When this form is loaded, my combobox always has the first name in the arraycollection displayed. I tried setting the selectedIndex = -1 right there in the form, and onCreationComplete setting it to -1.
But I still see the first value being sent to the server. How can I change my combobox to be set to -1 only on initial page load. I have a button that calls a _clear() method, which sets it all to -1 and it behaves as I would expect. Just need to mimic this behavior when anyone navigates to this tab.
