Simple Question about execute()

[Matt Abrams]

James -

Your iterator is on the "added" collection.  An subscription will  
invoke the execute method of your plugin when the objects that match  
your predicate are added, changed, or removed.  If you'd like to  
process changed objects as well as added objects then you should have  
another snippet of code like:

> for (Iterator i = HypothesisSub.getChangedCollection().iterator();  
> i.hasNext();) {
