modelica - When .. elsewhen equations seems to be reversed in Wolfram Systemmodeler -


when try simple modelica code in wolfram systemmodeler:

model bug   integer y(start = 1); equation   when time > 0.2     y = 5 "y = 2";   elsewhen time > 0.4     y = 4 "y = 3";   elsewhen time > 0.6     y = 3 "y = 4";   elsewhen time > 0.8     y = 2 "y = 5";   end when; end bug;

the result 1, 2, 3, 4, 5, this: model bug simulatiom. when-equations seems activated in reverse order.

on othe hand, changing "equation" "algorithm", , (of course) "=" ":=" code turns:

model nobug   integer y(start = 1); algorithm   when time > 0.2     y := 5;   elsewhen time > 0.4     y := 4;   elsewhen time > 0.6     y := 3;   elsewhen time > 0.8     y := 2;   end when; end nobug;

and result expected, 1, 5, 4, 3, 2, this: model nobug simulation

is relatively basic problem in wolfram systemmodeler implementation, or there else cannot see?
