entity VDiffWithRule

as select from testauto.VDiffWithRule

order by seq

actions {

action editDiff(inputCheckpointId:UUID, variable : String(50), skipCheck : Boolean) returns VDiffWithRule;

};

Hello Bruce,

Unfortunately, it is not possible to specify a default value for action parameters with the current version of CDL.

Best Regards,

Patrice
