[ https://issues.jboss.org/browse/RF-13323?page=com.atlassian.jira.plugin.s... ] Jiří Štefek commented on RF-13323: ---------------------------------- I tried this by changing the scope of the _FileUploadBean_ with the latest RF4 showcase on AS 7.1 and EAP 6.1 and uploading the same picture for multiple times. I have noticed, that when the scope was @ViewScoped: * uploaded image preview didn't show, * and encountered an error on the server side: {code} ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/showcase].[Faces Servlet]] (http--127.0.0.1-8080-23) Servlet.service() for servlet Faces Servlet threw exception:

can see on the images I've appended here. On the images you can also see that: * 2 request were made (bottom left), * scope of the bean (bottom right), * the updated list (top right) (with or without the image preview). [~bleathem]: there is a problem, but it seems (from the stacktrace) that the bug is in MediaOutput(?) and is connected with Showcase sample not the FileUpload component itself. In this case I can not reproduce the bug. -- This message is automatically generated by JIRA.
