I'm using jasp tag <xtags:forEach> to print a list of elements like in xsl-xml
transformation, and i would obtain something like this:

element1, element2, element3,  ... elementN (without ,)

I tried to use  <xtags:valueOf select="last()"/> and <xtags:valueOf
select="position()"/> to check if i am on the last element of the loop, but
doesn't work.

Both <xtags:valueOf select="last()"/> and <xtags:valueOf select="position()"/>
return always 0.

Thanks
