My problem: When trying to use file upload, the file browser disappears after a short moment before being able to select files. The code worked before I did a series of notable changes (JBOSS 4.2.3->6.0.0 , Fedora 13 to Fedora 15, 32bit to 64bit) There is apparently no exception thrown and no error page displayed. Envrionment: Fedora15 64 bit with Gnome3, Firefox5 and 32bit wersion of flash using nspluginwrapper JBOSS 6.0.0.Final JSF1.2 SEAM 2.2.2.Final Richfaces 3.3.3.Final Code snippet: I suppose that there shouln't be anythong wrong with the code as trying to use the demo on the Excadel website doesn't work either. Does anybody has a clue?
