Duplicate objects for gallery

Question

I have tried a couple of times to duplicate objects, in
different ways, so I can later put image into the objects. The
problem is that it works in Flash but when i try it out in my
browser or my friends browser it wount work at all.
So if there is one out there that can explain this or can
point me into right directions it would be alot of help.
Kind Regards
Mario

Hi Michael,
Not really, as Coherence only compares keys for equality, not the values, when deciding where to store the objects.
What you could do however, is something along the lines of what I described in the previous post -- you could introduce an intermediary pointer/reference object that would only contain an id of your true value object:
public class MyObjectReference implements Serializable {
private static final NamedCache myObjectCache = CacheFactory.getCache("myObjectCache");
private Object id;
public MyObjectReference(Object id) {
this.id = id;
public Object getId() {
return id;
public MyObject getValue() {
return myObjectCache.get(id);
Then your code would become similar to this:
NamedCache myRefCache = CacheFactory.getCache("myReferenceCache");
NamedCache myObjectCache = CacheFactory.getCache("myObjectCache");
MyObject myObj = ...
myObjectCache.put(myObjId, myObj);
myRefCache.put(1, new MyObjectReference(myObjId));
myRefCache.put(2, new MyObjectReference(myObjId));
myRefCache.put(3, new MyObjectReference(myObjId));
Assuming your object is much bigger than its key/identifier, this approach could save you a lot of space in the cluster, as each reference object is very small, while still allowing you to access your value object using different keys and dereferencing:
MyObject myObj = ((MyObjectReference) myRefCache.get(1)).getValue();
You could replace key 1 with 2 or 3 above and the result would be the same.
