Hi, after a Migration from 4.3.7 to 5.0.2 i get the following Traceback when i edit an existing Contentobject in the Editorarea. I add a link and when i save my object then comes the error. The same error occurs even when i disable the Linkintegritycheck. When i add new Content then also happen this, when in the editorarea is a link to a internal Object.

Traceback (innermost last):

I just worked around that in a project yesterday by:

  • First upgrading to 4.3.8-pending as an intermediate step

  • Clearing the reference catalog

  • Clearing and rebuilding portal_catalog

  • Installing plone.app.contenttypes

Here's part of my migration code running in plone4 before upgrading to plone5:

# clear the archetypes reference catalog
log.info("Clearing reference catalog")
portal.reference_catalog.manage_catalogClear()

# clean cruft from catalog
log.info("Rebuilding portal_catalog. This will take a loooong time.")
ctool = api.portal.get_tool('portal_catalog')
ctool.clearFindAndRebuild()

# migrate to plone.app.contenttypes
log.info("Enabling plone.app.contenttypes")
qi_tool.installProducts(['plone.app.contenttypes'])

Oh you're already on 4.3.7 you will likely not need 4.3.8-pending. But running the other steps may solve your problems.

It happens here:

https://github.com/zopefoundation/zope.intid/blob/3.7.2/src/zope/intid/init.py#L89

You see there are two occasions on which a KeyError can be raised. He was able to look up a key for the object, but then did not find the key in the intid tool.

I don't know, why the key is missing, it should not happen.
Either, you managed to find an edge case where linkintegrity gets broken. In that case, you would have had the same problem in 4.3, or some upgrade step did not work correctly. Maybe somebody else knows more.

Do you know, which of these steps was the required one?

No. I based my workaround on @fulv's documented issue:

Ok, after some attempts, i found a solution. normally, i had deinstalled all addons from portal quickinstaller in the zmi before i upgrade the instance. now, i didn't uninstalled the 'plone.app.intid' "addon", and all was fine. Sorry, it was my mistake, this should not be happen. :confused:
