event-bug

[Lennart Ochel]

Here is a short and strange bug regarding events/sample/when. I have already created a test (see r14752).

  model sample2
    Real x, y;
    Boolean condition1;
    Boolean condition2;
  algorithm
    condition1 := sample(0.0, 0.1);
    condition2 := sample(0.0, 0.1);
    when condition1 then
      x := pre(x) + 0.1;
    end when;
    when condition2 then
      y := pre(y) + 0.1;
    end when;
  end sample2;

I would expect that x and y has to be the same - omc not.

This is because of our strange helpVars. We generate for each sample-call one helpVar, but we activate during simulation just the first one for equal sample-calls.

I will remove all helpVars as they are just a historical workaround. I already have started to fix this.
