Sure, but I don't think it addresses my problem. My problem isn't
creating a list, my problem is delimiting values on each iteration of
Loop, without having a trailing or leading delimiter.

Hi Chris,
may i advise you the listbinding from t5components ?
<ul>
<li t:type="Loop" source="list:\"value 1\", \"value 2\", \"value
3\"" value="element">
${element}
</li>
</ul>

That would work of course, but I'd like to do something like this:
<t:loop source="strings" value="var:string" index="prop:index"
delimit=", ">
<a href="#" t:type="pagelink" page="nada"
context="var:string">${var:string}</a>
</t:loop>
And then each element would be separated by my delimiter without any
extra java code.

How about testing the value of index?
Something like:
.java:
private int index;
public int getIndex() { return index; }
public void setIndex(int i) index = i; }
public boolean isFirst() { return index==0; }
.tml:
<t:loop source="strings" value="var:string" index="prop:index">
<t:if test="prop:first" negate="true">
,
</t:if>
<a href="#" t:type="pagelink" page="nada"
context="var:string">${var:string}</a>
</t:loop>

Sorry, I missed the "check if first" part. How can you do such a
check in Loop? The "If" can test, but what can you test in a Loop?
nothing that I know of will tell you where in the iteration you are.

just reverse where you write the ","
instead of checking if last and putting comma behind
check if first and put comma in front

So this ticket has been implemented in svn:
https://issues.apache.org/jira/browse/TAPESTRY-2028
And now I need whitespace... so how can I get it back? Is there or
isn't
there a way to disable this? Im using loop to output links
(pagelinks),
and i have whitespace behind in the body so there is separation.
Unfortunately, it's getting stripped. Is there a workaround?
On a related note, is there a way to know if im on the last
iteration of
the loop, so i could for example, follow all but the last with a ","?
This may be outside the scope of loop as currently implemented, but i
can see it being useful.
