[YANGTOOLS-1312] Refining leaf-list with "default" Created: 19/Aug/21  Updated: 20/Oct/21  Resolved: 19/Aug/21

 Description   

I have modeled my yang structure with a grouping, which has a leaf-list. When this grouping is used, I have refined the leaf-list to set a default value. However the yangtools gives an error

"can not perform refine of 'DEFAULT' for the target 'LEAF_LIST'. "

Pyang works fine with no error/warning.

I have looked at the RFC https://datatracker.ietf.org/doc/html/rfc7950#section-7.13.2 and it seems supported.

Can you please help with this.

 

grouping abcded {
  container xyz {
    description "blah";
    leaf zyx { type boolean; description "blah blah..."; }
    leaf pqr { type string; description "yada yada..."; }
    leaf rst { type boolean; description "more blah..."; }
    leaf-list abc { type abc-type; description "more yada..."; }
  }
}
uses somewhere:abcded {
  refine "xyz/abcd" { default "all"; }
}

typedef abc-type {
  description "Used to indicate the types";
  type enumeration {
    enum one { description "first type"; value 1; }
    enum two { description "second type"; value 2; }
    enum three { description "third type"; value 3; }
    enum four { description "fourth type; value 4; }
    enum all { description "Reuse all possible options"; value 99; }
  }
}

Hi Robert, what would the MD-SAL version that will use 6.0.8 yangtools? Currently when I use MD-SAL 7.0.8 it still uses 6.0.7 yangtool plugin. Is there a way to explicitly specify yangtools 6.0.8 in the pom?

Sorry I'm novice to the maven.

yang-maven-plugin wiring is done here: https://github.com/opendaylight/mdsal/blob/v7.0.8/binding/binding-parent/pom.xml#L59-L61 and you are inheriting it via the <parent/> clausule. I am not sure how you'd go about overriding it, sorry

as for yangtools-6.0.8, it should be release in a couple of weeks and then it's going to hop on whatever next mdsal release is next in that train ... mdsal-7.0.10 I guess.

Thanks rovarga Is there is any link to see next release dates for md-sal? I tried looking, but couldn't find any. Our YANG models are supposed to be released by end of sept 21. If we could get a this fix before that, it would be great.

Again many thanks for all the help!

yangtools-6.0.8 is out there, as is mdsal-7.0.10. Sorry about the delay.
