Can __javaScript call recalculate?
Hi all,
I'm having trouble with a Jmeter test plan where I'm trying to use
String.indexOf(String) in a __javaScript call. However, once the
expression has been evaluated once, it always returns the same value,
regardless of one or both of the strings being different each time it
should be called.
It seems this is the same for all __javaScript calls - in the attached
.jmx, every call for a random number returns the same value.
Is there any way to force __javaScript functions to always be
re-evaluated each time?
Cheers,
James

Thanks - that worked a treat!

Not ideal either as they tend to get mangled ... this one was not too bad.

Yes, the UDV is a config item and is only processed once.
Try using a User Parameters Pre-Processor instead or just put the
function call in the sampler.

Sorry - my bad - I checked here
(http://jakarta.apache.org/site/mail.html) and it didn't say anything
about not sending attachments... As it's a small file, I've pasted JMX
content below - hope nobody minds.

The function is in the value field of a User Defined Variables
component. Perhaps I'm using the wrong component - I basically want to
set a bunch of parameters to new values between a couple of HTTP
samplers.

JMeter 2.3, JDK 5 (1.5.0_11-b03)

They should work - depends where you are calling the function from.
Also, which version of JMeter are you using? Java?
