Command getting fired twice in module with cairngorm

[gurpreet]

I am loading modules in my application which is based on Cairngorm.
Each of the module has its own frontcontroller. I'm facing an issue
that when a cairngorm event is dispatched within the module, the
command execute() method gets called twice. Has anyone faced this
before?

Really need some help here...

Thanks in advance
gurpreet

Mapping the events to command is a kind of event listener only.
So, if even if the view goes out of the application, it doesn't mean the handlers attached will also go away. There are possibilities that they will respond even if the view have been removed from the list.
Use the weak-reference true, while adding the command in the controller and use removeCommand() while you unload the module. Also, keep the event names unique across all modules.

Is your problem fixed? It's a bit tricky to get Modules and
Cairngorm work together. Is your main application also using
Caringorm?

Thanks guys for all the inputs.

I was able to fix the issue. What was happening is that on unloading
the module, I was not removing the listed commands for that
controller. On loading the module again, each command would get added
again. So if I unload and load the module 5 times, the command would
get added 5 times.

Now I've added the following function to the module controller and
call it every time the module unloads. This cleans up the commands
list from the controller.

public function removeAllCommands():void
{
for (var key:String in commands)
{
removeCommand(key);

Hi,

I encountered this issue too. But I'm not able to fix it. Could you tell me where did you put removeAllCommands() ? Thanks a lot.
