metadata extension

Hello !

I need a property which has different lists of values depending on a folder of the resource. I'm trying to create metadata extension using Prerequisites" target="_blank">https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/645d4357-0701-0010-07bd-a2e">Prerequisites and Relevant Knowledge Management APIs as an example.

There is a problem - how to get the folder of the resource from the method getAllowedValues ?

The parameter metaContext is always null and there seems to be no other way to get it.
