Hi,

I have cdb-set_case function with all parameter correct except case parameter. I have passed “” parameter as case value. and my yang model dont have any default for choice.

I see that cdb_set_case should fail but it passed. Let me know if my understanding is correct.

            container case_example {
                    choice case_selector {
                            case value_case_1 {
                                    leaf case_1 {
                                            type string;
                                    }
                            }
                            case value_case_2 {
                                    leaf case_2 {
                                            type string;
                                    }
                            }
                    }
            }

Hi sudhanshu,

You use “” to unselect a selected case.

Quick demo with your YANG:
