Bug in ExtendedChatPod

[Rick_Bullotta]

Hi. In my application, if I attempt to set the
historyFontSize property in the MXML tag for the ExtendedChatPod
component, it will throw an error on initialization. If I set the
property via AS at some later point, it works fine. Here's the
error thrown:



TypeError: Error #1009: Cannot access a property or method of
a null object reference.

Hi Rick,

Seems like a bug. We will get it fixed and update it in the
next drop of SDK.



Thanks

Hi Rick,



This issue has been fixed and It will be updated in the next
version of SDK drop. It was because the chat model wasn't
synchronized by the time we set historyFontSize property via mxml.

Thanks again for reporting.

Happy to help. While you're in there looking at the
SimpleChat pod code, I'd recommend styling it such that all of the
UI components use the same font face/size by default. I also
attached an extended version of SimpleChat that includes an
"unsubscribe" method that properly cleans up a subscription in a
way that allows reconnection. You may wish to incorporate this
behavior into your classes in Cocomo as well.

Hi Rick,



We will look into the styling suggestion. Regarding
unsubscribe, we are evaluting the best way to uniformly unsubscribe
all cocomo components so that user can dynamically switch rooms in
cocomo.



Thanks
