findDiscreteEquation failed for algorithm

[Jens Frenkel]

For the following model

model simple4
  type modetype = enumeration(on, off);
  modetype mode(start = modetype.off);
  Real v(start = 0);
algorithm
  when (v > 0.5) then
    mode := modetype.on;
  elsewhen (v <= 0.5) then
    mode := modetype.off;
  end when;
equation
  if (mode == modetype.off) then
    v = time * 1.1;
  else
    v = time * 1.1 + 40;
  end if;
end simple4;

The function  findDiscreteEquation failed to get the discrete equation (the algorithm) for the discrete variable mode.

[Willi Braun]

The issue for that model is that we don't support mixed systems involving something different than Boolean and also no other equation type than simple equations. So if we pass that function, somewhere else issue will raise.

Suggestion for the model try to break that algebraic loop by insert pre operator.

Fixed and test added in r22641.

It doesn't make sense to keep closed ticket in the "Future" milestone that were simply forgotten to assign to the correct milestone in the past.

[Martin Sjölund]

Removing the pre1.9.4 milestone in favor of 1.9.4.
