Can't use a parameter to set the initial value of a state variable

[AlbertoLeva]

Initialising with a start value given as parameter does not seem to work.
For example, in a model containing something like

model Tank
...
Modelica.SIunits.length level(start=l_start);
...
parameter Modelica.SIunits.length l_start=0 "initial tank level [m]";
...
end Tank;
...
Model Plant;
...
Tank Tank1(...,l_start=1,...);
...
end Plant;

the value of parameter l_start has no effect.

I have also tried to fill initial values in Plant_init.txt, as suggested in
​http://www.ida.liu.se/~pelab/modelica/OpenModelica/releases/1.3.1/doc/OpenModelicaImplStatus-2005-10-11.html.
It didn't work too, as the default value (0 in the example above) seems to
override unconditionally.

Is it possible to have the parameter substituted as "start" value prior to the
compilation? Note that not having parametric initialisation (and also having to
tinker with a txt file each time) is very annoying when several instances of a
model have to be used, with different initial states (typical e.g. of
thermohydraulic models).

Thank you in advance for your attention.
