4853	Expand arrays in when conditions with the NF	Francesco Casella	Per Östlund	"Please consider the [https://libraries.openmodelica.org/branches/newInst/ScalableTestSuite/files/ScalableTestSuite_ScalableTestSuite.Elementary.WhenEvents.Verification.ManyEventsManyConditions.err ScalableTestSuite.Elementary.WhenEvents.Verification.ManyEventsManyConditions] model.

The old FE the when equation by expanding the vector condition
{{{
    when {e[1], e[2], e[3], e[4], e[5], e[6], e[7], e[8], e[9], e[10], e[11], e[12], e[13], e[14], e[15], e[16], e[17], e[18], e[19], e[20]} then
      v = 1 + pre(v);
    end when;
}}}
while the new FE keeps it as a vector
{{{
    when e then
      v = 1 + pre(v);
    end when;
}}} 
which subsequently causes the code generation to fail.

As long as the NF is eventually generating flat scalarized DAEs, I think it should also expand the vector expression in the when statement, when generating the DAE data structure."	defect	closed	high	2.0.0	New Instantiation		fixed
