You are certainly not required to eliminate #name altogether; all you have to
do is to ensure that any object that receives the message #name knows how to
answer its own name in an appropriate way. To rephrase Ben’s second para in a
more long-winded way:
a. Run the code that generates the deprecation warning.
b. In the warning pop-up, click on ‘Debug’.
c. Examine the debug stack in the top pane. It is probable that the first
two lines will read:
HannesClass(Object) deprecated:on:in
HannesClass(Object) name
where HannesClass is the name of some class in your domain model.
d. You now know that some code you have written is sending the message
#name to an instance of HannesClass, but the class does not have such a method.
The solution is to decide how an instance of that class should answer its name,
and implement that as a method on the instance side of that class. If nothing
else is obvious, the usual default is ^self printString.
e. If the top line of the debug stack does not refer to a class in your
model, work your way down the stack until you find a class that is yours.
Hope this helps

Subject: Re: [Pharo-users] Object>>#name deprecated in Pharo 6 -- what do I
need to do?
Just checking my presumption... is PPCMNode>>#gtTreeViewIn:
you own application method? So where it sends #name, instead send
#printString (or #asString).
Alternatively, #name is being sent to some domain object that doesn't implement
#name, so it falls back to the super one from Object. So implement
YourDomainObject>>#name: so the one from Object is not executed.

Implement your own domain representation of an object, or use
#asString or #printString instead.
I wonder how I can fix this without going to much into details.
