I am new to Prototype, I have a webpage and an iframe in it. I am loading Prototype in my iframe and am trying to use Selector API to get DOM references for elements of my parent window. Eg: Selector.findChildElements(document,['div']) is returning references to DIV elements of iframe's document. But,Selector.findChildElements(parent.document,['div']) is not returning any references to DIV elements of parent's document. Instead, giving an error "TypeError: Cannot call method 'identify' of null". When I deep dive into code, I find 'Element' is actually adding 'identify' method (which is in my iframe context, which is addigning a dummy 'id' attribute). First of all my understanding of Prototype and its Selector API is poor, please suggest a way I can use Selector API to fetch references to DOM elements of my parent document.
