Display multi-value fields with new line in Xpages view Column

Question

Sometimes Xpages drives me insane. So many easy things (things that should be easy anyway) are hard.

Simple questions, how do I display multi-value fields with new line in Xpages view Column?

Answer 1

There's ways to do it with computed controls, where you explode the array and add a
and stuff like that.

Personally I like to just use a repeat control. Set the field as the repeat value. Add a computed control for the "rowData" and add a
if you want a new line between each of them. I'm sure I did this on an early NotesIn9 though I forget which one at the moment.

the key is this. a Repeat control can repeat or "iterate" over any type of array or "multi-value" object.

Answer 2

It's always better and easy to use view control for categorized views rather than repeat controls. To display multi-value field in view column you have to set content type as HTML then just replace commas with <br> tag. And it works exactly as you want.

<xp:viewColumn columnName="$3" id="viewColumn3" contentType="html">
    <xp:this.converter>
        <xp:customConverter getAsObject="#{javascript:value}">
            <xp:this.getAsString><![CDATA[#{javascript:@Implode(value, '<br>')}]]></xp:this.getAsString>
        </xp:customConverter>
    </xp:this.converter>
    <xp:viewColumnHeader value="ColumnHeader" id="viewColumnHeader3">
    </xp:viewColumnHeader>
</xp:viewColumn>
