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.,
<t:loop source="things" value="currThing">
<t:pagelink page="Details"
context="currThing.id">${currThing.name}</t:pagelink>,
</t:loop>
The above, of course, produces a trailing comma.
I know that some CSS tricks can turn a <ul> into a comma-delimited
list, but the only CSS solutions I've seen use things like ul
li::before and other CSS things that don't play well with @#$%#$@
internet exploiter.
If the _source or even _iterator instance variables of the Loop class
were protected rather than private, I could just subclass Loop and
override the afterRenderBody, check _iterator.hasNext and emit ", " if
there is a next.
Any thoughts?
Bill
