Xpages Combobox -setting the default value

I have a combobox with values being populated from a managed bean like so:

keywordlist.setConnDB("jdbc:sqlserver://xx.xx.x.xx:1433;DatabaseName=xxx");
keywordlist.setConnUserName("xxx");
keywordlist.setConnPassword("xxx");
keywordlist.setSQLQuery("SELECT DisplayText as Keyword From Glossary WHERE  SUBSTRING(DisplayText, 1, 2)= 'RV'");
keywordlist.keywords;

I'd like to be able to set the default to '--- Select ---', but no matter what I do the keyword list always picks the first of the returned keywords as the default.

Any assistance would be much appreciated.

Thanks,

Dan

Basically, the following pattern could be a start point for such a combobox:

    <xp:comboBox
        id="comboBox1"
        defaultValue=""
        value="#{document1.someField}">
        <xp:selectItem
            itemLabel="--- Select ---"
            itemValue=""></xp:selectItem>
        <xp:selectItems>
            <xp:this.value><![CDATA[#{javascript:
            // Your SSJS code...
            // Should return some kind of list...
            return items;
}]]></xp:this.value>
        </xp:selectItems>
    </xp:comboBox>

Alternatively, you can grab the keyword values from a Java bean:

        <xp:selectItems value=#{yourBean.yourValue}></xp:selectItems>

Still, it's important to return a list value. It might also have "label|value" format.

It might be because you're binding to the bean directly. You might have to add that value to your keyword list itself. I think I have an example of this in a NotesIn9 show: http://notesin9.com/index.php/2014/03/13/notesin9-138-xpages-combobox-improvements/

I'm not sure. If I don't have a default in the java code you can probably see how it might be done.

Try that. If that doesn't work at all then maybe you don't bind the combo box to the bean directly. Maybe bind it to a viewScope var... since that can be anything it'll take a blank... then you just need to move the viewScope var value back up to your bean in the onChange event or something.

Just a quick thought...

Add another value pair (on first position), type "formula item" with the following SSJS return value:

"-- Select --|"

Notice the pipe! That should display this at first position and should also be defaulted as "empty" is the default value. If not, set the "alias" (the value after the pipe) to something that you can define as default value porperty for the combo item.
