1179	Incomplete propagation of modifications when using type alias	Adrian Pop	Adrian Pop	"This model:
{{{
model AliasType
  type B = Real[4](each start=2);
  B b(each unit=""K"");
  parameter Real[4] a = zeros(4);
equation
  b = a;
end AliasType;
}}}

is flattened to:

{{{
fclass AliasType
Real b[1](unit = ""K"");
Real b[2](unit = ""K"");
Real b[3](unit = ""K"");
Real b[4](unit = ""K"");
parameter Real a[1] = 0.0;
parameter Real a[2] = 0.0;
parameter Real a[3] = 0.0;
parameter Real a[4] = 0.0;
equation
  b[1] = a[1];
  b[2] = a[2];
  b[3] = a[3];
  b[4] = a[4];
end AliasType;
}}}

which is missing the start attribute for elements of b.\\
\\
The problem appears also when extending from a type alias:
{{{
model ExtendedFromAliasType
  type B = Real[4](each start=2);
  type Extra
    extends B(each unit=""K"");
  end Extra;
  Extra b;
  parameter Real[4] a = zeros(4);
equation
  b = a;
end ExtendedFromAliasType;
}}}

flattens to:

{{{
fclass ExtendedFromAliasType
Real b[1];
Real b[2];
Real b[3];
Real b[4];
parameter Real a[1] = 0.0;
parameter Real a[2] = 0.0;
parameter Real a[3] = 0.0;
parameter Real a[4] = 0.0;
equation
  b[1] = a[1];
  b[2] = a[2];
  b[3] = a[3];
  b[4] = a[4];
end ExtendedFromAliasType;
}}}

which is missing ALL the modifications for elements of b.\\"	defect	closed	high				fixed		Adrian Pop Per Östlund
