Hey Kevin.
Well my problem was different than yours but I will answer your
question as best I can.
What I would check are:
Make sure your controller is being instantiated on your Main.mxml
page. Like this:
<!-- the FrontController, containing Commands specific to this
appliation -->
<control:MyController id="MyController" />
**NOTE** make sure control: is mapped to the directory you have your
FrontController class in.
If you have the reference to the controller, being instantiated on the
Main.mxml, then move on to the controller itself. Be sure you have a
constructor, and an initialize commands method, that has registered
events, with commands. Using the CairngormEventDispatcher, will fire
your events, but only the FrontController you instantiate will hear
them. At the same time if you are dispatching a CairngormEvent using
the standard EventDispatcher, it will NOT send the event to the
FrontController. This is useful for firing events in a standard way,
for the grid details panel for example, but not when you dont actually
register the Event to a command.
The constructor:
public function MyController()
{
initialiseCommands();
}
The initilseCommands() method:
public function initialiseCommands() : void
{
addCommand( Event1.EVENT_LOGIN, LoginCommand );
addCommand( Event2.EVENT_GET_AUTHENTICATION,
GetAuthenticationCommand );
}
In your commands execute method write a simple popup to test:
execute(){
Alert.show("Testing");
}
Just to see whats happening.
As for your question about the static variables. I dont know that it
makes much difference. I prefer to put mine on the events, simply
because I dont like having a lot of statics attached to my controller,
but it might make sense should you get alot to have them all in one
place. I also do things perhaps a little differently, by creating
general events, such as an AuthenticateEvent, with three Statics, like
LOGIN, LOGOUT, and GETAUTHENTICATED. This way I have one event that
handles multiple functions, but it could get complicated managing it,
should your events require lots of member variables for data payload.
Hope this helps.
