In reply to this post by Ethan Gruber
Ethan,
You don't want to set the value of the node bound to the <fr:autocomplete>, because this is what the <fr:autocomplete> does, so depending on when you do it, it will override your value. Instead you want to add an item that has the name/value the user searched. Let me take an example (code attached): 1. Your autocomplete is for a list of countries, which you pull down as the user types. 2. Say the user types "United". That is not the name of a country, but you still want to have that information stored in the instance. What do you want in the instance? Say you want what the user typed. 3. So on fr-search-changed, in addition to updating the list, you add an item to the list, with label = value = United. 4. The <fr:autocomplete> will find it, the label matched what the user typed, so it will populate the node with the value for that item (which you also set to United). I hope that this is a bit clearer!
