docs: FIXME are we going to use this function function getConflictByGuid(conflict, guid) { var relids, i, result; if (conflict.guid === guid) { return conflict; } relids = getDiffChildrenRelids(conflict); for (i = 0; i < relids.length; i++) { result = getConflictByGuid(conflict[relids[i]], guid); if (result) { return result; } } return null; } now we try a different approach, which maybe more simple
