And? Whatever content you put after the <t:if/> will still be rendered -
and properly comma-delimited. :)

Well, sometimes this will be page links, sometimes literal text,
sometimes other components. The loop body might contain anything.

Hi Bill,
Try this:
<t:loop source="things" value="currThing" index="var:index">
<t:if test="var:index">, </t:if>
<t:pagelink page="Details"
context="currThing.id">${currThing.name}</t:pagelink>
</t:loop>
On the first iteration of the loop index will be 0 which evaluates to
false. Any other iteration will output the comma.

I need to comma-delimit components in a loop that will be <t:pagelinks>. I.e.,
