Hello Everyone,
I'm having an issue with setting up a test Chat client. I can login to the AFCS air app as the developer and I can login with my Flex sample. However, when I change my AdobeHSAuthenticator.authenticator.userName to Guest and set the password = null, I receive an "Error #1009: Cannot access a property or method of a null object reference." FlashDevelop is pointing to the sendMessage method and the clear method of the SimpleChatModel Object.
Any Ideas? Thanks in Advance
