Hi Scott, I'm the author of the question on Stack Overflow :) I've just published a lighter version of the original code (it doesn't work anyway, now even if I make the same ajax call it doesn't work): http://jsbin.com/vexeq/7/edit?html,output
After execution, you'll find this in console.log: Uncaught TypeError: Cannot read property 'photos' of null I don't think it is a parseJSON error, because in the original implementation I use the same method to parse other json string and it works. Thank you for your support! :) Il giorno lunedì 14 aprile 2014 18:25:13 UTC+2, Scott Miles ha scritto: > > Fyi: > http://stackoverflow.com/questions/23063667/troubles-with-multiple-ajax-requests-from-different-instances-of-a-custom-elemen > > > On Mon, Apr 14, 2014 at 8:42 AM, Eric Bidelman <[email protected]<javascript:> > > wrote: > >> Can you provide a jsbin of what you're trying to do?
