Hi Roelof,

I could file-in or look at your attached code to try to help,��
but its not clear what your question is or how to reproduce your scenario.

You say... "when I call on the class side the method which should read the masses"�� �� which is a non-specific **description**.
So I feel its extra work to try and decipher your question and perhaps I won't work it out and it would be wasted effort,
which discourages me from trying to answer.
Being more specific,��something like... "when I call MyClass class>>myMethodXyz"��
would��make feel like I have a chance at answering.

Same for... "at the process method" - I see no method named��#process so I can't guess what you question is.

I've taken the time to provide this feedback to encourage you to improve your question to facilitate a better response.
I recommend reading... http://www.catb.org/~esr/faqs/smart-questions.html�� (although the tone is a bit dark, there are some useful��tidbits)

cheers -ben

P.S. Before your next (improved :^)�� restatement of your question, could you try an exercise...
Slowly debug into the class-side call you are making, each step recording on paper on a new line the message sent, and on the same line the value of significant variables, to see if anything unexpected catches your attention.����

When the stepping is at a return statement ($^), select that statement and Inspect it, so you are sure of the value being returned.��

HTH.����
And btw, keep at it.�� The "process" of finding out why things don't work as expected is where you learn the most.

Hello,

Im still trying to make part1 of day2 working at a way I can also test
things.
the tests are working but when I call on the class side the method which
should reed the masses which are on the instanc side , the masses
cannnot be found.

So question 1 is why is masses not found.

and question 2�� is how can I use the changed array at the process method
so I can calculate the outcome.

Regards,

Roelof
