Visual help in fixing broken local variable linkage

[Intaris]

I sometimes delete controls from the BD and realise some time (from milliseconds to minutes) that I have some broken local variables.

I get greeted by the hugely informative imagery as shown below:

Yeah, good luck realising what exactly you deleted by mistake.  No name, no way of finding out what the local PREVIOUSLY linked to.

I suggest retaining at least the name of the Control / Indicator the local was linked to so that the poor programmer (me) has some fighting change of undoing the error.  Bear in mind there could be many changes made to a VI before this kind of thing is notices so a simply "undo" fix could end up being VERY awkward indeed.

An example of how this could look:

Here I at least know WHAT I have deleted by mistake.

Sure... Like this?

I've got like a feeling that this is what we still will have to live with in 2013...

Yup, it still behaves like that. There's quite a bit of tweaking in the algorithm that decides how to arrange the new subVI's conpane (in 2011 and later). I must confess that my test matrix did not include much in the way of 0-output subVIs. I'll file myself a CAR to tweak it for this case. Hopefully you can take some solace in the fact that, if that flat sequence had any outputs, the numeric and string terminals would be in the positions you expect.

Thanks. Now of course, an alternative would be to implement this idea...

Well, Darren, what about this one:

Create subVI yields:

whose conpane looks like this:

I'm going to guess the logic behind that one is pretty simple - put refs on top. That's why the DVR is on top and the other ref is below it. The rest is just putting the others in while skipping the place for the error terminal.

I suggest that you start a separate threads for these. I'm also assuming that if you can give NI actual VIs that don't behave as you expect, they can at least look at what's going on.
