Uploadwindow hangs

[kamuffe]

Hi.

My Setup: vaadin 7.3.1 multifileupload 1.8 push disabled Valo Theme

I upload a file and the window appears on the screen. After round about 1% it hangs. I can close it or abort the upload. But the file is uploaded to the server. I tested with Chrome and FF 24.8.1

Regards, Christoph

Same issue exists for me with 1.9 version. A file of size 800MB is uploaded, upload window hangs around %1, however it accomplishes uploading, except we do not see status of upload on the screen due to freeze.

Issue still exists in 1.9 with vaadin 7.3.8.

I can reproduce this issue with 1.9 and vaadin 7.4.5. It also happens with smaller files (<1MB)

Could you provide a sample code where the problem can be reproduced? Still exists in 1.10?

Hi.

This Issue still exists with vaadin 7.6.3 and plugin 1.10. Further more it does not show up automatically and shows up and updates its contents only if I click somewhere else in the UI.

TestUI:

package sampleapp;

public class UploadTestUI extends UI {

private VerticalLayout mainLayout;

@Override

    mainLayout = new VerticalLayout();
    mainLayout.setSizeFull();
    mainLayout.setMargin(true);
    setContent(mainLayout);

    UploadStateWindow win = new UploadStateWindow();
    win.setOverallProgressVisible(true);
    win.setCancelButtonCaption("Abbrechen");

    MultiFileUpload upload = new MultiFileUpload(new MyUploadFinishedHandler(), win);
    upload.addStyleName("uploadstyle");
    upload.setPanelCaption("aktueller upload ...");
    upload.getSmartUpload().setUploadButtonCaptions("Datei hochladen", "Dateien hochladen");

    mainLayout.addComponent(upload);

        }
        catch (FileNotFoundException ex)
        {
        }
        catch (IOException e)
        {
        }
    }

};

There are also these errors in console log: Feb 22, 2016 4:01:49 PM com.vaadin.server.ConnectorResourceHandler error WARNUNG: Ignoring connector request for no-existent connector 18 in root 0 Feb 22, 2016 4:01:50 PM com.vaadin.server.ConnectorResourceHandler error WARNUNG: Ignoring connector request for no-existent connector 21 in root 0

Have the same errors on upload after call of handle Files.

In case of push disabled and poll interval >> 1000, you should set poll interval in UploadStartedHandler to 1000 to refresh the window correctly and set back to the original value in UploadFinishedHandler.

UploadStartedHandler

Can you give a more specific example?
