bulk updates

[Stephen Cameron]

Hi,

I am trying to copy the 'bulk' action example in the kitchen sink app, but
I don't see the check boxes on the left hand column in my collection. What
can I be missing?

I am assuming that the annotation as follows is what gives the magic!

@Action(invokeOn = InvokeOn.OBJECT_AND_COLLECTION)

but maybe not alone?

My Attended class is as follows.

package au.com.scds.chats.dom.module.attendance;
