Solved in another way.
Instead of implementing it in a separate page, I 've replaced pagelink with
actionlink and handled it in the same page class, for example :
Object onActionFromExport() {
...
return export();
}
StreamResponse export(){
}
Then the browser asked me to download or open the file :) ..

I did not see them, both were in the junk folder , me too surprised that the
answer was not as fast as you used to :) ..
Tried what you said , changed a working page to export excel instead, and got
the same error message...

You've got 2 replies, are you saying none worked for you ?
Why don't you try to just build another mock page for the same behavior with
minimum tapestry customization efforts. May be your index page and see what
happens. If it works, then you configured something wrong. If it doesn't, then
it probably shouldn't in the first place !
