Problem evaluating numerical values for binding expressions

[jakesson]

There seems to be an error in DAELow.updateVariables. In the following case

.
.
parameter Real a=4;
parameter Real b=4*a;
.
.

the DAELow.Var record corresponding to b has and empty bindValue - shouldn't
this attribute be set in DAELow.updateVariables? For variables initiated with a
numeric value, like a above, there is no problem.

[jakesson]

Simple additional example:

class BindingBug

parameter Real x_0 = 1;
Real x(start=x_0);

equation
der(x)=-x;
end BindingBug;

The start attribute of x is not evaluated correctly and set in the simulation
init file.

[Peter Aronsson]

If a start value depends on parameters it will have the "default" value 0.0 in
the init file. It is up to the solver to call initial_function() which will set
the correct value, based on the parameter value.
