Hi,  I am still having trouble running my program under
1.0.  I keep hitting a run time error like the following:

Unable to find method implementation. Class mycalss,
Selector 99999999
         ^^^^^^^^  a very big number, looks like something
                   was trashed.

I did not see anything like this under 0.9.
What I am doing is nothing more than let two objects talk
like this:

Object1 of class CLASS1 sends a message to object2 of
class CLASS2 when object1 is hit by rightMouseDown.
Then object2 send a reply message back to object1...
I defined the classes like this:

@interface CLASS1:Object
{...}
+new;
/* all instance methods follows */
@end

@implementation CLASS1
+new;

-IamHit:sender 
{
...
 if (sender==self) {
    object2 = [[sender pipe] doCopy];
    /* [sender pipe] returns the object of CLASS2 */
    [object2 doSomething];
    }
...
}


and in CLASS2:

@implementation CLASS2:object
{...
}

- doSomething:sender
{
  [self prepare];
   ^^^^^^^^^^^^^ <-- error message comes up
                  although I have prepare
                  defined and declared.
...}

- prepare
{
  [self doThis];
  [self doThat];
  ....
}



What I am doing wrong? Any suggestions?
Thank you!
