Hi,

I get a ActionControllerException: “stack level too deep” when I  
attempt inline RJS like this:

\<%=observe\_field(“loan\_term”, :function =\> update\_page { |page|  
page[:max\_term\_in\_yrs].insert\_html(page[:loan\_term].value/12); })%\>

What am I missing – where’s the wind?

Thanks,

Lille
