I tried that as well along with many other combinations earlier, nothing seems to works using server Jira V6.4

[Arun_Thundyill_Saseendran]

This is strange. I am using add() on the List<ApplicationUser>. And add() is a method in list. My bad. I think I missed the initialization of list. Silly!

 Can you change 

List<ApplicationUser> users;

 to

List<ApplicationUser> users = new ArrayList<ApplicationUser>();

and try. I currently do not have an instance with me to try. That's why.

Thanks @Arun_Thundyill_Saseendran for responding.

Yup I am using the same, and included the

ApplicationUser package as well. This strange behavior even i am not able to understand, i again just copy pasted your suggested code as well. But no Hope.

I have raised a case with Adaptavist team as well.
Here is the case .. hoping to get solution from either way

[Arun_Thundyill_Saseendran]

I have update the full code as well. The null error for sure was my coding glitch. Please try and let me know.

[vishal goyal]

PERFECT!!!!!!!!.. it worked. Though it overriding the older value every time but its fine i can fix that... Thanks a tonne @Arun_Thundyill_Saseendran.

I think issue was on this part

new ArrayList<ApplicationUser>(); 

[Arun_Thundyill_Saseendran]

Yes. For it to not override, you can just read from it add it to the same list before you update. 

Good to know it helped.

Anytime!
