I also have had this problem. See this thread =
http://marc.theaimsgroup.com/?l=3Dxml-cocoon-dev&m=3D113835963721689&w=3D=
2 about your problem. It used to work, but not in cocoon-2.1.8 in this =
way anymore. I am not sure about other versions: which one do you use?

Anyway, I solved it by going through flow. Are you familiar with flow? =
Do the java.util.StringTokenizer part in flow, and pass the variable =
from flow to your jxtemplate. Then you can use the jx:forEach on this =
object.

Regards Ard
