Performing bulk operations on view models

[Vishma Senadhi Dias <vi...@cse.mrt.ac.lk>]

Hi all,

I have a JAXB annotated view model consisting several collections. ( 
several other view models ; like in the todo-app dashboard). Is it 
possible to use ActionInvocationContext and invokeOn to select multiple 
instances of a collection and do a bulk operation where there is more 
than one collection?  I can do this bulk operation inside of the 
collection. But what I need to do is to enable bulk operations right at 
the dashboard page.

Example :

Public class Cat { ... }

Public class Dog { ... }

Public class Animals {

            List<Cat> cats;
            List<Dog> dogs;
}

Animals page acts as a dashboard in this context. I need to perform bulk 
operations on either collection by selecting from the collection tables 
on the animal screen. Is this possible?
Hope you can understand my question.

Best Regards,
Vishma.

Thank you Dan. I used the tip of yours and it works fine for now.

I hope that you will include this functionality on future builds, as 
even it seems like a small issue, when it comes to the UX point of view 
it could be critical in certain applications.

Cheers,
Vishma.

Hi Vishma,

yes, the question makes sense, but this capability isn't there yet.  I
think that there's a ticket requesting it, but it hasn't got to the top of
the pile.

The workaround is to have your view model provide an action that returns a
standalone collection against which you can perform the bulk actions.
