I am using Netbeans 7.01 and GlassFish. I downloaded PrimeFaces 3.2 and added it to the library. I followed the FileUpload example in http://www.primefaces.org/showcase/ui/fileUploadSimple.jsf. It gives a warning and the holds the functioning of p:fileUpload. I inserted a p:commandButton, but it also seems to be the same. I inserted h:commandButton and it functions as expected with same back bean method. But <p:spinner /> and p:growl are functioning as expected.
