3076	Inconsistent behavior of array vs. non-array connect	stuchl4n3k@…	somebody	"'''Description:'''
I have two simple models (call them A and B) with components. 
When I connect the individual components (variables) like: connect(A.foo1, A.foo2);, the model simulation works as expected.

But in model B I have them inside an array and connecting them like: connect(B.foo[1], B.foo[2]); (in a for loop).
The simulation of B fails, giving me:

Both models work in Dymola. 

'''How to reproduce:'''
1) See the attached model.
2) Simulate ArrayBug.IzhNetNeuronTest2 time 0-100 (Dassl tolerance 1e-6, 500 intervals, max integration order 5).
