Description Vladimir Ryabtsev 2014-03-17 14:20:49 UTC
Created attachment 31394 [details] Demonstration of bug and workaround I use a Jmeter variable for the value of Loop Count field. Loop Controller works correctly until first zero-value iteration counter. When meeting one, Loop Controller does nothin (correct) but after that it becomes broken in current thread group till the end of test: even when Loop Counter becomes non-zero Loop Controller does nothing (incorrect). Run attached test plan and inspect Results Tree. Play with "if (iterCounter == 3)" condition and change "vars.put("num_loops",Integer.toString(0));" to any non-zero value and see that it stops breaking. Bug appears in versions 2.10 and 2.11, and does not appear in version 2.9. WORKAROUND: Put Loop Controller inside If Controller to avoid passing zero values to Loop Counter (this shown in WORKAROUND thread group in attached test plan).
