[#6396] - cannot access Postgresql meterialized views from domain designer

We're trying to build a domain using jasperserver 6.1.1 based on EntrepriseDB (Postgresql)
We're using a JNDI datasource to access EntrepriseDB and we cannot access materialized views from the domain builder... (I can access them from standard reports)

I did the changes as written in http://community.jaspersoft.com/documentation/tibco-jasperreports-server... but it's still not showing materialized views.

It also doesn't work whether we're trying with a JDBC datasource or a virtual datasource.

Is there something else to do? something different? Or is there a bug in Jasperserver?

Thanks,
