I guess the reason this is missing, is that nobody ever needed it. In
my opinion, the need of a cancel-callback is a sign of a code-smell
;-)
However you can add a method like the following one, to get the
desired behavior:
WASubmitButtonTag>>cancelCallback: aBlock
self attributes at: 'name' put: (canvas callbacks
registerCancelActionCallback: aBlock)
Cheers,
Lukas
