Hi Paul (and Jonathan), Let’s *assume* that the bootstrap code is a good citizen and fires an “on-change” event for the real, though hidden, select element.
Now, Let’s simplify your ajax to test that assumption out because there are many ways to set things up let’s do the simplest. 1.) Get rid of your AjaxObserveField, you don’t need it. 2.) Give your real select a true CSS ID. 3.) Add a binding to your AjaxUpdateContainer: “observeFieldID” and then give it the CSS ID of the element you want to observe (the real select that is hidden). Try it out and report back.
