Error while previewing form

Q&A
1

Hello!

I work with Bonita BPM Community edition. I have a process was made on v7.0.0. Now I want to migrate to v7.0.2, but when I open any form from my process in designer (v7.0.2) and click “Preview”, I get an error

On v7.0.0 and 7.0.1 everything is OK, but on 7.0.2+ preview doesn’t work for new forms also.

P.S. My collegue has a reverse situation: he gets an error while previewing forms on v7.0.0 and 7.0.1.

If I understand correctly your issue is that an error is logged but you don’t experience any other abnormal behavior.

The issue about this specific stacktrace has been fixed in Bonita BPM 7.1.0. You might want to upgrade to this version to get the latest bug fix.

Thanks for the response!

I installed Bonita v7.1.0 and error has changed (catalina log):

In addition to error in log, form preview run as blank page (on v7.0.2 and 7.0.3 too). Any widgets, which I put on the form, aren’t loaded.
In chrome console I get next errors:

Is it possible for you to share the form so I can do some test and try to reproduce the issue?

5

It’s not a concrete form. If I create a new form in 7.0.2 I get the same error.

6

In order to reproduce the issue I need to make sure that I get correctly all steps you performed.

Can you confirm the scenario to reproduce the issue and answer below questions?

  • You download Bonita BPM Studio Community 7.1.0. Which version Windows / Mac / Linux ? Which packaging (.exe, .dmg, .run, .zip)?
  • You install Bonita BPM Studio
  • You create a new process
  • You define a process instantiation form by selecting the pool, going to Execution -> Instantiation form and clicking on the pencil icon
  • You add a widget on the form. Which kind of widget? Any specific configuration?
  • You click on Savebutton
  • You click on Preview button
  • A new web browser window pop up with an empty page
  • You check the content of the latest catalina log file in Studio folder: `workspace/tomcat/logs/catalina.2015-MM-DD.log and you get the stack trace you shared.

Can you also share the full content of the logs folder? To limit the log size, can you close the Studio, remove all logs files, restart the Studio, do your test again and at this stage zip the log folder.

Thanks

You define steps correctly.

  1. I tried to install different versions (7.0.2 x32, 7.0.2 x64, 7.0.3, 7.1.0). All for Windows, .exe packaging.
  2. I tried to create new form with different widgets (button, text, link) and to import form from v7.0.0. I get the same result.
  3. Below stacktrace on v7.0.2:
    logs

7.1.0 logs

Can you share the 7.1.0 log files? Because the error reported in 7.0.2 log files should be fixed in 7.1.0.

Thanks

Your colleagues gave advice to clear the cache in the browser. That helped.
Thanks.
