hello Martin,
now I want only determine is next fragment of code appropriate or not:
if no, what I have change to fire download dialog?
<tr:document>
<tr:commandButton text="Download file">
<tr:fileDownloadActionListener
filename="#{downloadBean.fileName}"
contentType="#{downloadBean.contentType}"
method="#{downloadBean.sayHello}"/>
</tr:commandButton>
</tr:document>
inside Firefox -> Tools -> Error Console I see this message;
Error: _checkLoad is not defined
Source File: http://localhost:8080/TrinidadUpload/faces/download.jsp
Line: 1
it is not so informative to debug...
regards
