Hi,
That was all that showed up in the debugger, but in the class otherClass there is a method called doSomething.
I have also tried what you suggested - [otherClass doSomethingElse] - but i get a warning in xcode, http://cld.ly/7c4la.
(JGManagedObject is what replaces otherClass)
Thanks.

Why not simply... [self doSomething] ?

Why not simply [otherClass doSomethingElse] ?
...aka... Why are you using performSelector in the above?

You are sending a message to an object that doesn't respond to that message (aka no implementation for it). The error message you listed should have more information about the class of the object you messaged incorrectly, what does the rest of it say?
Hard to tell what may be going wrong with the limited information you have posted. I rather not waste time guessing (can think of at least 4 common things you could be doing wrong).
