Hi Ezequiel,
I'm cc'ing dev on this reply, since some of the committers might want to

yes, the request makes sense, but unfortunately right now there's way to
get this information.
Arguably the "right" thing to do would be for bulk actions to be
implemented as an action on a domain service that takes a list of object.
However, making this change would be a big deal, and isn't one that I want
to embark at the moment.
What would be easy (though I'm not sure if it's reasonable or not) would be
to define a ThreadLocal in the applib, and use this as a means to pass
context information.
I've just spiked this, it works well enough:
@Bulk
public ToDoItem completed() {
...
final BulkInteractionContext ctxt = Bulk.interactionContext.get();
@SuppressWarnings("unused")
List<Object> allObjects = ctxt.getDomainObjects();
LOG.debug("completed: "
+ ctxt.getIndex() +
" [" + ctxt.getSize() + "]"
+ (ctxt.isFirst() ? " (first)" : "")
+ (ctxt.isLast() ? " (last)" : ""));
...
}
when I run this with 3 todo items selected, my log prints out:
20:36:30,351 [ToDoItem 2091197094@qtp-722659319-1 DEBUG]
completed: 0 [3] (first)
20:36:30,371 [ToDoItem 2091197094@qtp-722659319-1 DEBUG]
completed: 1 [3]
20:36:30,373 [ToDoItem 2091197094@qtp-722659319-1 DEBUG]
completed: 2 [3] (last)
The idea, then, is that you could write the action to be a no-op except for
when called for the first (or last) time, in which case it could work on
all the objects provided via ctxt.getDomainObjects().
~~~
I'm not sure if using a ThreadLocal in this way is just too hacky for
words... but if no-one objects, I'll check it in anyway....
