Array Control allows Negative Index on FPGA

[elset191]

I couldn't find anything on this topic through NIs search or Google.  I can't be the only one who's seen it though.

I have an array control on the front panel of my FPGA VI and I was trying to get back to the start using the indexing arrows.  Much to my surprise it let me blow right by the start, index 0, and into the negative indices.  Is this intended?  Why?  Bug?

When I try to initialize the value on the FP it goes back to it's default grey disabled state, so it seems like it knows I shouldn't be there.  Also at -1 all visible elements are grey instead of just the first.

(Also it seems I found a bug in whatever version of CCT I'm using, the index is cut off my main array)

It's a bug, reported as CAR 130548. It's primarily cosmetic, as you can't assign values to any of the array elements at negative indices.
