I use these in a ssjs library and refernce them from the xpage:

<xp:comboBox readonly="#{javascript:!doc.isNewNote()}" rendered="true" id="inDestination" value="#{doc.Country}">

<xp:selectItem itemLabel='-Select-' itemValue=''>

</xp:selectItem>

<xp:selectItems>

<xp:this.value><![CDATA[#{javascript:return DbLookupArray("", "", "cache", "unique", "sort", "KeywordsByType", "Country",2)}]]></xp:this.value>

</xp:selectItems>

</xp:comboBox>

NB If using another database put path delimiters as \\ .
