Re: Clearing form errors problem
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);*
//...
}
}

A technique would be return the page, then re-direct the user to a
different page / event link which returns the CSV.
It's also discussed in this thread:

Re: Clearing form errors problem
Hi,
I'm a bit confused...
StreamResponse onSuccess() {
form.clearErrors();
...
}
OnSuccess() is only called when there are no errors in the form, so
what are you trying to clear, and how do you know it's not working?
Steve.

Re: Clearing form errors problem
Hi,
I'm trying to clear errors which happened before - so eg. user inserted
invalid date = pressed Download = error
void onValidateForm() {
if(dateTo == null) {
form.recordError(Please insert valid date to!);
return;
}
}
but after that user corrected the date and pressed Download = the file is
downloading but the error Please insert valid date to! is still in the
form.

It's still there because you cleared the form errors server-side, not
client-side. As you're returning a StreamResponse, no changes are done in
the page DOM. In addition, as Steve said, onSuccess() will never be
invoked with validation errors.

Thank you for your response.

Clearing form errors problem
I'm using tapestry 5.0 and I have a problem with clearing form errors. When Download button is pressed, and all form validation is OK I need to download a file. In order to do this in the onSuccess() method I get the HttpServletResponse object, set it's character encoding, content type etc. and after that I use its PrintWriter to generate CSV file (I'm using open CSV Library and it needs Writer object to generate csv). But when there where errors in the form, after pressing Download button they are not clearing (even after form.clearErrors() - because I used PrintWriter and HttpServletResponse and changed their content). Please can somebody help and tell how to clear these errors ? Thanks. -- View this message in context: http://tapestry.1045711.n5.nabble.com/Clearing-form-errors-problem-tp4971307p4971307.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
