[YANGTOOLS-749] Unable to create LeafRefContext for leafref from different model imported with different than default prefix

Sun, 10 Apr 2022 18:35:57 +0000

Situation

module ioam-sb-trace {

import ietf-interfaces

{ prefix "ietf-if"; }

...

leaf intf-name {
type ietf-if:interface-ref;
mandatory true;
description
"Instance of ietf-interfaces:interface-ref";
}

-------------------------
module ietf-interfaces {

yang-version 1;

namespace
"urn:ietf:params:xml:ns:yang:ietf-interfaces";

prefix if;

...
typedef interface-ref {
type leafref

{ path "/if:interfaces/if:interface/if:name"; }

description
"This type is used by data models that need to reference
configured interfaces.";
}

In this situation, SchemaContext is created fine, but when trying to construct LeafRefContext, following error is showed

-----------------------
If changed like so, LeafRefContext is created fine

...
import ietf-interfaces

{ prefix "if"; }

<-- default prefix for model ietf-interfaces
...

leaf intf-name {
type if:interface-ref;
mandatory true;
description
"Instance of ietf-interfaces:interface-ref";
}
