I have noticed similar problems.   For me, hitting the "refresh" button 
once (and sometimes twice) does the
trick.    I am using Cocoon2 beta2 with Tomcat 4.0 beta 7 on Red Hat 
Linux 7.1  with plenty RAM/disk/etc.
I did notice something very interesting yesterday.   I normally start up 
postgresql and use it for my database
(just for the cocoon "personnel" example so far... :-)    But yesterday 
I did not start up postgresql and did not
observe the problem.  All my pages came up right away, fully populated!

Questions:  are you using a database?  Does this behavior occur 
regularly? Intermittently?    Which version of
Tomcat are you using?
