Quote from the site:
Disjunctive field constraints connectives could also be used and would
not result in multiple rule generation.
Person( eyeColour == "blue"||"green" )
Any idea on why the "from" is not correct?
$rt: ResourceType( )
$perm: ResourceTypePermission( accessType != AccessType.READ )
from $rt.permissions
Role(id == $perm.role.id)
Correct is either:
Role(name == "christws-admin" || == "site-admin" || ==
"resource-type-admin")
Or:
Role(name in ( "christws-admin", "site-admin",
"resource-type-admin") )
Where in the docs it says that the syntax you used is correct?
