Infinite retries to upload the file after its finished

GoogleCodeExporter commented 8 years ago

What steps will reproduce the problem?
1. Create a custom Modal
2. Append a Well to the custom Modal
3. Append a SingleUploader to the Well
4. Add a OnFinishUploaderHandler to the SingleUploader
5. Upload a file
6. On Success in the OnFinishUploaderHandler close the Modal
7. The OnFinishUploaderHandler is called in an infinite loop until the modal is 
closed. Additionally I get the exception below.

What is the expected output? What do you see instead?
The expected behaviour would be the file is uploaded once.

What version of the product are you using? On what operating system?
gwtupload1.0.3 gwt-2.6.1 java7

Please provide any additional information below.

Original issue reported on code.google.com by russ.seb...@googlemail.com on 16 Jan 2015 at 10:16

GoogleCodeExporter commented 8 years ago

I followed your "getting started" example and used the custom upload servlet.

GoogleCodeExporter commented 8 years ago

The exception is thrown in Upload.java line 443 because the serverRawResponse 
is "" (empty). Maybe you could add a check like:

if (!serverRawResponse.isEmpty()) {

But that shouldnt be the problem...

Why does it call the OnFinishUploaderHandler several times?

seems to be same problem like issue 199

Seems to be a problem of the FireFox v24 ESR (needed for GWT debug plugin)

I've got exactly the same issue , tested on version of FF 24 and 35 with the 
sample app. Works on Chrome.

It loops indefinitely on server side and client side after file is uploaded 
when using the singleUploadSample and using browser input.

The deployed sample app seems affected too (see screenshot attached)

I missed to provide these informations:

I've got the issue on release 1.0.3 , while I hadn't the issue on snapshot 
1.0.2-20140710.123924-2

Tested on GWT 2.6.1 and 2.7.0

I think the issue is related to this commit : 
https://github.com/manolo/gwtupload/commit/3f788b9bce74789a72b6da6f29149e120cd14
6fd

when I revert it and try again, it works now on FF, unfortunatly, you will get 
back the issue on Chrome.

Hi guys,

Do you have any updates on this issue?

Tested on 2.7.0 in FF.

I'm unable to reproduce this issue, maybe I don't understand well.
I've tried the example in the web and don't see the issue, could someone 
describe an step by step, or provide an example?

Original comment by manuel.carrasco.m on 9 Feb 2015 at 7:06

Changed state: Accepted

GoogleCodeExporter commented 8 years ago

I've reproduced it that way:

Use Firefox (I use version 33 and 24)

go to 
http://gwtupload.alcala.org/gupld/gwtuploadsample.SingleUploadSample/SingleUploa
dSample.html

Click on Choose a file (I tried with the third and fourth uploader)

upload with browser input a small file (for example image).

you can see in the bottom panel that file is infinitely republished.

My bet is that this code is triggering onload event continuously, but I'm 
really not sure.

      var i = $doc.querySelector('iframe[name="' + name + '"]');
      if (i) {
        var o = i.onload;
        i.onload = undefined;
        var p = i.parentElement;
        p.removeChild(i);
        p.appendChild(i);
        i.onload = o;
      }

After upgrading to 1.0.3 (which I needed after bumping up to GWT 2.7), I 
experienced the infinite loop in non-WebKit browsers (i.e., FF26, FF37Dev, 
IE8-11).  My test file would upload successfully on the first attempt and the 
browser would receive back the upload location url, but then the uploader would 
continue trying to post to my servlet over and over with a null file path.  
Using florian's advice 
(https://code.google.com/p/gwtupload/issues/detail?id=209#c7), I commented out 
the call to reatachIframe(String) at Uploader.java:1317 and this problem went 
away.  I have a single-page GWTP app and have never experienced

hello,
i am experiencing the same problem using gwtupload1.0.3 gwt-2.7 java version 
"1.7.0_45"
Note that i only get this when i use gwtupload in SmartGwt5.0 application. it 
worked fine when tested in a pure GWT only app
its a blocking bug for us. any idea how to get around this?
thanks

Could it be related to the comment in "onFrameLoadImpl()" (row 642) in this 
class in GWT?
https://gwt.googlesource.com/gwt/+/2.7.0/user/src/com/google/gwt/user/client/ui/
FormPanel.java

I have been debugging this issue and that is where the SubmitCompleteEvent with 
an empty result string is dispatched in my code. 

This is the GWT commit for the comment 
https://code.google.com/p/google-web-toolkit/source/detail?r=1124

Any good workaround available yet?

One more thing. I can reproduce it on all uploaders on this page.
http://gwtupload.alcala.org/gupld/gwtuploadsample.SingleUploadSample/SingleUploa
dSample.html

But not when using the drop areas. Only when clicking on the "Choose a 
file"/"Browse" buttons. 

(Using Firefox 24)

PS. Google will be shutting down code.google.com this year, i guess this is 
your github page https://github.com/manolo/gwtupload and this is the same issue 
there https://github.com/manolo/gwtupload/issues/11
The discussion should continue over there.
