Use a debug build so you get line numbers and post the entire stacktrace if it isn't clear where the problem is.

What I am having trouble with is reproducing it in my flex development environment. I have an application that calls custom components into a ViewStack. When the user changes sections within the viewstack it fires an event which calls a public method called saveSection within the custom component - the section they just left. When debugged and run within my Flex dev environment it works fine, until I deploy it to another development machine. It's then that I get the Error 1009. This is driving me crazy. This code has previously worked fine. I'm happy to post some pseudo code or examples if needed, but generally I'm after advice. If I am viewing the component called into the viewstack... how can it be null? Complicating this is that the same code called for the other sections works as expected! The creationPolicy on the viewstack is "all" MainApp {changeSectionHandler -> oldSection.saveSection()} ViewStack SectionA {saveSection()} SectionB {saveSection()} SectionC {saveSection()} Any help appreciated. Cheers Steve
