How to fix stacktrace with: 'Session is required'
I'm sending this short summary, which contains the dumb answer to a dumb question, so that: - Other dummies know what to do when they make the same dumb mistake. - One day when the trouble shooting guide is witten, this can be part of it.

That is an incorrect assumption. The session must be explicitly created. > The session documentation doesn't say very much on this issue. Also wrong. Smacks self and repeats 'RTMF' 100 times! Look at: http://localhost:8080/cocoon/documents/userdocs/actions/session-action.html Where it states that you need to use the session action to create a session. Change the pipeline as follows: > <!-- Form Handler --> > > <map:match pattern="*-form.html"> > <map:generate type="serverpages" src="xsp/{1}-form.xsp"/> <!-- The next line causes the session to be created --> <map:act type="session"/> > <map:transform type="session"/> > <map:transform src="xsp/form2html.xslt"/> > <map:transform src="xsp/simple-page2html.xsl"/> > <map:serialize/> > </map:match> --------------------------------------------------------------------- Please check that your question has not already been answered in the FAQ before posting. <http://xml.apache.org/cocoon/faq/index.html> To unsubscribe, e-mail: <[EMAIL PROTECTED]> For additional commands, e-mail: <[EMAIL PROTECTED]>
