1330	Unbalanced ModelicaAdditions: Class MultiBody_Examples_Loops_Fourbar1 has 2316 equation(s) and 2319 variable(s)	Adrian Pop	Adrian Pop	"After the new connection-set implementation the ModelicaAdditions model is not balanced anymore.

As far as I can see from the diff, see sort-new.txt and sort-old.txt there are two equations in\\
plus in sort-old (revision before the change) these two equations are in plus in the old model:
{{{
j2.axis.f = 0.0;
j1.axis.tau = 0.0;
}}}
However, these are protected connectors which have duplicates for these equations:
{{{
j1.axis.tau = j1.nn[1] * j1.tb[1] + (j1.nn[2] * j1.tb[2] + j1.nn[3] * j1.tb[3]);
j2.axis.f = j2.nn[1] * j2.fb[1] + (j2.nn[2] * j2.fb[2] + j2.nn[3] * j2.fb[3]);
}}}
and we deduced that the set-to-zero should be removed if the connector is protected, the flow is output\\
and another equation is present for the same variable."	defect	closed	high	Red October			fixed		Adrian Pop Adrian Pop Per Östlund Peter Aronsson
