Re: JS log-dumping an object and circular references problem

Dave,

> If these objects are validly recursive

They are provided by the FireFox program by way of a callback to whomever 
installs the "observer".  So I must assume that its valid.

Besides that, the page you referred to shows a method which will (try to, 
but in my case fails) remove any circular references.  Which, to me, means 
that its not something abnormal to enounter.

> That recursion must have been finite, or you wouldn't have got a response.

:-)  You're playing rather fast-and-loose with that "response" definition. 
Getting an error thrown is definitily *a* response.  Just not the normal, 
"valid" (usable) one.

As for a *non*-finite recursion ?   How would you be able to make one ? 
At some point or another you would run outof process memory - most likely 
causing the OS to shoot the whole program (in this case Firefox) down.

> Or it could be a bug.

Seeing that its in an object that Firefox itself generated and presented to 
me, I don't think so.

Also just think of a parent and child object, where the child refers back to 
its parent (which is not uncommon).  Presto, problem.
