The problem persist, but I found out why. I attach a testing sample to
explain it.
At first I have to admit that I had a some misunderstanding
* JSON extractor gives multiples vars as result, not an array
* the foreach loop (it loop trough varname_1..N and not on array)
I was misguided by imprecise and poor article on rest api testing, I
should have read carefully the docs first.
Anyway there is still a problem.
I think that the json component ignore the Match Numbers = -1 when it
match only one
From the docs:
Match Numbers
If the JSON Path query leads to many results, you can choose which
one(s) to extract as Variables:
0 : means random (Default Value)
-1 means extract all results, they will be named as variable name_N
(where N goes from 1 to Number of results
X : means extract the Xth result. If this Xth is greater than
number of matches, then nothing is returned. Default value will be used
When JSON extractor match only one result it return the var name without
the counter number even if Match Numbers = -1
In the example I attached the problem is evident.

Hello,
There are some fixes in nightly build.
Could you try it ?
http://jmeter.apache.org/nightly.html
If issue persists, can you create a demo Test plan using Java Request where
you put the JSON in ResponseData and the JSON-PATH POST PROCESSOR that you
use.
Thank you

I'm having a problem not sure if it is a bug or not.
Making the long story short.
I use jmeter 3.0 and bundled json path extractor with some rest api to
make subsequent calls with foreach.
Lets say we have this scenario
country api -> region api ->city api->shop list
Get the country list and extract the array of country id and pass it to a
foreach get regions list for each country, another call to region api and
exctract the cities from the result
Generally everithing works, I get an array and the foreach works as
expected.
But there are situation where I get only one result, because for instance
there is only one region in the country.
In this case json path extractor do not give an array but a simple string
var. This cause the following foreach to not get executed.
I'm not sure if this is the normal behaviour but this completely broke my
script.
Another strange thinks is that I used the debug sampler to monitor the
script and the array never appear there but it exist since the foreach get
executed, the var appear only when is a string.
Here is a debug example:
idCountryList_1=37
idCountryList_2=38
idCountryList_ALL=37,38
idCountryList_matchNr=2
idR=8
idRegioneList_1=8
idRegioneList_2=12
idRegioneList_3=3
idRegioneList_ALL=8,12,3
idRegioneList_matchNr=3
idCityList=37006
idCityList_ALL=37006
idCityList_matchNr=1
for idCountryList I expect to see as first line something like
idCountryList = [37, 38]
While idCityList appear because is not an array since the json contain
just one result.
In this real example after extracting the city list I have another api
call that do not get executed because idCityList is not an array so the
foreach get jumped.
I hope I've been clear.
Thank for any support
