Yet another small trick to make your user's life bearable: when developers close an issue with resolution duplicate, you should normally copy the watchers and the reporter to the original issue.you should normally copy the watchers and the reporter to the original issue.
Solution
Writing the code
This is done in SIL™ in the following way:
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 the post function on the transition Resolve issue and that's all.
