This happens when the memory optimization is enabled in the controller:

<clixon-config xmlns="http://clicon.org/config">
   <autocli>
     <grouping-treeref>true</grouping-treeref>                <----

An example from ietf-yang-library.yang is:

  grouping module-implementation-parameters {
    description
      "Parameters for describing the implementation of a module.";
    leaf-list feature {
      type yang:yang-identifier;
    ...
    leaf-list deviation {
      type leafref {
        path "../../module/name";
      }

The path "../.." goes beyond the scope of the grouping and assumes that there is a "module" node in the context where the "uses" is done. I think is broken YANG.
