Static URL generates attribute error (on MySQL)

[Stefan Rungardt]

How to Reproduce

While doing a GET operation on /ticketstats, Trac issued an internal error.

1. I clicked on the Ticket Stats tab and waited until the graphs for 'All milestones' were displayed
2. I changed the value of Milestone from 'All milestones' to a specific milestone and clicked 'Update chart' and waited until the graphs were displayed
3. I copied the Static URL and pasted it to the address field of the browser and pressed Enter

Problem: I get an error message saying "AttributeError: 'list' object has no attribute 'find'"

Remark: The Static URL for 'All milestones' works fine.

Request parameters:

{'content': u'render',
 'end_date': u'12/13/2010',
 'milestone': u'Beauty and the Beast',
 'resolution': u'7',
 'start_date': u'11/01/2010'}

Thanks for the report. Bumping the priority to remind myself to investigate by end of this coming weekend.

#11100 closed a duplicate. The reporter notes in that ticket that the issue only occurs when there is a space in the milestone, and therefore the url just needs to be properly encoded.
