Hi Bill -- The game works fine in my image. 1) The first thing I would look at is when the debugger comes up I would select the second line from the top of the list that is shown in the top pane of the debugger. When you do that the debugger opens and will have the offending message highlighted. I would select the object that is getting that message and cmd-i ( or ctl-i ) which brings up an inspector which will show you if you really have aSBECell or not. If you are not getting the right object there is probably something in the code that you did not copy correctly. Did you type the instructions in ? 2) same steps as one.
By the way the code for the examples can be downloaded from squeaksource.com

You can also grab all the example code in ascii from the book's web site (since copying and pasting from PDF does not work reliably).

Just taking the already-working example from squeaksource is too much like cheating ... ;-)

thanks for suggestions
turns out that my problem was that I was using an old 3.8 image
I learnt from the book how to file out and file in - as soon as I tested my code in the 3.9 image it worked fine!
A friend sent me some other information from the bugs site pointing out a bug in SimpleSwitchMorph in earlier versions: http://bugs.squeak.org/print_bug_page.php?bug_id=3530
Summary: 0003530: SimpleSwitchMorph does not actually implement switch functionality

In 2007, many people's introduction to Squeak may be with an image derived from 3.8 (*). So I wonder if the book should not mention this patch prominently at the start of the First Application chapter.
By the way, I probably learned a lot about Squeak by wrestling with this for a while this weekend without access to internet or a 3.9 image :)

Hi David -
If you can find a bit of time to assemble a set of patches which will make those examples work, I'd be happy to fold them into the system to make sure these examples work out of the box.
Cheers, - Andreas

The olpc etoys image now contains the compatibility code, as update 1666simpleSwitchMorph-apb for etoys2.2.
For the moment, the TestCase subclass included with Andrew's fileout is omitted, since SUnit is absent from the olpc and Squeakland plug- in images. In due course we'll get that SimpleSwitchMorphTest code into the development version of the olpc code base, however.

I tested Marcus Denker's original changeset SwitchMorphEnh.2.cs at http://bugs.squeak.org/file_download.php?file_id=1399&type=bug in a Croquet SDK image Croquet.1.0.18.9 from the Wisconsin Croquet Collaborative.
If works great and the example First Application in Squeak By Example is perfectly playable as it should be. Hope that helps.
Would you like me to test against any other images?

It may be useful to see if it works for the OLPC line of images as well.

The SwitchMorph code for compatibility with Squeak by Example was pushed to the olpc update stream last month.

Hi David,
I made a note to underline this for the next edition. It *is* stated prominently at the beginning of the Quick Start chapter, but I guess the chapters should be more independent of each other for the Quicker Starters!
Thanks for the feedback!

Yes I did see that, but to be honest I thought I was more likely to be at fault than the image forks I was playing with (and I didn't have internet access to try >= 3.9 image at the time) ! Since the 3.8 forks have become as mainstream as 'mainstream' then a footnote where the dependency arises will be a nice extra touch.
On the other hand, the issue shows a real, if small, benefit of a production fork tracking mainstream where compatible.

I was under the impression that Marcus's changeset was likely to be an adequate patch. http://bugs.squeak.org/file_download.php?file_id=1399&type=bug However, I will try it against the OLPC and Croquet images on my desktop and report back.
I will need to read more of SBE to learn not to use 'diff' and 'patch' :)
