[Rubycocoa-talk] methodSignature is nil.

[Dave H. <gr...@gr...>]

Sigh. I'm back. I'm staring at a misleading error message, and am  
mystified.

/Library/Frameworks/RubyCocoa.framework/Versions/A/Resources/ruby/osx/ 
objc/oc_wrapper.rb:17:in `ocm_send': NSImage#initByReferencingFile: -  
methodSignature is nil. (OSX::OCMessageSendException)

I *think* "methodSignature is nil" is somebody's (Cocoa? RubyCocoa?)  
way of saying "no method by that name found here."

Um? NSImage definitely has such a method. So something else is wrong.  
But I have no idea what it is. It can't find NSImage? I'm not asking  
for its method in the right way? I sent the wrong parameters, or the  
wrong type of parameters, or the wrong class of parameters, or the  
wrong number of parameters?

@myImages = Array.new(6) {|i| 	NSImage.initByReferencingFile("Image" +  
(i+1).to_s + ".gif")}

My XCode project has files named "Image1.gif" "Image2.gif" . . .  
"Image6.gif" in it. The AppleScript version finds them as planned.

Hints and clues gratefully awaited.
