problem that blocks tests with htmlunit

[Alin Dosoniu]

Hi,   I want to write a testcase for my application with HtmlUnit. Everytime when I make a request to first page of the application I get this in log: java.lang.NullPointerException  at org.apache.myfaces.renderkit.html.HtmlRendererUtils.selectContentType(HtmlRendererUtils.java:995)  at org.apache.myfaces.renderkit.html.util.DefaultAddResource.writeResponse(DefaultAddResource.java:786)  at org.apache.myfaces.component.html.util.ExtensionsFilter.doFilter(ExtensionsFilter.java:142)  at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202)  at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173)  at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValvejava:213)  at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValvejava:178)  at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:432)  at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126)  at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105)  at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107)  at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148)  at org.apache.coyote.http11.Http11AprProcessor.process(Http11AprProcessor.java:831)  at org.apache.coyote.http11.Http11AprProtocol$Http11ConnectionHandler.process(Http11AprProtocol.java:652)  at org.apache.tomcat.util.net.AprEndpoint$Worker.run(AprEndpoint.java:1203)  at java.lang.Thread.run(Unknown Source)   Because of this, there is an error 500 in the response, so I cannot go on with my testcase. I modified the HtmlRendererUtils source to test for null and I can access my application from HtmlUnit. So, I replaced this: contentTypeListString = (String)                     context.getExternalContext().getRequestHeaderMap().get("Accept"); with this: if (context != null && context.getExternalContext() != null &&  context.getExternalContext().getRequestHeaderMap() != null) {             contentTypeListString = (String)                     context.getExternalContext().getRequestHeaderMap().get("Accept"); }   It is possible that I have an error in my jsps but I think these tests with null should be also in Myfaces code. If this is a problem in MyFaces, should I create a JIRA issue?   Thanks, Alin.
