I am trying to solve this problem: Drupal 7 Most Popular Tags in a list as a block: How? with Views 7.x-3.0-rc1.
- create a view of terms
- add a required relationship to "content using tags"
- set use aggregation: yes
- add the "term name" field a second time, set one of the to "aggregation type: count"
- add "term name" as a sort criteria, set "aggregation type: count"
A sample view is at http://drupalbin.com/19467
It works until I try to sort the list; in that case, I get an error when adding a sort criteria. If I set "aggregation type: count" the sort-criteria changes to "Broken/missing handler" and it is not sorting.
Do you have any idea? Am I doing something wrong?
