"Could not find component for role" after upgrading to 0.8

Hello,

I wanted to be able to use Forrest 0.8 to successfully build a site
that worked with Forrest 0.7.

I started this project last week, so I may have forgotten some of the
things I did.

I changed $FORREST_HOME to point to Forrest 0.8 instead of 0.7. "type
forrest" in bash confirms that "forrest" runs Forrest 0.8.

I then tried to follow the directions in
http://forrest.apache.org/docs_0_80/upgrading_08.html . I copied
locationmap.xml . I did not know what to do about the "Forrest
configuration simplification" step. I ran "forrest clean-work".

When I run "forrest" I get this line after the Cocoon header block:

X [0] linkmap.html BROKEN: Could
not find component for role:
[org.apache.cocoon.components.modules.input.InputModule/project]
(Key='org.apache.cocoon.components.modules.input.InputModule/project')

The build is aborted after this failure.

What can I do?

Thanks,
Brolin

PS: See my previous posts for my system configuration.

That error sounds like you need to follow the upgrade
instructions and do the bit that you missed.

Do you have a "project sitemap" or your own "plugin"?

If so then follow the "Forrest configuration simplification"
step. See the last item which refers to a properties module
called "project" which is what your error message says.

Is this a skins-based site, or is it using an early
version of the whiteboard Dispatcher in development?

I solved the problem.

I did not know what to do for the "Forrest configuration
simplification" step because I could not find any text to replace in
site.xml .

I did a recursive grep in my Forrest "src" directory and found that I
had to edit sitemap.xmap instead of site.xml . Perhaps the upgrade
instructions could be more clear about which files need to be edited?

The upgrade instructions do not mention the site.xml

It sounds like you are getting confused:

The "Cocoon Sitemaps" i.e. any file ending with *.xmap
is the system to enable Cocoon to know how to process
different types of input and output.

The site.xml is the menu navigation and linking
configuration file.

I added another section at the bottom to explain
that you can remove a project sitemap.xmap if you
are not using it.
http://forrest.apache.org/docs_0_80/upgrading_08.html#project-sitemap

I also showed the error message at
http://forrest.apache.org/docs_0_80/upgrading_08.html#modules
which should help with FAQ searching.

Hope that helps others to avoid this mishap.

This is an understandable mistake, in many other environments sitemap
means a map of the site, which is what site.xml can be considered to
be.

We should remember this and try and make the distinction clear in user
level docs.

Thank you for your efforts.

I would like to suggest that a new paragraph similar to the following
be added at the bottom of
http://forrest.apache.org/docs_0_80/upgrading_08.html#modules

"If you are receiving this error message, check that you are editing
the Cocoon Sitemap files (*.xmap) instead of site.xml (the menu
navigation and linking configuration file)."

Thanks. I took a different approach and added some entries
to the glossary and referred to that.

That sounds like a better solution than my suggestion, because your
approach minimises duplication of definitions. Now that I think about
it, my suggestion was inviting duplication of definitions.

Thanks,
