new ConversionException("Could not convert "+value+" to
ArrayList!");
}
}
When I call BeanUtils.copyProperties(userForm, user), I get the following
error - I'm assuming for a property that is a List of longs.

cirrus.hibernate.collections.Bag implements java.util.List, so you should
be able to copy it into an ArrayList using new ArrayList(bag)...
