possible issue with While Controller
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.

The issues list is intended for recording additions to the bug
tracking system, i.e. Bugzilla in the case of JMeter.
Please subscribe to the JMeter user list and post there instead.
If necessary, you will be asked to raise a Bugzilla issue, to which
you can then attach any test plan, logs etc.
Thanks.

@Flavio, that's what I did, I used a BeanShell Sampler and it did the
trick.
@sebb your suggestion also works.
Thank you guys. I appreciate your help. Great community :)

You could also change the While condition to:
${CONTINUE}
and change the Post-Processor to
vars.put("CONTINUE","false");
You don't then need to initialise the variable.
Note that you can also initialiase variables on the Test Plan.
The initial values are copied to each thread; subsequent changes apply
to the thread only.

@Lorenzo if you only need to set a initial value to a variable (in you case
"DONE_UPLOAD") you could do this in BeanShell Sampler. If this is the case,
there's no need to use a Post-Processor.

@Flavio your suggestion works best for me when using a Beanshell Sampler.
Defining a User Variable it's not what I want because they have Thread
Group scope. So now, the While Controller works putting a Beanshell Sampler
before it and using a Beanshell PostProcessor. Thank you.

If you are using BeanShell Pre-Processor so it will be triggered only for
the samplers.
I'm supposing that While Controller wasn't been executed, because BeanShell
Pre-Processor (or even Post-Processor) will not be triggered until a
Sampler is executed.
That's why when you add a Debug Sampler before the While Controller it
works.
Use an User Defined Variables configuration element to initialize
"DONE_UPLOAD" 's value or a BeanShell Sampler.

I am getting the same behaviour with 2.12.
