Hi Carl,

This is very strange because WACanvasLinkSubmitTest is doing
exactly what you are trying to accomplish. This can be seen
at http://localhost:8008/seaside/go/tests/allcanvastests
where you select tab entitled "Submit"

Enter (say) 23 in the input field then click the "++" link, you
should get a value of 24 demonstrating that the form
was indeed submitted with all the callbacks executed.

The only difference I see is the order of the message sends,
and I believe this is important so that the javascript created
by #handlerForForm: also includes the callback key that has
been created earlier by the #callback: message

            html anchor
                id: #increaseLink;
                addShortcut: 'Ctrl-Up';
                callback: [count := count + 1];
                submitFormNamed: formId;
                text: '++'.
