We upgraded our Flex app to 4.5 not too long ago. Everything's been going along fine until today. In today's build we've all of a sudden started getting the error above. This event seems to only been needed on devices that use on-screen keyboards. I'm not certain why a normal, browser-based Flex app would be trying to use it.
Anybody have any ideas?
Is it a library project? Are you using this event at all in your project?
No and no. It's just a normal Flex project, and there are no references to this event anywhere in our code base.
Found the solution. We had to add swf-version=11 in our flex config. Odd that we should have to start doing that now all of a sudden (we weren't setting that explicitly before). Seems like a bug in the SDK.
