In the DebuggerClient, you can call registerActorClient[1] to register an actor client, and several things are checked about it (see [1]). One thing that isn't checked though is if it has an `emit` method, as called in [2] if the client has an events array.

Patch fixing this. Panos, could you please take a look?

Thanks Panos! (In reply to Panos Astithas [:past] from comment #2) > I'm curious, did you spot this from reading the code or did this actually > bite you in some client you are working on? From reading the code actually, I was trying to figure the smallest acceptable actor client and I needed events.
