how to add a reference to two field of one object
Address a = new Address();
a.setAddr1("aaaaaaa");
a.setAddr2("bbbbbbbbbbbb");
cache_.attach("address/1", a);
Address b = new Address();
b.setAddr1("aaaaaaa");
b.setAddr2("bbbbbbbbbbbb");
cache_.attach("address/2", b);
PersonWithDoubleAddress pwda = new PersonWithDoubleAddress();
cache.attach("pwda", pwda);
pwda.setAddress1(a);
pwda.setAddress2(a);
This is a snap .
when run to black .an error appear:
