Assuming that theory is correct, do you have an idea how I should fix it? I've got a band-aid in place, which is to set creationPolicy="none" and then at the end of populating the array, call createComponentsFromDescriptors() on the ViewStack, but there's three problems with that:
1) I'm loading everything at once instead of taking advantage of deferred instantiation to only load what's needed. 2) I'm violating best practices by having my Cairngorm Command class manipulate the view directly. 3) It feels icky. --- In [email protected], "Alex Harui" <[EMAIL PROTECTED]> wrote: > > Oh hey, it might be that the SWFLoader is sized based on its content and > in "all" its content has size of 0.
