Martin, my problem that example with tr:document and tr:form is not working. i am looked for example how to use tr:fileDownloadActionListener, nothing more. It seemed were simply to implement..Other word, I have used this jsp and my question whta is wrong here, why doesnot start file dialog, nothing more. I had not idea to satrt discussion, it seemed very natural, authors might recognize problem. Ok, if it neesd debugging, no problem, I have an other approach. best regards Oleg
