Indexed Properties with Sets

[Matt Raible <ma...@raibledesigns.com>]

I've had much success doing indexed properties with a java.util.List, 
but no luck with figuring out how to do it with a java.util.Set.  Is it 
possible?  With a list, you can use the setProperty(index i, ActionForm 
form) signature, but I haven't been able to figure out how to do this 
with a Set.  Is anyone doing this?

As an alternative, I suppose I could modify my Form -> POJO conversion 
to detect Sets and properly convert List to Set.

Thanks,

Matt

Unfortunately I think this is what you are going to have to do Matt. I'd 
  keep the Set property in the form bean, but use the List property in 
the html:

//ActionForm

Set someSet;
List someList;

getSomeList {
    //*gets someList from the someSet
}

setSomeList
    //sets someList
    //*also populates someSet from someList

setSomeSet
    //sets someSet

getSomeSet
    //gets someSet

Now the above should work even if your Value Object has a Set property.
