OMC does not detect as error the use of noEvent clause in a When structure

[Andrea Bartolini]

Consider the following model:

model TestNoEvent
  discrete Real x1,x2;
  Real y;
algorithm
  when time>2 then
    x1 := time;
  end when;
  when noEvent(time>2) then  // this is an error !!!
    x2 := time;
  end when;
equation
    y=x1+x2;
end TestNoEvent;

When the model is checked (e.g. in OMedit) no error is detected nor any warning is shown, the model passes the test, as reported in attached file CheckModel.png.

Simulating the model, the simulation ends without errors and the "when" structure with the noEvent clause does not trigger the condition "time>2", as shown in attached file Result.png.

The expected behavior should be the detection of the "noEvent" clause in the "when" structure as an error, and consequently the model check failure.

Simulation of model should end with an error.
