When creating a Domian from a postgres data source, materialized views do not appear in the domain designer. I followed the instructions at https://community.jaspersoft.com/documentation/tibco-jasperreports-server-administrator-guide/v71/configuring-domains#Accessing_Materialized_Views and added <value>MATERIALIZED VIEW</value> as described. I also rebooted the server in case that was necessary. My materialized views still don't appear in the domain designer. Any suggestions? As an additional troubleshooting step, I commenting out the <value>VIEW</value> line immediately above my new <value>MATERIALIZED VIEW</value> line , rebooted, and as expected did not see (non-materialized) views in the domain designer. I then un-commented the VIEW line, rebooted, and again saw non-materialized views as expected. So that confirmed I at least had the correct file and area.
