Hello.
While converting a SnoopServet to Jboss 7.1.1.Final and Richfaces 4.2.2.Final, I encountered an unexpected exception when my servlet iterated over an enumeration of servlet context attributes:
{code}
ServletContext context = getServletContext();
out.println("Context attributes:");
e = context.getAttributeNames();
while (e.hasMoreElements()) {
String key = (String)e.nextElement();
Object value = context.getAttribute(key);
try {
out.println(" " + key + " = " + value );
}
catch (NullPointerException npe) {
out.println(" " + key + " = [NullPointerException]" );
};{code}
The attributes are all correctly listed on the HTML output except for context attribute "richSkin". Prior to implementaing the try/catch for a NullPointerException that attribute always threw a NullPointerException:
{code} java.lang.NullPointerException org.richfaces.skin.SkinFactoryImpl.getSkin(SkinFactoryImpl.java:57) org.richfaces.skin.SkinBean.getSkin(SkinBean.java:85) org.richfaces.skin.SkinBean.toString(SkinBean.java:95) java.lang.String.valueOf(String.java:2826) java.lang.StringBuilder.append(StringBuilder.java:115) ca.gerrymatte.tests.SnoopServlet.doGet(SnoopServlet.java:72) javax.servlet.http.HttpServlet.service(HttpServlet.java:734) javax.servlet.http.HttpServlet.service(HttpServlet.java:847) org.jboss.weld.servlet.ConversationPropagationFilter.doFilter(ConversationPropagationFilter.java:62) {code}
The richSkin attribute was not something that I defined in my application ...... I assume it is created by richFaces itself. If so, richFaces should not create a context attribute that triggers a NullPointerException when one attempts to retrieve it.
This error was also reported on the internet at [http://code.google.com/p/psi-probe/issues/detail?id=229]
