#1107 closed defect (fixed)

if returning a constant vector fails

Description

Hi,

the following model cannot be compiled:

model ifBug

Real[2] t;

equation

t = if (time < 0.5) then {0,0} else {1,1};

end ifBug;

when this model is simulated using OMC, following error message is being issued:

record SimulationResult

resultFile = "Simulation failed.

Internal error code generation of expression CAST(/tp:REAL[2]/, if time < 0.5 then {0,0} else {1,1}) failed

"
end SimulationResult;

Presumably, the OMC wants to "scalarise" the if equation. Instead of extracting the corresponding elements it tries to use the [index] operator and fails.

This seems to work in trunk now.
