Frabjous-Dey Sent: Thursday, October 23, 2008 6:26 PM To: [email protected] Subject: [flexcoders] Cairngorm: should pure view state changes go through the ModelLocator? 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.
