I added the alert on success and it's being invoked properly.
I suspected the service may be being cached and not returning fresh data. I've added "no cache" headers to the response but it doesn't seem to impact the result.
When running tests using the Tiggzi web based link (or the test link on my phone's browser), things work fine. When using the Tiggzi tester app on my phone, I get the alert that the service succeeded, but it doesn't update the list. One quick way to test if things are working properly is to click the "order by name" then "popular" on the Now Broadcasting screen, the lists should rebuild (they don't on the Tiggzi app tester).
Is there a way to create a variable with a random value to ensure a new web service is called each time? In other programming languages, the web service url would include a random number at the end to ensure things weren't being loaded from cache.
Thanks for your help.
