Array[1,dim] get's changed to Array[dim,1]

[Andreas Heuermann]

I have a model that calls a built-in function point-wise on a vector input with dimension [1,dim], but the output of that function is of dimension [dim,1].

setCommandLineOptions("-d=newInst,optdaedump");
loadString("
model mwe 
  Real vectorA[1,4];
equation
  vectorA = tanh( {{10,20,30,40}} );
end mwe;
"); getErrorString();
simulate(mwe); getErrorString();

When I dump the equation at the first point in the frontend with optdaedump I'll get

Equations (1, 4)
========================================
1/1 (4): vectorA = {{tanh(10.0)}, {tanh(20.0)}, {tanh(30.0)}, {tanh(40.0)}}   [dynamic |0|0|0|0|]

but I would expect to get the same dimension as the input was, so:

vectorA = {{tanh(10.0), tanh(20.0), tanh(30.0), tanh(40.0)}

This prevents me from solving related ticket #6266.

@mahge930, @perost Any idea where to look at for this?

By the way, if I use the old frontend it gets flattened out is completely wrong.
