[YANGTOOLS-1201] Unable to use prefix in augmention when argument inside submodule

Thu, 10 Dec 2020 15:33:41 +0000

Problem with using prefix inside a when argument. This happens only inside a submodule trying to augment nodes from module to which it belongs.

Example [1]:

submodule ietf-snmp-community { 
  belongs-to ietf-snmp { 
    prefix snmp; 
  }
 ...
  augment /snmp:snmp/snmp:target { 
    when "snmp:v1 or snmp:v2c";
    ...
  }
}

Error message:

Caused by: org.opendaylight.yangtools.yang.parser.spi.source.SourceException: Argument "snmp:v1 or snmp:v2c" is not valid XPath string [at experimental/ietf-extracted-YANG-modules/ietf-snmp-community@2014-05-06.yang:192:4]
...
Caused by: javax.xml.xpath.XPathExpressionException: java.lang.IllegalArgumentException: Prefix snmp is not bound
