the sencha docs http://docs.sencha.com/touch/2-1/#!/guide/class_system doc does not talk about the initialize function at all yet most custom components use it. why is it not in the docs? should I use it when I build a custom component? also whats the difference between constructor and initialize function? thanks.
Additionally I will say that chapter 3 of the book Sencha Touch In Action goes much more in depth into the component lifecycle. I have purchased the early access edition and I have found it worth it. More info here:
