I am facing the same issue.
Since the Content Validator update (>5.10) lookless tiles can be referred to new model names.
However for me, the dashboard is still referencing to the old model name:
- In Content Validator, changed the Model reference from old to new model name
- Tile works individually
- However on dashboard, tiles display 'View Not Found'
- Explore From Here generates URL with old explore name:
...looker.com/explore/ [old model] / [label]
- Changing URL will work:
...looker.com/explore/ [new model] / [label]
- Therefore I think the Content Validator does not update dashboard references
I don't know an easy way to do this now. For LookML dashboards I can change it there, however these are the dashboards created from the UI in Spaces..
