Issue with smooth() in the NF

[casella]

Please check ​https://libraries.openmodelica.org/branches/newInst/Modelica_3.2.2/files/Modelica_3.2.2_Modelica.Electrical.Analog.Examples.SimpleTriacCircuit.err

The following error is reported:

Error: Cannot resolve type of expression
' simpleTriac.thyristor.vConmain + smooth(0, ifsimpleTriac.thyristor.iGK < 0.95 .* simpleTriac.thyristor.IGT then 0.0
else ifsimpleTriac.thyristor.iGK < 0.95 .* simpleTriac.thyristor.IGT + 0.001 then 10000.0 .* (simpleTriac.thyristor.iGK - 0.95 .* simpleTriac.thyristor.IGT) .* simpleTriac.thyristor.vAK 
else 10.0 .* simpleTriac.thyristor.vAK) '. 
The operands have types ' Real + <RealArrayOrRecord> ' in component 
:
Addition operations involving an array and a scalar are not valid
in Modelica. Try using elementwise operator '.+'.

It is not clear to me if the problem is with smooth or with the if-expression (or both), but clearly the second operand should be Real as well.

It is also not clear why the .* operator is reported in the error message.
