While Controller not getting execute when use more than twice in Test Plan

**Madan Singh** ([Bug 65583](https://bz.apache.org/bugzilla//show_bug.cgi?id=65583&redirect=false)):
Test Objective:Loop http sampler unless response contains a specified string "Success"

Problem Description:Using While controller and regular expression extractor to implement the test object but observed I can only use this logic only twice in my test plan.

When I use while controller with same logic 3rd time(for 3rd different sampler), it do not execute sampler even the condition is true and as a result my scripting is blocked, I cannot execute my test and really feeling low that JMeter doesn't support such simple functionality.

I am a JMeter user from last 10 yrs.

Please help here for immediate resolution.I have attached screenshot for the while controller block I am using.

While controller condition used is ${__javascript("${status}".indexOf("SUCCESS") == -1,)}

Severity: blocker
OS: All

Start by reproducing the Test Plan described in the issue: use three different samplers, While controllers, regular expression extractors, and the condition ${__javascript("${status}".indexOf("SUCCESS") == -1,)}. Inspect the attached while_controller.JPG for the reported setup. Done means the third While Controller executes its sampler when the condition remains true.
