Got unexpected request sequence number

Hi,

I'm in the process of migrating to Orbeon Forms 3.9 RC1.

However, periodically I get an exception with the message "Got unexpected request sequence number" - see the stack trace below. Also, when this happens none of the links (submits/triggers) on the page either don't seem to work and every few seconds more exceptions recur, or clicking on a link then seems to navigate to the wrong page. The only way then to proceed is to manually refresh the page. It seems that the navigation history is going wrong some how.

I've not identified a way of systematically reproducing this yet, but it seems to occur when you navigate backwards and forwards with the browser Back/Forward buttons several times and then try and click a submit link. I have also seen this happen with the standard Orbeon 3.9 sample applications, so it doesn't seem to be a problem unique to my application.

A stack trace is shown below.

Any thoughts on what part of the system this error relates to? Is it perhaps due to the way the state is now being managed?

Regards,
Neil

i've encountered that error message, too - mostly when trying to modify
the instance usind JavaScript (setvalue). I didn't find a way to debug
this, so i don't have any idea how to avoid it. But i'm sure it a
relatively "fresh" problem, it's maybe two or three weeks since i've
seen that error the first time.

All,

We plan to look into this, at least the case of the "back" which seems
to produce this in some cases.

If you have a reproducible case that do not involve browser
back/forward, please let us know.

Hi Erik,

Thanks for looking at this.

I've been trying to reproduce the problem, which appears to manifest itself differently depending on the web browser. I can reproduce the problem every time using Chrome as follows:

1. Setup: Tomcat 6.0.32 on Windows, Orbeon Forms 3.9.0.rc1.201103220245 CE, with Chrome (10.0.608.204)

2. Deploy RC1 3.9 Orbeon.war file

3. Navigate to the Xforms Wizard sample using Chrome e.g. http://localhost:8080/orbeon/xforms-wizard-pfc/

4. Enter a First Name. Press the Next button.

5. Press the Browser Back button once. This should restore the previous page including the entered name.

6. Now pressing the Next button causes the "Got unexpected request sequence number" error dialog to be displayed every time (for me).

I've also tried this with Internet Explorer 8 and Firefox 4. While neither of those seem to display the error dialog using the above procedure, it doesn't quite feel right. Firefox in particular doesn't seem to restore the values in the wizard - plus you get a really annoying "Confirm" dialog about "...Firefox must send information that will repeat any action...", which I can't seem to be able to turn off.

If there is anything else I can provide you to help track this down, please let me know.

Regards,
Neil

Neil,

Thanks a lot for these steps. We haven't looked at this yet but plan to!

Hi,

I don't know if this is a related issue, but there also seems to be a problem with updating instances, when a submission is called as a nested submission.

For instance, I have an XForm containing two submissions such as:

<xforms:submission id="data-submission" ref="$form/data" method="post" resource="data_resource" replace="none">
        <xforms:send ev:event="xforms-submit-done" submission="nested-submission"/>
</xforms:submission>

<xforms:submission id="nested-submission" ref="$form/nested_data" method="post" resource="nested_resource" replace="instance" instance="nested-data" />


Here the first submission runs, and so does the second nested one. However the instance is not actually replaced, so the form doesn't update itself. After the problem occurs the navigation links on the page no longer work, as per the original issue.

If I can provide more assistance in tracking this, please let me know.


Regards,
Neil

Hi Neil,

Sorry again about the delay—I will be looking into this browser back issue, and will follow up here as soon as I find something.

Alex

Hi Neil,

I doubt that the "nested submissions issue" where the instance doesn't get replaced as you expect it to be, is related to the back issue (unless this is happening on "back"). So it would be good if you could create a simple test case for us to reproduce this. If you need services to call, you can use the zip-states/zip-cities services, which are part of the XForms sandbox. You can find the full URL for those services in the snippets on:

http://wiki.orbeon.com/forms/doc/developer-guide/xbl-components/databound-select1

Alex

Hi Alex,

I've been trying to put together a minimal example of the nested issue I've encountered, but as is the way with these things, my first pass at doing so hasn't reproduced it yet. I'll keep trying and hopefully post an test case soon.

With respect to the "back" issue - thanks in advance for looking at this - much appreciated.

Regards,
Neil

Hi Neil,

This is now fixed. In case you want to test give this a shot, the fix will be in the next nightly builds (which also contain all the post 3.9 code), and of course it will be in the final 3.9. If you are interested in some background on why this was happened on Chrome, you can read more about it in the section "Restoring form fields on back" on:

http://wiki.orbeon.com/forms/doc/contributor-guide/browser#TOC-Restoring-form-fields-on-back

And for the "nested submissions issue", I'll keep an eye on a follow-up message from you with a test case.

Alex

Hi Erik,

I've now tried the nightly build from 16 April and this is definitely an improvement on the behaviour I was originally experience. Most of the original symptoms have gone which is good. That said, I found that I still occasionally see a "Got unexpected request sequence number". This seems to happen when I do a lot of "Back" button navigation, so I guess there is still a potential issue in there somewhere. I will try and find a way to reproduce with the standard examples.

With respect to the other issue I mentioned about nested submissions - I just can't seem to reproduce the issue I saw in isolation. For the time being I've rewritten my submission to refresh the entire page. When I have more time I will try and isolate the issue again.


One other point, unfortunately there does seem to be another side effect of the latest build. This occurs when logging off (i.e. invalidating the session). Now when logging out of an authenticated Tomcat 6 installation, I get the error stack shown at the end of this message.

Any thoughts on what has changed with the Orbeon Session Listener, and/or a way I can avoid this situation?

Regards,
Neil

Hi Neil,

I've now tried the nightly build from 16 April and this is definitely an improvement on the behaviour I was originally experience. Most of the original symptoms have gone which is good. That said, I found that I still occasionally see a "Got unexpected request sequence number". This seems to happen when I do a lot of "Back" button navigation, so I guess there is still a potential issue in there somewhere. I will try and find a way to reproduce with the standard examples.

Yes, please let us know if you find a way to reproduce this. The PFC is a good example to test the Back behavior, as you get a new "page" every time you hit Next or Previous, and hence can recreate a chain of pages which is as long as you wish.

With respect to the other issue I mentioned about nested submissions - I just can't seem to reproduce the issue I saw in isolation. For the time being I've rewritten my submission to refresh the entire page. When I have more time I will try and isolate the issue again.

Sounds good; you'll let us know when you find a way to reproduce this.

One other point, unfortunately there does seem to be another side effect of the latest build. This occurs when logging off (i.e. invalidating the session). Now when logging out of an authenticated Tomcat 6 installation, I get the error stack shown at the end of this message.

I'll let Erik answer this part of your message.

Hi,

I am getting same error when trying to edit source code on the form that has been created from the existing form but modified with Formbuilder afterwards.

Steps to reproduce:
- Copy source code from the existing form
- create new form, copy source code
- save, then edit metadata and change form name
- open source code, click on Apply button, first error (error type not specified) shows :



- click on "Close this dialog" and then click on Apply again, the error "Got unexpected request sequence number" comes up.




Afterwards it is not possible to edit source code.

I am using Orbeon version 3.9, Tomcat 6.0.20 and Chrome.
Same errors showed up using IE and FireFox.

Regards,

Jasenka Hadzikadunic

Hi Jasenka,

Does this happen with the 3.9 release, or a nightly build? Does this happen if you download a new build, reinstall it from scratch without changing anything to the configuration (I assume you have changes in your properties-local.xml), and follow the steps you described above?

Alex

Hi Alex,

I am using 3.9 PE stable version.
I have started the thread on the same item and provided more details in the support site https://orbeon.basecamphq.com/projects/4855361
If you prefer, we can move it to this thread.

Regards,

Jasenka

Jasenka & all,

Yes, let's handle this off list, so we can exchange logs and forms that are potentially private, and we'll report back here when we find something relevant to the community.

Alex
