I can't get all worked up about a single string in
session for guests who will only use it if they hit a
page where they need to log in, and if they're logging
in, they're not guests anymore!

While I agree the OGNL docs need some rework:

http://struts.apache.org/2.x/docs/ognl.html

does say "Along with the value stack, the framework
places other objects in the ActionContext, including
Maps representing the application, session, and
request contexts."

Could be clearer, especially for those that don't know
the framework, but it's sorta there, and it's also in
the FAQ:

http://struts.apache.org/2.x/docs/what-are-the-default-variables-in-the-value-stack.html

http://struts.apache.org/2.x/docs/ognl-basics.html
actually mentions 'parameters' down at the bottom, and
specifically states that 'parameters' is for
request.getParameter, 'request' is for
request.getAttribute, etc.

That's a config-file issue, not OGNL, and actually is
addressed in the FAQs, but someone or myself will add
a note to the results configuration page (I think that
makes the most sense?)

http://struts.apache.org/2.x/docs/parameters-in-configuration-results.html

Brain's too small :/

A lot of the issues with the documentation isn't so
much that the information isn't there, but that it's
somewhat difficult find at times.

...and sometimes you are forced to read to the bottom
of the page ;)
