In case it helps any of you, the Table of Contents macro has an "Absolute URL" option.  If you check this option, then a TOC included in an excerpt will work properly in an Excerpt Include on a different page.

I am using Confluence 6.3 and ran into the issue.  I have a page with a page excerpt that is included in a rollup page.  The excerpt includes lots of links to anchors.  Works fine on the original page, dies just as Carla Gray indicates above.

Because this doesn't work I have to maintain two copies of a set of links.

June 8th is my last day on the project but the next developer will run into the same problem and have to put forth the same duplicate effort.

Issue still present in Confluence 6.9 and 6.3.

I'm using version 5.4.4 of Confluence, and I don't see how this is fixed. The issue discussed in "CONF-15098 excerpt-include doesn't correct links to anchor inside the excerpt" is not resolved.

We are also using excerpt and excerpt include. On the original page, I insert a link to a specific heading on that page (Insert > Link > Advanced. In the link field, enter "#HeadingTitle"). Then, I use the excerpt include macro, and the link doesn't work. I've tried the following to fix it:

• Inserted an anchor on original page. This will not work on the include page.
• Inserted "#HeadingTitle." This will not work on the include page.
• Inserted "Page Name#HeadingTitle." Confluence automatically strips out the current page name and saves it as just "#HeadingTitle." As a result, this does not work on the include page.

Kendziorra. As you have found, that particular case does not work very well although it is a different issue from this one.

An issue already exists in the TOC project although I have added a comment just to clarify your problem case.

Should it work?
I've got a testaccount with confluence on demand, but there is no change?
I tried to add a

to an

and to include this in an other page

Anchor generation in Confluence 4.0 no longer has this problem.
Confirmed fixed for both the include and toc macro cases described here.

In an old version there was an wrong implemented undocumented parameter absoluteUrl=true (for TOC).
see here: https://studio.plugins.atlassian.com/browse/TOC-42 On this site are a patch for the wrong implementation.

May be this param (absoluteUrl=true) is a way to solve this problem. If someone want to use an anchor link included in an other site, he have to set this parameter ???
But needed to implemented !? It's only an idea.

This affects the table of contents macro as well. Recently reported as CONF-21713.

Sorry, it looks like most of the comments and votes here are actually about the

macro, and we have a bunch of duplicate issues resolved against this one.

I'll reopen it and rename the issue so it makes more sense.
