I downloaded the latest code, and it solved the problem I had, but I ran into a
new problem.
I added a single field to MySimpleObject class:
private StatusEnum status = StatusEnum.OPEN;
where StatusEnum is:
public enum StatusEnum {
OPEN,
CLOSE
}
When I attempt to change this field's value like this:
status = StatusEnum.CLOSE; (after MySimpleObject is cached), I get this
exception:
java.lang.RuntimeException: TreeCacheAopDelegate.putObject(). There is existing
pojo under fqn /MyObject/1/status Operation not allowed.

There seems to be a restriction preventing me from changing a cached field. Is
it a temporary restriction (there is a TODO comment in the code). If it's
permanent, is there any work around?
Thanks a lot for all your help!
Just in case, this is the new MySimpleObject.java:
---------------------------------------------------------
package cachetest;
import java.util.ArrayList;
import java.util.List;
public class MySimpleObject {
private String id = null;
private StatusEnum status = StatusEnum.OPEN;
private List decendants = new ArrayList(); // reference to objects of
the same class
public String getId() {
return id;
}
public void setId(String anID) {
id = anID;
}
public MySimpleObject setCrossReferences() {
MySimpleObject retVal = new MySimpleObject();
retVal.setId(getId() + "_copy");
decendants.add(retVal);
status = StatusEnum.CLOSE;
return retVal;
}
}
