[flexcoders] Re: SharedObject problem/bug? Cannot store a subclass of ByteArray.
I'm having a similar problem with a subclass of Dictionary.

Hi Sean, Thank you for the link; still no luck. I had tried implementing IExternalizable before, but after reading your article I decided to try again. I have figured out a little more: --I can extend, say, a Sprite, and it works fine. --When I save the SharedObject, if I use the Sprite-based class, there are two calls to writeExternal(). But for the ByteArray-based class, there is no call to writeExternal(). --When I load the SO, the constructor for the Sprite-based class gets called. The constructor for the ByteArray-based class does not get called. I suspect that Adobe's serialization/deserialization code has something that checks for type ByteArray (e.g., if (x is ByteArray)). On the write-side, it would then call something like writeBytes(), and only call writeExternal() if not a ByteArray. On the read-side, it may do something similar when type casting. At this point, I will probably try a workaround for my situation. (E.g., encapsulating the ByteArray) But if anyone gets this to work, I would be interested to know. --Geoff --- In flexcoders@yahoogroups.com, seanmcmonahan s...@... wrote: I'm having a similar problem with a subclass of Dictionary.

Hi Alex, Fair enough. I submitted it (I think), although I got this message: You have successfully created the issue (FB-23715), however you do not have the permission to view the created issue. This is probably because you entered a bug report that details a potential security vulnerability - or is related to a non-public component in a commercial product. I do not feel experienced enough to know which categories to submit the bug under, but I included source code to reproduce the bug. Alex, thank you for your continual help to the community. --Geoff --- In flexcoders@yahoogroups.com, Alex Harui aha...@... wrote: Please file a bug with a small test case.
