[opencms-dev] invalid navigation paths in demo project

[weHe @ FreeCreatives]

Hi,

I've followed the demo in the book's chapter one
and created two pages to see the navigational links
created by openCMS (v5beta)....

unfortunaltely, the navigation links for my pages point to
/opencms/export/projects/<file>
instead of
/opencms/opencms/projects/<file>

when I follow them, an error message
"+++
CmsJspTemplate.getContent(/system/modules/default/frametemplates/default):
Static export of JSP not supported! +++"
appears instead of the page,
while the page can be properly views
at the /opencms/opencms/projects/... location
(btw, they're all *.html, no *.jsp files!!)

Any ideas what I'm doing wrong?
Thanks a lot for your help and all the best!
