Sateflow: Indexing an array of size 1

Hi,

I need to index an array that can be of size 1 to x. Indexing in gerneral is no issue, as long as the size of the array is >1 (e.g. using A[x]). But as soon as the array size is 1 I get the following error for a transition check:

[i == 0 && A[i] >= B[i]]

Array dimension mismatch for data A.

Size of a is defined empty.

Anyone an idea for a generic approach?

Thanks!
