Problem

Yet another small trick to make your user's life bearable: when When developers close an issue with a resolution duplicate, you should normally copy the watchers and the reporter to the original issue.you should normally want to copy the watchers and the reporter to the original issue.

Solution

Write the code

This is done in SIL™ in Enter the following way:SIL™ code.

string u;
number n=0;
n=size(fieldHistory(key, "Link"));
if (n>0 and resolution=="Duplicate")
{
 string dKey=getElement(fieldHistory(key, "Link"),n - 1); // history
 %dKey%.watchers=addElementIfNotExist(%dKey%.watchers, reporter);
 for (u in watchers)
 {
 %dKey%.watchers=addElementIfNotExist(%dKey%.watchers, u);
 }
}

You just need to put this on Next, add this code to the post function on the transition Resolve issue and that's all transition.
