Yes. I think this is the problem.
Struts2 "Stream result type" doesn't refresh page.
Some suggestions?
Thanks

My take on your problem - Your page isn't getting refreshed so the field
errors remain.

Subject: Clear field error on submit
Hello.
This is a Struts 2 example to show the use of custom result type to
download file.
I have in jsp :
- 1 password textfield
- 1 submit button
If I push submit button without insert a password I correctly obtain a
field error "Field required!".
Then If I set "XYZ" password (correct password), I correctly download
"downloadfile.txt" but
field error remain.
Why?
Thanks
