Providing a default value in Combobox with dynamic values

You have a ComboBox 'MyCombo' with computed choices of field 'MyChoices' and using the option: Refresh choices on document refresh. After changing the choices in field 'MyChoices' and doing a refresh you can access the new choices but the Combobox is empty by default. So I use a JavaScript function to select the first Value (if there are choices at all) to indicate the user that there are choices in the Combobox.
This goes into the JSHeader: 
function initField( fieldName ) {

 if  (frm.elements[fieldName].selectedIndex == -1) {
	if (frm.elements[fieldName].options[0] ) {
   		frm.elements[fieldName].selectedIndex = 0;
		}
	}
}

In the event where you change the choices for the field 'MyCombo' you call notesuiworkspace.URLOpen("javascript:initField('MyCombo')") ( or @URLOpen(...) if you use @Commands)
