I'm trying to parameterize jmeter-2 to test my application for more than one
user.
I record my login-search-logout scenario from my application with proxy server
and add a "User Parameter" element that use __CSVRead function to read the user
defined parameters from a data file for JMeter.
all threads work well with all loaded users but when I want to call an action in
one page from h:commandlink, my backBean method call only once.

Is there a special config for jsf or jmeter?

What is the jsf_sequence value in request parameters?
(I add a regular expression extractor :
jsf_sequence
input\s*type="hidden"\s*name="jsf_sequence"\s*value="(.+?)"\s*
$1$
and replace all values with ${jsf_sequence}
)
