Plone 5.1: Collection view fails with "AttributeError: 'FlareContentListingObject' object has no attribute 'UID'"

[tisto]

Plone 5.1 with collective.solr master branch.

1. Create collection with query:

  >>> query = [{'i': 'SearchableText',
  ...           'o': 'plone.app.querystring.operation.string.contains',
  ...           'v': 'new'}]

2. Go to collection view

We’re sorry, but there seems to be an error…
Here is the full error message:

@gforcada it seems FlareContentListingObject stopped implementing the IContentListingObject interface in Plone 5.1. Was the PLIP to merge c.indexing into the core ever tested with collective.solr?

[gforcada]

@tisto yes it was, and I wanted to provide a pull request for it, but at that time there was a major refactoring (I guess the 5.0 release) and somehow it fail through the cracks on my todo list

[tisto]

@gforcada ok, good. There is an open pull request now:

#183

What kind of amendments do we have to do on c.solr?

[tisto]

@gforcada do you plan to still create a pull request and work on this?

[gforcada]

yes/no... whenever we (at der Freitag) upgrade to 5.1 I will work on it for sure, but as that's not high on our top priority list it can take a while, at least I will not start that right now.
