when we test DB Example Advanced, connected with mySQL.we can read data from mySQL by datamanager. but when we want to add some data into mySQL,we get following msg in serverside.

Hello,
I am sorry but we can't reproduce the issue. Maybe you have modified the code and introduced a bug.
If you need it I can send the original FLA file to start over.

what's wrong? somebody help, thanks!
I had a sort of similar error, saying can't cast to string. It was when I was trying to send an extension response back in xml, from within a python class... I ended up having to use JSON instead for some strange reason.
We're getting this error as well; there's no possibility to send over an FLA to debug as it's a multi-FLA environment... which means we have to debug through guess-work. It would be helpful if at least some more information is posted when an extension error occurs - the event type at least.
One working theory we have is that in certain cases we might have been passing a null object into a sendResponse method because we're getting a JSONException.
What server version is this?
The error is not related with JSON, because the exception indicates an ActionscriptObject which relates to XML protocol.
It is likely that you are sending a null param object to the server. It should be easy to double check your client code that the param argument is not null.
Hint:
Always create an empty object first, add parameters to it (even none, where appropriate) and then send that object.
