These Null Pointer Exceptions Tell Me Nothing?

I'm assuming this has something to do with the fact that the UnityEvents run on delegates, but every time I get a null pointer exception, rather than pointing to the actual origin of the exception in the code, the error in the console simply states that there was an exception in the event. Here's an example:

Code (CSharp):

1. Type IPointerClickHandler expected Button received. i:0. Object reference not set to an instance of an object
2. UnityEngine.EventSystems.EventSystem:Update()

Is this a bug? Or is this actually supposed to happen? Because I would like it if it could tell me at least a bit more about which specific method caused the error, if not the exact line it occurred on.

 

I was unaware b18 was out yet When I use "check for updates" from the help menu, it tells me that my current version is up to date. Where should I be looking to check to see if I'm using the most recent version?

 

Fair enough XD Thank you.
