Subject [PRE-SUMMARY] <xsp-session:getxml>
Date Fri, 27 Sep 2002 03:29:38 GMT
Finally I can said:

IT WORKS!

Please tell me to whom I need to send my 2 cents (4 days and almost his nights 
of work).

I modified the files:

XSPSessionHelper.java
Session.xsl

And I can said that now it works, again.

Many thanks to Carsten and Gritsenko. They give me tips to get into the 
sources and the architecture inside Cocoon to write this new tag that I am 
sure many people will welcome.

Antonio Gallardo.
