Hey guys, while working on new showcase, current stage can be seen here (https://github.com/richfaces/richfaces/tree/RF-12901-showcase/examples/bo...), I have come across these two issues, I was not able to solve by now 1. the components are not able to process ajax request for instance list component, tooltip component when I inspect the request in Chrome the response is {{code}}class java.lang.NullPointerException{{/code}}, there is no stacktrace on console I think it is probably related to template used, because when I switch https://github.com/Lukindo/richfaces/blob/RF-12901-showcase/examples/boot... to demo.xthml it works correctly. 2. when showcase is deployed to wildfly, and component page is displayed, for instance http://localhost:8080/bootstrap-showcase/component/chart/index.jsf taglibReader  throws an exception however, the showcase works ok on jboss 7.1.1 {{code}}
