Error Cluster Bug Report (LV 2011)

[X.]

As I was trying to comment on an Idea Exchange Thread, I stumbled upon this bug.

Drop the following on a diagram:

Then try to "Create Indicator" from the OR function output:

Then Run the VI (or try to compile it using Ravens Fan's favorite trick of Ctrl-Run Arrow). Here is what I get:

The VI is now broken.

If I delete the indicator, it doesn't fix the problem. If I delete the operator, it does.

[RavensFan]

I'll confirm it for LV2011.

I don't know what the expected result should be of OR'ing a cluster.  But the error message that pops up is certainly ambiguous and deep from within LabVIEW.

[ThiCop]

This is indeed something special...

Nice find!

However, I still find an OR operator with one input a bit weird 🙂

[Yamaeda]

Using 2 inputs (expanding the compound) you'll only get a boolean out.

@ThiCop: That's the whole idea of "More Compact Operators"!

@Yamaeda: That was exactly what I was trying to "create": a simple operator that would convert an error cluster into its Boolean component. So I shrunk the operator and to my surprise (but again that may be the "expected" behavior ;-), the output reverted to an error cluster. Then bam!

[ThiCop]

And then  you didn't use the unbundle by name because it had to be more compact?

[mikeporter]

Except that a single-input OR gate is basically a synonym for a wire.

I did, precisely for this reason.

I couldn't agree more. Moreover I think the whole idea of a signature is annoying. Which is why I turned the option of displaying signatures off. As a matter of fact, even the idea of avatars irritates me. In particular those which try to be original and poke fun at... now I am getting in trouble!

I'm with you on that one! (cough cough hack hack)

I'm better some years than others...

back on topic

I agree that no user actions (short of type casting) should crash LV.
