I didn't see before that there is an error message referring to a BeanShell
sampler in JMeter's log sent in the first message. If you are using
expressions like this "field_${Fields_g1}" inside your BeanShell code, I
advise you to pass variables, or expressions using variables, as arguments
(i.e. don't use JMeter variables or functions inside BeanShell code, or
prefer not to) to avoid interpreter exception during execution. BeanShell
code is compiled to a "static" version (if "Reset before each call" is not
checked).
I built a script similar to which you presented, but ATM I'm not seeing
errors or unexpected behaviors. I'll try to post it and send the link into
this thread.
