Events dataviz dashlet bug and breaking dashboard
Created by: gobnat
This is happening
It also then breaks the dashboard configuration screen as follows:
It is not possible to select, move or delete anything on the above config screen.
Appears to be throwing this exception:
dc.errors.InvalidStateException message: "Mandatory attribute chart.group is missing on chart[#participants]"
Can only then fix by deleting the dashlet and completely reloading the page.
Error originally occured on a new civi install with no events but the problem persisted even after events were created and participants added to the events.
Using CiviCRM 5.3
