That's a good rule !

If your 2 components in your view are in the same component, let's say  
whatever Panel or Canvas you can think of , I don't see why you should  
go all the MVC way.

I also vote for #2. Seems strange for me to have a boolean in the
ModelLocator that is specific to this UI context. I always thought the
ModelLocator should only have data that is potentially global to the app
(like your list of users), and find it strange that many online Cairngorm
examples put something like the working item of an edit form (e.g., you have
a form that edits the properties of a specific user, and a variable for that
user is added to the ModelLocator). So I wouldn't consider your boolean
flags to be part of your app's model.

  Hi everyone,

 Here's a design question for you Cairngorm experts.

 In my application's view, I have two main subcomponents: a control bar sort
 of custom component that I wrote that we'll call the FrabjousControlBar, and
 a DataGrid, which lists all the users in my application.  These users are
 either Administrators or Members.

 The FrabjousControlBar contains two checkboxes: a checkbox labeled Show
 Administrators and a checkbox labeled Show Members.  Both are checked by
 default, but when Show Administrators is unchecked, the DataGrid removes
 all of the Administrators.  Something similar happens for Show Members.

 I'm having trouble choosing the correct implementation for this.  There are
 two ways I can see to do this:

 1) When a user unchecks Show Administrators, the control kicks off a
 Cairngorm Event, the controller executes a Command that changes a boolean
 flag in the ModelLocator, and the DataGrid responds to the change on that
 flag.

 2) Since the user interaction affects the view only, no MVC round trip
 occurs.  My view knows when the box is unchecked and updates the DataGrid
 accordingly.

 Which is better?  1) is more pleasingly MVC, but comes with a lot of
 overhead and additional effort.

 Thanks,
 O.
