Raymond,
hello again, I follow your advice " I suggest that you
open a JIRA and attach the test case there so that we can debug.". I opened
a JIRA (link <http://issues.apache.org/jira/browse/TUSCANY-3067>). This is
my first bug there. Can you tell me if I've posted enough information?
Thanks,
Sebastián Groh
