Unexpected keyword error when using multiple default values in leaf-list refine statement #787

Open splinc opened 2 years ago

splinc commented 2 years ago

In yang 1.1 it is possible to refine a leaf list with repeated default statements but this is not handled correctly by pyang (v2.5.2) Using the attached file (test.yang) I see the following output

pyang -f tree test.yang test.yang:20: error: unexpected keyword "default" module: test +--rw test +--rw test-list* string

Note:

Unfortunately we are using pyang to process a yang model that includes 3rd party yang files that use this pattern to refine leaf-lists so there is no obvious workaround in our plugins.

Same issue observed on tail-f module:
