ActiveRecord::StaleObjectError exception generated on duplicate issues
As documented in the forum...
I have three issues eg. A,B and C that are all reporting the same bug.
Issues A and B were entered first and related as duplicates of each other.
Despite being documented in the FAQ, it was non-intuitive that changing the state of one of these also changed the state of it's duplicate.
There might have been intervening state changes to any of the three issues.
Later, C was added and related as a duplicate of both A and B.
Attempting to change the state of this third duplicate (triplicate?) caused a StaleObject exception.
