UndefinedError: "interval_hrefs" not defined

[kochhe@…]

After installing the ExtendedVersionPlugin on trac 0.11.1, I get the error message UndefinedError: "interval_hrefs" not defined when I click on a specific version name on the versions roadmap or the normal roadmap page.

This happens after

• installing the plugin
• upgrading the environment
• creating a new version
• assigning some milestones (one or more) to this new version

I installed the plugin in the usual way for a single trac instance by creating an egg and dropping it in the plugins directory.

More detailed error information:

Python Traceback

trac.ini contains the following information:

[extended_version]
navigation_item = version
roadmap_navigation = true

That's odd.

Can you provide a complete stack trace?

I can't find any reason why the intervals wouldn't be defined. I know this works in later versions of Trac (at least 0.11.5 and 0.11.6). Can you update Trac?

[kochhe@…]

Ok, I'll try to update trac to 0.11.5 or above and see if the problem persists. Maybe it's just an out-dated trac installation.

kochhe,

did upgrading to 0.11.5 or above fix your problem? i'm also running 0.11.1 and seeing this problem, but my vendor doesn't have anything newer, so i'm hesitant to upgrade.

Same situation here - 0.11.1 officially supported by vendor and upgrading to something newer but usupported is difficult because of the company's security policy.

Moving to 0.11.7 solved the problem.

There is no interval_hrefs defined in version.py:_render_view, they are only defined for milestone, not for versions.

In 0.11.1, the progress_bar macro requires a interval_href, not in latter 0.11: ​http://trac.edgewall.org/changeset/7602/branches/0.11-stable/trac/templates/macros.html

providing an interval_hrefs

[Malcolm Studd]

Applied patch from schodet. Still works for me with 0.11.7, and should for those with earlier 0.11 releases.
