TracHoursRoadmapFilter is not working on BitNami Trac Stack

[Jader Meros]

After installing TracHoursPlugin on my BitNami Trac Stack server all functionality from trachours plugin is available except for TracHoursRoadmapFilter (although enabled on the plugins page).

Package Version

• Trac 1.0
• Babel 0.9.6
• Docutils 0.5
• Genshi 0.6 (without speedups)
• mod_wsgi 3.3 (WSGIProcessGroup WSGIApplicationGroup %{GLOBAL})
• Pygments 1.4
• pysqlite 2.6.3
• Python 2.7.3 (default, Sep 3 2012, 09:11:12) [GCC 3.2.3 20030502 (Red Hat Linux 3.2.3-56)]
• setuptools 0.6c11
• SQLite 3.7.10
• Subversion 1.7.5 (r1336830)
• jQuery 1.7.2

Installed Plugins

• ComponentDependencyPlugin 0.1 (rev 13350)
• TicketSidebarProvider 0.0 (rev 13350)
• TracAccountManager 0.3.2
• TracHoursPlugin 0.6.0dev (rev 13350)

When accessing the roadmap or a specific milestone page, no information regarding the estimated and total hours is displayed. Looking on the Trac logs no error or warning messages are displayed. The only entries about TracHours are:

Most likely the XPath expressions need to be adjusted to account for changes in roadmap.html and milestone_view.html in Trac 1.0. The estimated and total hours are added in the ITemplateStreamFilter implementation​.

Replying to rjollos:

I took a look on the ITemplateStreamFilter implementation and found where the issue was. Below the diff from web_ui.py with the change I made to make it work again. Please feel free to use it to fix the bug and close the ticket.

In 13396:

Estimated and total hours were not displaying on the roadmap and milestones in Trac 1.0 and later. Fixes #11275.
