[flexcoders] Loading AVM1 content into AVM2
Hi guys, I've hit a huge hurdle when trying to communicate between AVM1 and AVM2. I've been trying to create a component - call it AVM1Loader - which will allow simple communication between an AVM2 flex app and a contained AVM1 file. In theory, it's pretty simple: - Use Loader to load the file. - Create a LocalConnection for AVM2 to talk to AVM1 - Create a LocalConnection for AVM1 to talk to AVM2 This all works fine, and communications all work. However, the problem comes with the naming of the LocalConnections. Clearly each AVM1Loader instance wants to have a differently named pair of LocalConnections; otherwise you'll get into trouble if you're trying to have two AVM1Loaders running together at the same time - or even two instances of the same Flex app running together at the same time. Generating a unique ID is easy, but I can't for the life of me work out how to communicate it to the contained AVM1 file. The obvious way would be to pass it as a parameter: e.g. _loader.load(new URLRequest(AVM1File.swf?key=+someUniqueKey)); That works, but only (apparently) once. The next time you try to load AVM1File.swf with a _different_ key (under a whole new instance of AVM1Loader) something very odd happens. The key value does get transmitted correctly on the second run, but the _root of the contained movie gets screwed up. These simple trace statements are on the root of AVM1File.swf: trace(_root); trace(_root.clip); // (Clip is an instance defined on the stage of AVM1File) trace(_parent); On the first (successful) load (i.e. loading AVM1File.swf?key=someUniqueKey), I get: _root _root.clip undefined Which is as expected. On the second run through (i.e. loading AVM1File.swf?key=someOtherKey), I get: _root _level0.App0.Panel4.contentPane.AVM1Loader40.instance55.instance56.clip _level0.App0.Panel4.contentPane.AVM1Loader40.instance55 Which is very strange - suddenly my AVM1 code is seeing its AVM2 instance name. And from that point on, the AVM1 code stops working correctly - loading clips etc. fails. If I change the URL to just AVM1File.swf it all works fine, but obviously my unique key doesn't get transmitted. Similarly, fixing the URL - sending AVM1File.swf?key=dummy each time - works fine. Somethings up when you alter the parameter. It's a new instance of Loader() - I'm not reusing anything. So - that's clearly some sort of bug, and I seem to have hit a blank wall there. If anyone's got any ideas on that peculiarity then great. But that aside, if anyone's got any brainwaves on how to simply communicate a unique ID to an AVM1 file I'm loading, that'd be great. :-) Yours in frustration, Ian -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

Re: [flexcoders] Loading AVM1 content into AVM2
That most definitely sounds like a bug ... I think the following would work: - Create a class LocalConnectionDaemon in AVM2 that is connected under a hardcoded LC name. ( e.g. LC_DAEMON ); - Create a class LocalConnectionDaemon in AVM1 that does the following: - Generates a unique LocalConnection URL based on the current-time-millis ( e.g. var clientId:String = LC_CLIENT_1324343243243 ) - Send a command to LocalConnectionDaemon via - LC_SERVER .. createClient( clientId ) - Listen for a command (on that same LocalConnection, or one the server can figure out) called onClientCreated( otherClientId:String ) - LocalConnectionDaemon should have a method createClient( clientId:String ) that takes the ID, and transforms it to a guaranteed unique name (e.g. var newClientId:String = clientId + _AVM2) and sends onClientCreated( newClientId ); Definitely more painful, but doable. I should point out that one big issue with LocalConnection is that messages are limited to 40kb. You may need to chunk your requests over if they are large. Also, just thought this would be a good time to point out Adobe's bug-report / wishlist page.

Re: [flexcoders] Loading AVM1 content into AVM2
Hi Daniel, Thanks for that. If I understand you correctly, you're suggesting creating a known LocalConnection which acts as an 'ID server' in AVM2. I had thought about something similar. The issue is that I can't see how the pairing up works between an AVM1Loader (the AS3 component) and it's contained AVM1 movie. I can understand using a known point for the AVM1 movie to talk to, but can't see how you can guarantee that the right IDs can be guaranteed to be known by both parent and child if, for example, two such pairs are being created at the same time. You can't queue it - e.g. FIFO - because you can't guarantee that the first AVM1 movie loads faster than the second. And you can't even do it by URL mangling or somesuch, because we might be dealing with loading the same movie into two different components (which is the case in my setup). Additionally, I think the known server fails if (for example) two copies of the same Flex app were running at the same time - although I guess you could get around that by querying LC_DAEMON to see if it already exists before creating it. I'll play around with the idea and see if I can make sense of it; unless you've any other light to shed. :-) Thanks for the Adobe info - I'll create a simple test case and drop a note to them.Cheers, IanOn 9/16/06, Daniel Wabyick [EMAIL PROTECTED] wrote: That most definitely sounds like a bug ...
