Ok, I've figured out that I can use this.options={} within the
initialize function to declare defaults, and then follow this with
'Object.extend(this.options, options || {});' to customise these
defaults
But I still don't understand why I get different behaviour in the
above example for this.options.value and this.value - can you tell me
why?
Thanks
