I am using SmartGWTPower 2.5, GWT 2.3, Firefox 10.0.2., Windows 7 (SmartClient Version: SC_SNAPSHOT-2011-08-02/PowerEdition Deployment (built 2011-08-02)). I have a form which contains 2 binary fields, only the first file has arrived successfully at the server side. Could you please help me solving the problem?
