I had an incorrect fix for issue2550601. Changed schema to define class patches not patch. Changed commented out patches section in bug.item.html to use patches-1 an not patch-1 as a result of schema changes. The show open Milestones link had a leak of the @group value. If you clicked on show open tasks or show open bugs they group by priority. The url being formed for show open milestones was inheriting the @group if you were on an index page for bugs or milestones. Explicit set the @group to status (which a milestone does have) prevents the @group=priority from being applied to a milestone index page which results in a red error banner stating priority is an invalid param for milestones. ./demo.py -t devel now runs without obvious breakage.

    ''' If the message doesn't have a summary, make one for it.

    if newvalues.has_key('summary') or not newvalues.has_key('content'):
        return

    summary, content = parseContent(newvalues['content'], config=db.config)
    newvalues['summary'] = summary

    # fire before changes are made
