I faced a situation where multiple instances of the same module are
required to run parallel. Each of my module has a controller of its
own. Now, dispatching a cairngorm event calls the command as many
times as the number of instances of the same module are running. To
get around this pitfall, I am keeping an associative array at the
application level and add the module controller reference to that
array.
I do this in the preinitialize listener of the module:
if (Application.application.controllers["myModule1Controller"] ==
null)
Application.application.controllers["myModule1Controller"] = new
MyModule1Controller();
And then when all the instances of the same module are unloaded, I
remove the reference:
Application.application.controllers["myModule1Controller"] = null;
(Cairngorm ensures that all cairngorm event listeners use
weakReference as true so memory management is automatically taken care
of. Of course, these can also be explicitly removed while unloading.)
so, this ensures that just one instance of the module controller is
present and that too at the app level. This is just a workaround, any
better idea is welcomed.
