[midPoint] Search for shadow attribute in 4.7.3

[miroslav.tankovic at orange.com]

Hello,
I'd like to list users with specific value of attribute on specific resource and I'm trying to follow this documentation
https://docs.evolveum.com/midpoint/reference/before-4.8/concepts/query/midpoint-query-language/introduction/#users-with-account-on-specific-resource
(It is "before-4.8 as we have Midpoint 4.7.3 installed.)

In Users - Axiom query it works if I search only for users with specific resource and kind/intent:
linkRef/@ matches ( . type ShadowType  and resourceRef matches (oid = "70322d99-b62c-4ab6-8d2e-92c0edb9f1be") and kind = "account" and intent = "person" )

But if I add required shadow attribute Stat2 to query
linkRef/@ matches ( . type ShadowType  and resourceRef matches (oid = "70322d99-b62c-4ab6-8d2e-92c0edb9f1be") and kind = "account" and intent = "person" and attributes/Stat2 = "1" )
it fails with error
Path attributes/Stat2 is not present in type {http://midpoint.evolveum.com/xml/ns/public/common/common-3}ShadowType

It is not possible to search shadow attributes? Or Am I doing it wrong?

Thanks in advance!
Miro
