>From the Flex docs for ComboBox:
prompt property
prompt:String
<http://127.0.0.1:2522/help/topic/com.adobe.flexbuilder.help/langref/Str\
ing.html> [read-write]
The prompt for the ComboBox control. A prompt is a String that is
displayed in the TextInput portion of the ComboBox when selectedIndex =
-1. It is usually a String like "Select one...". If there is no prompt,
the ComboBox control sets seletedIndex to 0 and displays the first item
in the dataProvider.
So, all you have to do is set prompt = " " in the tag and set
selectedIndex = -1 in your focusIn function after you set the
dataProvider. I do this all the time. Works like a charm. You can also
set the prompt to something more meaningful, like "Select a Family
Name..."
<mx:ComboBox
id="txtFamilyName"
y="24" left="10" right="10"
editable="true"
focusIn="fetchAutoCompleteData(event,'Family')"
dataProvider="{modelLocator.searchModel.family}"
focusOut="focusOutHandler()"
prompt=" " />
