We assume, even when a helper function is used, that the list is static. If you want to force server-side invocation of your helper function to refresh the list you need to include a parameter in the definition. This signals the list is dynamic and should be refreshed using the helper function. See "16.10.1. Advanced enumeration concepts" in the User Guide: "In the above cases, the values in the lists are calculated up front. This is fine for relatively static data, or small amounts of data. Imagine a scenario where you have lists of countries, each country has a list of states, each state has a list of localities, each locality has a list of streets and so on... You can see how this is a lot of data, and it can not be loaded up. The lists should be loaded dependent on what country was selected etc..."
