No graph when no components are defined

[forum-mail@…]

If there are no components defined there will be no burndown visible. That's very surprising and difficult to figure out without looking at the code. Would be nice to have a fix for that.

Code (burndown.py), problem marked by XXX:

   def update_burndown_data(self):
        db = self.env.get_db_cnx()
        cursor = db.cursor()

        # today's date
        today = format_date(int(time.time()))

        milestones = dbhelper.get_milestones(db)
        components = dbhelper.get_components(db)

        for mile in milestones:
            if mile['started'] and not mile['completed']: # milestone started, but not completed
XXX PROBLEM>>>  for comp in components: XXXXX HERE: WHAT IF NO COMPONENTS?? XXXXX
                    sqlSelect =     "SELECT est.value AS estimate, ts.value AS spent "\
                                        "FROM ticket t "\

Thanks!
