Seam pdf problems
Hi,
I am generating a pdf document and everything seems to work correctly until anyone tries to log in (logging in succesfully or not doesn't make a difference). From that moment I get the following error:
11:39:54,824 ERROR [lifecycle] JSF1054: (Phase ID: RESTORE_VIEW 1, View ID: ) Exception thrown during phase execution: javax.faces.event.PhaseEvent[source=com.sun.faces.lifecycle.LifecycleImpl@1254e47] 11:39:54,824 WARN [ExceptionFilter] handling uncaught exception javax.servlet.ServletException: java.lang.Object cannot be cast to java.lang.String at javax.faces.webapp.FacesServlet.service(FacesServlet.java:277) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:83) at org.jboss.seam.web.IdentityFilter.doFilter(IdentityFilter.java:40) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:73) at org.jboss.seam.web.ExceptionFilter.doFilter(ExceptionFilter.java:64) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.web.RedirectFilter.doFilter(RedirectFilter.java:45) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:73) at org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:177) at org.ajax4jsf.webapp.BaseFilter.handleRequest(BaseFilter.java:267) at org.ajax4jsf.webapp.BaseFilter.processUploadsAndHandleRequest(BaseFilter.java:380) at org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:507) at org.jboss.seam.web.Ajax4jsfFilter.doFilter(Ajax4jsfFilter.java:56) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.web.LoggingFilter.doFilter(LoggingFilter.java:58) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.web.HotDeployFilter.doFilter(HotDeployFilter.java:53) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.servlet.SeamFilter.doFilter(SeamFilter.java:158) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:182) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:432) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.ClassCastException: java.lang.Object cannot be cast to java.lang.String at org.ajax4jsf.application.AjaxStateManager.restoreLogicalViewId(AjaxStateManager.java:573) at org.ajax4jsf.application.AjaxStateManager.restoreStateFromSession(AjaxStateManager.java:454) at org.ajax4jsf.application.AjaxStateManager.restoreView(AjaxStateManager.java:402) at com.sun.faces.application.ViewHandlerImpl.restoreView(ViewHandlerImpl.java:316) at org.jboss.seam.jsf.SeamViewHandler.restoreView(SeamViewHandler.java:93) at com.sun.facelets.FaceletViewHandler.restoreView(FaceletViewHandler.java:316) at org.ajax4jsf.application.ViewHandlerWrapper.restoreView(ViewHandlerWrapper.java:116) at com.sun.faces.lifecycle.RestoreViewPhase.execute(RestoreViewPhase.java:176) at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:100) at com.sun.faces.lifecycle.RestoreViewPhase.doPhase(RestoreViewPhase.java:104) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:118) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:265) ... 41 more
I am using Seam 2.1.1 and Jboss 4.2.3
I try to generate the document with the following xhtml (this is a simplee version for debugging):
<p:document xmlns:p="http://jboss.com/products/seam/pdf" pageSize="A4" margins="15 15 0 15"> <p:image alignment="left" value="img/c2-logo.png" spacingAfter="5"/> </p:document>

</components>I don't think it is a problem with missing libraries because the pdf gets correctly generated just after the server is launched. I am using a Flex client with flamingo 1.7.1 and this method used to authenticate a user:
public static boolean login(final Identity identity,
final String username,
final String password)
throws StaleSessionException {
try {
//If the user is trying to log in but are already logged in,
//we need to log them out first
if (identity.isLoggedIn()) {
// Calling logout will mark the current session for invalidation,
// so performing a subsequent login is pointless.
identity.logout();
throw new StaleSessionException();
}
final Credentials credentials = identity.getCredentials();
credentials.setUsername(username);
credentials.setPassword(EncryptionUtils.hash(password));
identity.login();
return identity.isLoggedIn();
}
catch (EncryptionException ex) {
return false;
}
}Any help would be much appreciated, thanks in advance.
