Hey everyone (especially Adobe engineers), I think I've found a bug with ActionScript 3.0's URLStream.readObject() method while trying to read some legacy AMF0 files that I have lying around from a previous AS2 project.
To set the stage, I have a bunch of AMF0 streams that were generated from Flash Player 8 and saved to files via Flash Remoting and a little bit of custom server-side magic (http://www.radicalconcepts.com). Today, I tried reading some of these files directly into a Flash Player 9 SWF locally via URLStream rather than the traditional approach of using Flash Remoting. So, running locally within the standalone debug player, I read in one of my AMF files and then called readObject() on it, only to have the method read a single byte and return a boolean true, even though my AMF file actually contained an object. The contents of the file was confirmed through inspecting the file with a hex editor with the AMF0 specifications in hand. Well, Edwin van Rijkom's unofficial version, as I don't recall an official spec from Macromedia (http://www.vanrijkom.org/archives/2005/06/amf_format.html). I have the objectEncoding property set to AMF0, and I'm not attempting to deserialize until the stream has finished loading. Inspecting the bytes individually via URLStream's readByte() method also confirms that the bytes are indeed correct and match up with what's seen in my hex editor. As far as I can tell from the documentation, I'm doing things correctly. Trying a handful of other AMF files yielded the same result. However, if I copy all of the bytes out of the URLStream instance and into a ByteArray instance and call it's readObject() method instead, the AMF0 encoded object deserializes just fine. I've a simple test case here: http://dev.psalterego.com/ReadObjectTest.zip The example AMF0 file is named test.amf and is located in the /bin folder. You'll need to compile the enclosed MXML file and then run the SWF locally using the debug player--the trace outputs should be fairly self-explanatory. If you can spare the time, I'd very much appreciate it if some others can verify this so I can be sure that I'm not smoking the crack rock.
