Yesterday evening I noticed java.io.InvalidObjectException stopped being thrown. I don't know why but I hope it is related to switching from eclipse to intellij & not due to gae. (I also learned facelets is built into jsf2 so a separate jar isn't required.)
I have two new problems which only happen on live gae--not dev gae: 1) I'm testing jsf-basics.zip on http://www.coreservlets.com/JSF-Tutorial/jsf2/code/. * open bank-lookup.jsf * fill in form * click [Show Current Balance] * the correct jsf page is displayed * click chrome's Back * javax.faces.application.ViewExpiredException is thrown (whether using client or server state saving): org.apache.myfaces.shared_impl.util.StateUtils reconstruct: View State cannot be reconstructed javax.faces.FacesException: javax.faces.application.ViewExpiredException at org.apache.myfaces.shared_impl.util.StateUtils.decrypt(StateUtils.java: 490) at org.apache.myfaces.shared_impl.util.StateUtils.reconstruct(StateUtils.java: 378) at org.apache.myfaces.renderkit.html.HtmlResponseStateManager.getSavedState(Ht mlResponseStateManager.java: 213) at org.apache.myfaces.renderkit.html.HtmlResponseStateManager.getState(HtmlRes ponseStateManager.java: 160) at org.apache.myfaces.view.facelets.DefaultFaceletsStateManagementStrategy.res toreView (DefaultFaceletsStateManagementStrategy.java: 140) at org.apache.myfaces.application.jsp.JspStateManagerImpl.restoreView(JspState ManagerImpl.java: 388) at org.apache.myfaces.shared_impl.view.ViewDeclarationLanguageBase.restoreView (ViewDeclarationLanguageBase.java: 106) at org.apache.myfaces.view.facelets.FaceletViewDeclarationLanguage.restoreView (FaceletViewDeclarationLanguage.java: 1277) .... This doesn't happen if I submit the form with errors, fix them, & click [Show Current Balance] button: * open bank-lookup.jsf * click [Show Current Balance] button * validation errors are shown (post back) * correct errors * click [Show Current Balance] button * click Back button 2) A simple use of <f:ajax> doesn't update: <h:selectOneMenu id="menu" value="#{bankingBean.customerId}"> <f:ajax event="change" execute="@this" render="register"/> <f:selectItems value="#{bankingBean.customerIds}"/> </h:selectOneMenu> <h:outputText id="register" value="#{bankingBean.customerId}"/> On Thu, Oct 21, 2010 at 9:32 PM, ken keller <[email protected]> wrote: > I'm a JSF2/myfaces rookie.
