lost 1 objects

Hi there!

I know, that i lost 1 object. How can i get rid of it?

I have a class called "Thing". During development (i do metaprogramming,
which work like a charm) i made some mistakes, i guess. Now i wanted to
use the nice method "allInstances".

This method shows me the following.


Thing allInstances
        an Array(a Thing)

So i inspected the "a Thing" and found only 4 Objects pointing an the object

an Inspector
an ObjectExplorerWrapper
an ObjectExplorerWrapper
an ObjectExplorerWrapper

This is because of my inspectors I guess.

Even if i save and reopen my squeak image, i don't lose this _damn_
object. I have no idea, why this instance won't go away.

Is there alway one instance of a class in Smalltalk?

Sorry fo asking this wired stuff.

No, something has a reference to it, otherwise it would be garbage-
collected. Try this recipe:

Thanks, this guide helped me!

I found a weak reference in the system. I deleted the refernce by hand
and the bad object is gone.

Looks like the garbage collector did his job well.

Hopefully i produced not more weak references, which are hanging in my
system around.

Bye,
Stephan
