The Debug sampler output will show that it is not a variable scoping issue.
There seems to be a problem with the While Controller not
re-evaluating the condition properly. Not sure why this is yet.
Try setting the default value to "false" in step #7, and using the
condition "${moo}" in step #5 (in both cases remove the quotes).
