Currently, both of these expressions in my UDVs work properly for me,
though according to you they shouldn't:
${__javaScript('${__P(delay)}'*'${__P(mythreads)}')}
${__javaScript(Math.floor('${__property(maxcnt,,512)}'/'${__P(mythreads)}'))}
I suspect that Javascript is doing implicit type conversion, because
both of these contexts are numeric (there is no string concatenation
operator). If he were using '+' he would need to watch out.
I'm not saying this is the right way to do things and I agree that we
should get to the root of the problem, but I believe that if he tries
it, it will tied him over for the time being.

Hi Michael,
Try putting your variables in quotes, for example:
${__javaScript('${VARONE}'*'${VARTWO}'/'${VARTHREE}')}
I'm not sure why this is necessary, but it's the only thing that worked for
me when I had a similar problem.
That does not apply to numeric values.
1*2/3 is a valid numeric expression, but '1' * '2' / '3' is not.
The relevant reference is in the bottom green box at
http://jakarta.apache.org/jmeter/usermanual/functions.html#__javaScript
Which refers to text strings " ... and JMeter variables."
That should also say " which represent text strings"

When utilizing the Javascript function in Jmeter 2.3.2 (r665936):
I have a Thread Group set up as follows:
WebService (SOAP) Request
-XPath Assertion
-Counter
Constant Throughput Timer
First of all I would like to note that the WebService Sampler rocks. Thank
you for making it. The counter + the assertion are also great.
The constant throughput timer USUALLY works very well.
However today I decided I was going to see if I could adjust my test by
passing one new variable from the command line, so I needed to do some
calculations within Jmeter.
I set the target throughput to:
Values of Variables:
VARONE = 146.17 (which is set in the "User Defined Variables" for the test
plan)
VARTWO = 1000 (which is currently set in the "User Defined Variables" for
the test plan but will eventually be passed in)
VARTHREE = ${__javaScript(16*60)} (which is set in the "User Defined
Variables" for the test plan)
When I start the test, only one sample goes through and then nothing until I
try to stop the test. At this point, I get this exception:
Exception in thread "Thread-77"

Did I set up my Javascript wrong?
Also: if I do this:
${__javaScript((${VARONE}*${VARTWO})/${VARTHREE})} //(Note
the extra
parenthesis)
I will get a similar error at the same place and time (when I go to stop the
test):
Exception in thread "Thread-77"
org.mozilla.javascript.EvaluatorException:
missing ) in parenthetical (<cmd>#1)
Any help would be greatly appreciated!
Thanks!
