Jason Correlation

I have Jason response and following JasonPATH syntax $.results[*].case_id will gives me result as follows


Now I want to capture all these value in a correlation parameter. I defined following in my gating script


but this is capturing only first element from the above list 1527689501729638. How I can capture all the above value through and how I can substitute all value on further request ?


Is this forum active for Gatling related questions / query ? I am failing that user needs to wait for long time to get the answer for their question/queries.
