I'm assuming you can't change them because someone else created them? There
are still ways you can deal with the beans with sets..
1) Wrap them using the Adapter pattern. However if they are already coming
back nested and you can used the adapters/wrappers in the business layer you
could also..
2) Push them through a conversion utility in the service layer that adds
them to your wrappers/adapters and then use those objects with Lists...
ActivityWrapper {
EoActivity eoActivity;
getName() { return eoActivity.getName() }
List getUsers() { return new ArrayList( eoActivity.getUsersSet() }
List setUsers(List list) { Set set = new Set();
set.addAll( list );
eoActivity.setUsersSet( set );
}
ActivityUser
//same thing like above
Unfortunately you're also going to want to use Session scope for the Action
form that holds your "List activittyWrappers" property. You can do it
without using Session scope, but you then add some extra complexity based
off some limitations in Struts1.1. If Request scope is a must, it can be
done though.
