possible issue with While Controller

[Lorenzo Fundaró <lo...@gmail.com>]

Hello,

I think I discovered what it might possibly be an issue in JMeter 2.11
r1554548

So here's the story:

I have a BeanShell PreProcessor that puts a variable like this:
vars.put("DONE_UPLOAD","false");
then,
I have a While controller that evaluates this variable like this:
${__javaScript("${DONE_UPLOAD}" == "false")}
then inside the While controller I have an HTTP Request sampler that
responds to either 200 or 202.
After the sampler (still inside the WhileController) I have a Beanshell
PostProcessor that does this:
if (prev.getResponseCode().equals("200")) {
vars.put("DONE_UPLOAD","200");
}
So the the set of instructions above could be described as "Do the HTTP
request until the response code changes to 200"

This flow does not work as expected, even thought I believe there are no
syntax errors.
However, it DOES work whenever I added a "Debug Sampler before the While
Controller".

Why is this ? it seems like the While controller is not properly evaluating
the variable on each iteration but the Debug Sampler does it for him.

Note that the Debug Sampler must also be outside of the  While Controller.
I could send you guys a little Jmeter test plan with an example proving
this strange behaviour.

Thank you.
