Cannot register event for array of references on a ConPane? (code included)

[JackDunaway]

Can someone describe why Error 1 happens? It appears you cannot dynamically register an array of control references if the array is connected on the ConPane -- disconnect from the ConPane, and the error goes away. And it's just for arrays, not scalars. (LV2012 VI attached)

Hate to be a bearer of bad news but it is a bug that has been reported as CAR 366331. It was originally reported at http://forums.ni.com/t5/LabVIEW/2012-Dynamic-Event-Registration-Array-of-Controls/m-p/2120100/highlight/true#M688441.

Thanks, James! I've chimed in and cross-posted on that thread. (Bad news? This is kinda great news, for my sanity....)

And here's a janky workaround, instead exposing a variant on the ConPane then converting inside the SubVI:

Here's a new fix that is much better than the Variant fix: it looks like the "Always Copy" node once again pulls through as the CAR-buster:

Once again I will suggest that the icon of the Always Copy node should be changed to a Band-Aid. A Roach Motel would also work, but that is probably harder to draw in such a small space.

Now I *really* want to know what's going on under the hood that would cause the bug-- and for the primitive to automagically fix it...

How the heck did you figure out this workaround?

To adapt the $10k engineering invoice joke -- "$1 for the hammer strike, $99 for knowing where to strike it, and $9900 for all the recreational programming and nights reading LAVA, Darin.K, et al."
