Hi,
I've tried to adding attribute scope="session" at the taglib util:counter in
the xsl/lib-page.xml example.
But there is an exception:
java.lang.NullPointerException
at
org.apache.cocoon.processor.xsp.XSPUtil.getSessionCount(XSPUtil.java:450)
at
_E_._jakarta_tomcat_3_2_1._webapps._cocoon._samples._xsp._lib_page.populateD

I try to adding at the xsp/page.xml the method:
private synchronized int sessionCount(HttpSession session) { Integer
integer = (Integer) session.getValue("util.counter"); if (integer ==
null) { integer = new Integer(0); } int cnt = integer.intValue()
+ 1; session.putValue("util.counter", new Integer(cnt)); return
nt; }
and this row that call the method above:
<p>I've been requested for session
<xsp:expr>sessionCount(request.getSession(true))</xsp:expr>
times.</p>
If I call before xsp/page.xml, after also the xsp/lib-page.xml works fine.
Is there bug in the logic-sheet or haven't I understood like works the
taglibs?
Thanks in advance.
Pier Paolo.

Corey,
thank you, it works fine, but I was not know that was create-session="true" exist.
Where I can find doc about all built-in taglibs and about their attributes?
Or better, do you know where I can search about it?
Very thanks?
Pier Paolo.

hi,
Have you setup a session using create-session=true or
request.getSession(true)?
for example
1)
<xsp:page
language="java" create-session="true"
xmlns:session="http://www.apache.org/1999/XSP/Session"
xmlns:xsp="http://www.apache.org/1999/XSP/Core"
>
<Your stuff/>
</xsp:page>
