Need to be able to filter records based on User Role

This worked also for me. Is there any hope that a thing like Region/Region1 in ${security.user.roles}
may work?

That won't work but this will:

Region/Region1 in (${ => "'" + role + "'").join(', ')})

I'm also to try filter data in a datagrid by user role, I have a single table "Funds" and column 'Fund'. My roles match the entries in Funds. 100 funds 100 roles. I've tried to filter on load event

${event.filter ? event.filter + ' and ' : ''}Fund in (${ => "'" + role + "'").join(', ')})

Also have a admin role that needs to access the all.

Help appreciated.
