[main] ERROR IEC61850_7_420 AbstractLNs7_420GridCodeModes::FrequencyActivePowerLN : [constraint 'AllOnlyOneGroup(1)' for inexisting 'DepRef']

Proposal

Analysis
Believed due to name change to HzWCrvRef
HzWCrv has constraint AllOnlyOneGroup(1)

WGra and ChaWGra are both AllOnlyOneGroup(2)

Proposal
Change constraint AllOnlyOneGroup(1) to refer to HzWCrvRef
