[xwiki-users] XE 8.2.1 NullPointerException in Create action

Hi everybody, I've just got running a fresh new install of 8.2.1 in a Wildfly instance (9.0.x) with datasource and PostgreSQL. No problems until there, and nothing special in config settings other than the default ones. However, as I try to create a new page (child or whatever) clicking on the "+" in any place, XE fires a NullPointerException. Here's the extract of the Stack Trace: Error number 4001 in 4: Error while evaluating velocity template createinline.vm com.xpn.xwiki.XWikiException: Error number 4001 in 4: Error while evaluating velocity template createinline.vm ... Caused by: org.xwiki.velocity.XWikiVelocityException: Failed to evaluate content with id [/templates/create.vm] ... Caused by: org.apache.velocity.exception.MethodInvocationException: Invocation of method 'getParameter' in class com.xpn.xwiki.web.XWikiServletRequest threw exception java.lang.NullPointerException at 284:/templates/create.vm[line 90, column 31] ... Caused by: java.lang.NullPointerException Am I missing something in configs? Regards, RAMON GOMES BRANDÃO
