view-scope

I have switched to javax.enterprise.context.SessionScoped to javax.faces.view.ViewScoped Upgraded faces 2.1 to 2.2 to be able to use ViewScoped with my CDI injections. After I switched to ViewScoped I have started getting this error and I can't figure out why! Do you think there is something wrong here? Glassfish 3.1.2, Primefaces 3.4.2, JSF 2.2 org.jboss.weld.context.ContextNotActiveException: WELD-001303 No active contexts for scope type javax.faces.view.ViewScoped The button opens the page: The jsf page; <h:form enctype="multipart/form-data"> <p:fieldset legend="Create new feed" toggleable=

My question is related to this one (and probably others): @PreDestroy never called on @ViewScoped As stated there, there's no trivial solution to either have view-scoped beans destroyed upon navigation and the same seems to hold true for when the session expires. What would a non-trivial approach to release (calling the @PreDestroy method) JSF view-scoped beans look like, or more specifically as soon as the session expires? I'm using Java EE 6 and Mojarra 2.1.x on GlassFish 3.1.2. Create a @SessionScoped bean to hold the resources (in some collection/array?) and inject it in the @ViewScoped

I'm using Myfaces 2.2 with Client-side state saving . I see that the ViewScoped beans & data stored in viewmap is lost after the user session is destroyed. I came to know, not sure if it is correct, that this is the expected behavior but then what's the way to avoid view expired exceptions after session destroy? My problem is that I destroy the user session pretty quickly after some inactivity period(like after 20 minutes) but I want the viewscope data to survive even after that(when using client saving) so that when the user comes back after session destroy, he doesn't need to do a page

There is an error each time a button calls an action from the backing-bean. Only applies to beans with a view scope and I haven't found a way to fix it without regression over other modules in the code.

From what I understand, ViewScoped beans only get destroyed when one of the following take place: 1) JSF sends a POST request to another page with something like a <h:commandLink...> 2) The number of open beans exceeds the maximum threshold setting (default of 15) 3) The user's session expires Here is my confusion: Does #1 mean that if a user navigates away from the page with a GET request, the bean will stay open, even if eventually a JSF POST happens in the same browser tab on another page? Or will all active @ViewScoped instances for that browser tab be destroyed once a JSF POST is sent

In my JSF page this works: ${requestScope.put('test', 'data')} ${requestScope.get('test')} This causes exception: ${viewScope.put('test', 'data')} ${viewScope.get('test')} Exception: java.lang.NullPointerException javax.el.BeanELResolver.invoke(BeanELResolver.java:159) javax.el.CompositeELResolver.invoke(CompositeELResolver.java:84) org.apache.el.parser.AstValue.getValue(AstValue.java:157) org.apache.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:184) com.sun.faces.facelets.el.ELText$ELTextVariable.writeText(ELText.java:238) com.sun.faces.facelets.el.ELText$ELTextComposite.writeText
