[YANGTOOLS-1408] Deviation of augmented case node fails

Sat, 19 Mar 2022 15:26:53 +0000

Parsing of Yang sources with a deviated case node fails if the case node was created with augmentation without explicit case statement.

For example, parsing of the following two modules fails.

module orig {
    namespace "urn:orig";
    prefix orig;

    container foo {
        choice bar {
            leaf bar1 {
                type string;
            }
        }
    }

    augment /foo/bar {
        leaf bar2 {
            type string;
        }
    }
}

module deviate {
    namespace "urn:deviate";
    prefix dev;

    import orig {
        prefix orig;
    }

    deviation /orig:foo/orig:bar/orig:bar2 {
        deviate not-supported;
    }
}

Error message says that the case node is not found:
