[Rubycocoa-talk] validateValue:forKey:error: problem

[Aron N. <aro...@gm...>]

Hi All,

I'm trying to implement property validation methods  
(validate<Name>:error:, or, rather, validate<Name>_error in Ruby) in a  
Ruby class.  I am able to call the validation methods directly from  
objc, but they are not called when running  
"validateValue:forKey:error:".  Turning on RubyCocoa logging shows no  
activity on the bridge when validateValue:forKey:error: is called.

I replicated the issue using a simple example.  Am I missing something  
obvious here?

I'm using the Ruby and RubyCocoa shipped with Leopard.

Thanks from a newbie,
Aron


Sample Ruby code:

require 'OSX/Cocoa'

include OSX

class A < NSObject
     kvc_accessor :prop

     def validateProp_error(value, error)
         puts "In validation"
         return true;
     end
end

Sample objc code:

#import <Cocoa/Cocoa.h>
#import <RubyCocoa/RBRuntime.h>
#import <stdio.h>

int main(int argc, const char *argv[])
{
     NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

     int stat = RBApplicationInit("validate.rb", argc, argv, nil);

     if (stat != 0) {
         fprintf(stderr, "Error in ruby initialization\n");
         [pool release];
         return stat;
     }

     Class rubyClass = NSClassFromString(@"A");
     NSObject *obj = [[rubyClass alloc] init];

     // The following doesn't work:
     [obj validateValue: nil forKey: @"prop" error: nil];

     // The following does work:
     // [obj validateProp: nil error: nil];

     [pool release];
}
