ComponentActivator: could not instantiate

[cnichols]

Hey Guys,

I'm using the Windsor controller factory in a .net mvc project and
have an error that is driving me nuts. The factory errors when
instantiating one of my controllers but works fine with the other 5
controllers. I've compared the code in the failing controller to my
working controllers and everything is the same. I checked and
rechecked my interface, repository and entity and everything looks
good.

Although the stack trace is listed below I don't suspect this is
enough information to solve the problem. Can somebody point me in the
right direction?

I figured this out. My repository didn't inherit the interface.

Thanks.
