I had a related problem. An Ajax form submit stopped working after the
page returned a StreamResponse. Manually refreshing the page fixed it,
which provided the clue to a better fix. (Aided by this list -- there were
a couple of posts on 9/4 and 9/24 about it... maybe this is corrected in a
later version of Tapestry.)
Here's the fix I added to my StreamReponse class. It works for me but
you'll see the limitations.
public class MyStreamResponse implements StreamResponse {
public void prepareResponse(Response response) {
response.setHeader("Expires", "0");
//... other header settings...
// Tell the browser to refresh soon after the stream is delivered,
// with this Refresh header. It isn't a perfect fix because it
doesn't take effect
// if the user clicks Cancel on the file-download dialog (if the
user doesn't allow
// automatic file opening).
//
// The refresh will cause the user's form inputs to be lost.
// Hence I've made the form values page-persistent in pages using
this.
* response.setHeader("Refresh", "1");*
//...
}
}
