Apparently you find a problem in self evaluating on color or related.
Let me explain:
The idea of printing an object is that in some case
anObject printString let you recreate the object
example
1
true
#(1)
#(1 2)
1...@50
this means that either you get the same object or when you executed
its printed representation you get it back.
This is handy when playing with an inspector or in a workspace
now for array if you get an array of points in the past
printing it would return
#(10 #@ 50 20 #@ 50)
which is different from what is was really
{...@50 . 2...@50}
or Array new: 2 at:1 put: 1...@50 ; at:2 put: 2...@50
So when an object is selfevaluating it measn that its printed
representation can be used to recreate it
When an array contains only self evaluating objects then it is printed
with { } since it can also be recreated
now if you get an object inside an array taht is not self evaluating
then your collection cannot be self evaluating.
so we say it anarray of ... instead of a #( 10 # @ 20....)
But in your case something went wrong because color and others are
self evaluating.
could you provide with a snippet of code that we can check where the
problem is coming from?
