Um, that's not accurate.
Bulk actions are only rendered for "standalone" collections of objects, ie
as the result of executing an action that returns a List<Foo>.
The other type of collection we support are "parented" collections, ie that
belong to a single entity.
This can be either explicit eg:
public class Order { public SortedSet<OrderItem> getItems(){ ... } }
or can be a contributed collection:
public class Order { ... }
@DomainService
public class OrderItemContributions { public List<OrderItem> items(Order
order) { ... } }
At any rate, for either type of parented collection does NOT (currently)
support bulk actions.... there are no toggle boxes to select one or several
and apply an object to just those.
~~~
However, parented collections DO allow (regular) actions to be associated
with them, such that these actions appear in the panel above the
collection. This can be done using either the @MemberOrder annotation
[1,2], or done using the .layout.json file for the entity [3].
An example of the latter (recommended) approach can be seen in the example
todoapp, eg [4]
