Re: Error: "The length of the specified array is zero."

Looks like "Russian" is not in your dressingsList.
Hence, you get a length zero array.

Hi folks,

I’m trying to figure out what is wrong in the 
attached model; I am trying to extract an
element from an array, and from what I can tell, I think it should work.

The problem occurs with both ArrayElement and 
ArrayLength (I haven’t tested with
similar other actors). Without one of these in 
the path, I get tokens of the form e.g.
{4} on the “Found Indices” display. This looks 
like an array of length 1. As soon as I
insert ArrayElement or ArrayLength in the flow, 
I get an error, “The length of the
specified array is zero.”

I’ve been stepping through this in Eclipse but I 
haven’t found where the problem occurs.

Again, it seems like what is coming out of the 
Expression actor are in fact arrays, so
ArrayLength (or similar) should be happy… am I missing something basic?

Thanks for any tips,
