You should be using the NSTextInputClient protocol in modern code.

Are you overriding -[NSView inputContext]? Perhaps you did it accidentally, if you created an inputContext property?
Try invoking [NSTextInputContext currentInputContext] either arbitrarily or instead of [self inputContext]. As I recall, it is within +currentInputContext that Cocoa deactivates that old input context and activates the new one (if the first responder of the key window has changed).
