I'd suggest to invoke the popup from a view. IMHO, creating a popup or Alert is something only views should be concerned about. Part 4 of my Cairngorm series talks about this: http://weblogs.macromedia.com/auhlmann/archives/2006/09/cairngorm_sampl_3.cfm#more Basically, your command changes a state in the model and a view (MXML) listens to it with i.e. using an Observe tag. The view could then either call the popup API in a Script block or might use a helper class to do that as Dimitrios showed. Best, Alex

Subject: [flexcoders] Re: Cairngorm createPopUp in a command
That reminds me of Jesse Warden's Debugger window he uses in his
Cairngorm examples. I looked at this post just yesterday as we needed
to create a custom alert message window that is shown from the Command
onFault function.
What I did was add a new ArrayCollection object to the Model called
errorAlert. Then in the Main.mxml file I created a ArrayCollection
"collectionChange" event listener that handles any change to the
errorAlert. In each command I add create an error object and add
that object to the errorAlert like model.errorAlert.addItem(myObj).
This fires the collectionChange event and from Main.mxml I pop up my
custom alert component.
There seems to be no real elegant way to throw custom message
components from the Command in Cairngorm, but I like your way
Demitrios, it might be cleaner than listening to changes to the
ArrayCollection object. I did think of one advantage of using my
method, you could create a queue of the alert messages and do clean up
with by firing the "collectionChange" event when you removeItemAt from
the ArrayCollection. This could produce and handle multiple alert
messages layered on top of each other.
