Update Community Version 4.0.e -> 4.2.c: Wikiproblems

[fochlac]

Hi,

I've updated Alfresco from 4.0.e to 4.2.c and encountered an issue while migrating the data according to the Backup and Restore-procedures. On the first glance everything was fine, however, I encountered a problem with the wikimodule of our main site:
The wikipages in the dashlets on the site-dashboard were displayed just fine, yet, as soon as I tried to open the same pages within the Wikimodule of the site it would only show blank sites.
This error only happens on the main site.
No error is shown in the logs.
The backup is working with Alfresco Community 4.0.e.
Older Backups cause the same error.
Modifying or creating Wikipages does not help either. The new/modified page will remain blank.

For testing purpose I have been using an unmodified Version of Alfresco 4.2.c.
I could not reproduce this issue on other sites.

I would be very grateful for any ideas regarding this issue. If you need more informations please ask right away.

Thanks,
Florian

Same problem here, haven't found a lot of references yet. Updated from 4.0.

Found this in the log:

Caused by: org.alfresco.service.cmr.repository.TemplateException: 010217868 Error during processing of the template 'Expression jsonUtils.encodeJSONString(x) is undefined on line 2, column 15 in org/alfresco/slingshot/wiki/page.get.json.ftl.'. Please contact your system administrator.

Well, I'm the system administrator and for now I don have a clue

I noticed that in Firefox I was not able to see the content of the wiki pages, but I was able to see them on my Ipad app. I forwarded all my wiki pages in email, deleted all the wikipages not via Share but via Alfresco login. Tried to restore them as admin in Share which brought the problem back again. Deleted them once again via Alfresco login and created new wiki pages with the emails and it looks like error messages have gone and everything is back to normal 😉
