RE: [flexcoders] Accessing methods in nested components

[Gordon Smith]

If you cast parentDocument to your application class, the compiler can tell you whether you've constructed the right _expression_ or not. For example, if your app is MyApp.mxml, then do       MyApp(parentDocument).filenet...   Without the cast, it can't typecheck anything because parentDocument is a generic Object on which you can access anything dynamically, including things that don't exist.   - Gordon   From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Pascal Schrafl Sent: Monday, October 23, 2006 4:26 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Accessing methods in nested components   Hi all, I'm new to Flex but used OpenLaszlo before. I must now build an application to use with Zinc for my studies and as OpenLaszlo is not supported by Zinc, I decided to use Flex 2. I have several components and would like to call some methods in other components. Here's my application structure: main Application <component: login> which is a panel <component: filenet> which is a canvas within the filenet component I have several different components: <component: sidebar> which is a accordion. within the sidebar, there is a component called: <component: addressBookTab> which is a canvas and in this component there is an other component called: <component: addressBook> which is a canvas in the addressBook component, I want to call a HTTPService, but I must call it, after the user has authenticated himself (using the login component). I use the getAddressBookEntries() Function to call the HTTPService. I therefore have a function, that handles the login. If the server gives back a true, then I would like to call the HTTPService and load the user specific data. I use the following command: parentDocument.filenet.sidebar.addressbookTab.addressBook.getAddressBookEntries(); I use the parentDocument property to get out of the login component and then try to go all the way down to the addressBook component and call the appropriate function. Unfortunately, I don't have any success, as the method doesn't get called. Am I doing something wrong? There must be some way to call a method from a component within an other component. Perhaps I use to many components, and this causes the error? I have ensured, that all id's assigned are unique within the whole application. I hope you can help me solve this problem. If it is useful to post the source code, just let me know. Thanks a lot for your help.
