Bug ID: 65322
Summary: Regex Extractor uses old values when extending
variable in template
Product: JMeter
Version: 5.4.1
Hardware: Macintosh
OS: Mac OS X 10.1
Status: NEW
Severity: normal
Priority: P2
Component: HTTP

A jmx that demonstrates the bug.
Using a regex extractor post processor to extend a string on multiple
consecutive http requests overwrite retains the value from the first cycle.
Example jmx attached.
This extracts a nonce value from the www.google.com page.
And uses the regex extractor template to extend the variable by using eg
$1$,${varName} into variable varName.
With a single user the first cycle works fine, any further cycles use the
variable value from the first cycle.
eg 4 requests and extractions
x.y x=cycle y=request/extraction

Attached is a BUGSample.jmx which can be loaded and run to see the problem in
the debug samplers wrapping the individual requests and the extractors.
