Hello,

Downloading with the BufferedContentManager works fine with the t:filedownloadbutton component

But what if there is an error while creating the dynamic content?
If there occurs an error and I return an NULL byte[] or an empty byte[] the user also getso the download successfully message!

Do you have suggestions for me how to handle this issue?

regards,
Michael Schmuck

Hi,

what do you do in case of an error?
What you should do: throw an Error/RuntimeException - which should cause a client side message popup.

Could you check?

Okay, with throwing an RuntimeException I can show the user an default "there was an error" message within the download window.

That should be sufficient for now, but it would be nicer to provide an individual error message.

Thanks!

One additional question to the filedownloadbutton.

Doesn't the filedownloadbutton trigger an roundtrip like the normal buttons?

While providing the download content, I set an other attribute in my bean that indicates that the file was already downloaded.
This is shown after the next flush (e.g. scrolling a table or pressing a button) but not after pressing the download button!

Hi,

It is also my experience that filedownloadbutton does not trigger and roundtrip like normal buttons.

Is there a special reason for that?

Hi,

Again I have stepped in this.
Workaround is to set flush=true for the edited fields.
But I think it would be better that filedownloadbutton triggers and roundtrips, wouldn't it?
