> Key: RF-12352
> URL: https://issues.jboss.org/browse/RF-12352
> Project: RichFaces
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Components: component-input
> Affects Versions: 4.0.0.Final
> Environment: Mojarra 2.1.7, Jetty or JBoss 5.1
> Reporter: Tomasz Kurpios
> Fix For: 4-Tracking
>
>
> In Mojarra 2.1.7 the value of first invocation of
> FacesContextImpl.isPostback() is cached as a request attribute. It checks for
> the existence of javax.faces.ViewState parameter. If we are processing
> MultipartRequest and FacesContextImpl.isPostback() is executed before
> FacesContextImpl.getPartialViewContext(), FileUploadPartialViewContextFactory
> hasn't had yet chance to parse this MultipartRequest's parameters, so
> FacesContextImpl.isPostback() returns (and caches) false. Therefore no
> processing (decodes, validations, updates) happens and as a consequence
> properly registered FileUploadListener is not executed.
> The only reason why it normally works is because completely unrelated method,
> com.sun.faces.context.ExceptionHandlerFactoryImpl.getExceptionHandler(),
> *happens to* call FacesContext.getPartialViewContext() and this happens
> during creation of FacesContext instance.
> In my environment, I used my custom ExceptionHandlerFactory (registered in
> faces-config.xml) which did not call FacesContext.getPartialViewContext() and
> the problem appeared, because FacesContext.isPostback() was called first.
> This means that currently FileUploadPartialViewContextFactory is very tightly
> coupled to FacesContextImpl, which in my opinion should be fixed.
