Canvas api for a button

Hello all,

I'm trying to create a simple cancel button on a form. I want it to
perform "self answer: true" when clicked. This is my latest iteration:

html button text: 'Cancel'; callback: [self answer: true].

but when I click it, it doesn't send the answer to the component, it
doesn't do anything :)

Any thoughts?

Regards,

Brian

Try this...

html button callback: [self answer: true]; text: 'Cancel';

Remember, #text: is a synonym for #with:, which closes the tag, it must
always come last.

Ok, I followed the text: and it was sending #value:, but I should
have kept going :)

Thanks!

Silly question, but do you have it in a form? Do buttons work outside a
form?

Not for input tags. There it is a synonym for #value: an thus does not
have to be the last message.
Leaky abstractions ;)

Yes, I had it in a form; I changed it to this, and everything works
fine:

html submitButton callback: [self answer: true]; text: 'Cancel']
