[xwiki-users] Wiki application templates error

Hi, I'm working with a fresh install of xwiki 5.3 (centos6 + openjdk 1.6 + tomcat6 + mysql). I have create a new subwiki (as a template) but whenever I try to create a new subwiki using this template, i only get a blank wiki, just the standard deploy. I have followed these instructions with no luck: http://extensions.xwiki.org/xwiki/bin/view/Extension/Wiki+Application Just after the subwiki creation (from a template) I get a progress bar indicating that the system is provisioning the wiki. When I click on "Finalize", I'm automatically redirected to the "Distribution Wizard" page telling me that I have to install "XWiki Enterprise UI - Wiki". If I skip the wizard, the wiki is shown as it didn't have any UI. Looking at catalina.out I don't see anything strange. I have also found out that the first created wiki template doesn't show in the "Wiki Template" admin panel. If I create a new template, this new one is shown in "xwiki index" and "xwiki template". If I try to create a new subwiki using this second template the error persist. Anyone with this issue? Regards, Jaume
