MetaModelica: loop over list<Integer>

[jens.schoenbohm@…]

Using an Integer from a list<Integer> as array index will give the wrong array component, if the list is part of a record.

Example:

uniontype Index

record INDEX

list<Integer> idx;

end INDEX;

end Index;

uniontype Compo
record COMPO

array<Real> co;

end COMPO;
end Compo;

Supposed we have a Compo called compo and an Index called index, the for loop gives wrong array components:

for k in index.idx loop

print(String(k));
r := compo.co[k];

end for;

The print command gives the correct number, but k as array index
seems to have twice the value of the list member. So if it exceeds the array bounds we will see an error otherwise r has a wrong value.

A known workaround: Assign k to an integer variable and use it instead of k or do an integer operation with k at the place where you use k. For instance r := compo.co[k+0].
