I have a fixed set of entries in my ComboBox, but when I am typing a "non-existing" entry and do mouse click some where in the browser screen it sets EMPTY value in the combo box.

Is there any way to force the combo box to select first entry in the list?

ComboBox Properties:
------------------------
fConstructCombo.setWidth(250);
fConstructCombo.setTypeAhead(true);
fConstructCombo.setMinChars(1);
fConstructCombo.setForceSelection(true);
fConstructCombo.setTriggerAction(TriggerAction.ALL);
