Hello!
I have a QueryTask script and it only works the first time in a given browser or computer (it worked once in Firefox, Chrome and IE on work computer, and once in Firefox on my home computer). Now, whenever I refresh or access the page again the results don't show. I don't have this problem if I return the results as text; I can refresh as many times as I want and it works fine. Yep, I've restarted and cleared caches! It's my first time trying to build a web map with querying functionality so I might be missing something really obvious... Please let me know if I need to explain something better, too! Thanks a bunch!
