It is still not fixed. In case of following configuration.
"InvalidValue" was in "Switch" class.
Is it invalid to put a SteeringParameterField after SteeringParameterGroup ?

<GlobalSteeringParameters>
  <SteeringParameterGroup>
    <SPGroupName>Switch</SPGroupName>
    <SteeringParameterField>
      <SPFieldName>Piedi</SPFieldName>
      <SPFieldType>Bool_t</SPFieldType>
      <SPFieldInitialization>0</SPFieldInitialization>
      <SPFieldComment>Switch for pedestal calculation</SPFieldComment>
    </SteeringParameterField>
  </SteeringParameterGroup>
  <SteeringParameterField>
    <SPFieldName>InvalidValue</SPFieldName>
    <SPFieldType>Float_t</SPFieldType>
    <SPFieldInitialization>-1000</SPFieldInitialization>
    <SPFieldComment>Invalid value</SPFieldComment>
  </SteeringParameterField>
</GlobalSteeringParameters>
