Is it possible to show and initial text in in a dijit.form.FilteringSelect wich is not an value. For example the search box on http://docs.dojocampus.org displayes the value "search" when it is not being used.
I have tried using select.attr( "displayedValue", "My initial text" )
but becuase it is not an actual value the box will be marked as if it contains an invalid selection.
