[Denis Shestov]

Hi! 

Case: get how many change due date in issues project.

I think, first time i must create sil script. 

But i can't get history for field DueDate. 

i tried this options: 

JFieldChange latestChange //1st var.

fieldHistory //2st var.

but result return = EMPTY

if i try lastChange - I get the actual value of the last change. where the name of the field is displayed duedate 

Running script JQLDone. Program returned: odmin|2018-06-28 10:36:53|duedate|2018-06-13|2018-06-15

Help pls

The colleague helped: 
the documentation indicates the use  of JFieldChanges [] : https://confluence.cprime.io/display/SIL/getFieldChanges 

but actually: 

string k="TEST-5";
string[] field_history;
field_history = getFieldChanges(k, "duedate");
runnerLog(field_history);
