Thanks Pedro,
In my AIR app, the user can logout and login, with the available modules
being tied to their profile. If I were to shut the app down on logout,
all my problems would be solvied, because we'd be starting from scratch.
But that seems less than terrific user experience so I'm trying to hit
the holy grail of all modules unloaded on logout, with the app still
running.
Problem is, of course, that when something prevents the module unload,
the app springs a memory leak. I had thought that injecting the model
into the module was the solution, by creating an interface for modules.
This was based upon a presentation by Borre Wessel
(http://blogs.adobe.com/borre/Modularizing_Flex_Cairngorm_and_Modules.pd
f). However, I must not be following his advice in some fashion,
because what I'm doing isn't working. My module's model needs to be
strongly typed in order to set up the necessary bindings between the
model and the components, but the interface to inject the model would be
via interface. The question becomes exactly how do you update the model
when you retrieve data via Delegate? I have tried passing a weak
reference to the module's model in my Caringorm event classes and then
casting it as the strong typed local version the module requires, but no
dice so far.

Hmmm,
If you are using Cairngorm + Modules take a look at Modular
http://lab.arc90.com/2007/10/modular_1.php
This problem is not the only one that you will face when working
with Cairngorm + Modules, trust me
HTH,

I've done a bit more research. At this point it doesn't
appear to be the renderers - I took them out for testing and it looks
like that the way I'm injecting model objects into Module that might be
at fault. Right now, I've defined a model interface that I'm passing
back to the Commands inside of the Cairngorm events. I'm kind of
hacking my way through this.
Driving me crazy, though. Shouldn't be rocket science
to unload a freakin' module.

Hi Jeff,
Do your renderers have some reference to module
data?
How are your grid and your module related?
I think we need more info to help you.

I'm using the profiler to get handle on
what's causing a given module to
fail to unload and it appears that the
datagrid is the culprit.
Specifically when the data grid is
unpopulated, I can successfully
unload the module. When it is populated,
it won't. I have the datagrid
bound to a local model object. It
appears that as soon as the datagrid
has children, the module won't unload
completely.
There must be some reference that the
datagrid has that is causing this
- I am using some custom item
renderers/editors. Any advice greatly
appreciated.
