Ah indeed. 
So we will have to have a look.

Maybe his question is (also) why the automatic refactoring did it wrong, the rules warned about the wrong use of #printString, suggested a fix, but the solution is still using #printString, hence the same problem.

Hi

this warning is just that printOn: is working on a stream

and when we do

printOn: aStream

aStream nextPutAll: x printString

printString creates yeat another stream then ask the contents and passes it to the first one


printOn: aStream

x printOn: aStream

is faster and cleaner in that case.

I started working through PBE8, and in section 3.13 there is a method:

Counter >> printOn: aStream

super printOn: aStream.

aStream nextPutAll: ' with value: ', count printString.

But it returns two warnings:

[printString] No printString inside printOn

Use cascaded nextPutAll:���s instead of #, in #nextPutAll:



It has the option to automatically resolve the cascaded nextPutAll: which results in:

printOn: aStream

super printOn: aStream.

aStream

nextPutAll: ' with value: ';

nextPutAll: count printString



But it still has the warning about printString.
