Indicators don't get updated on the FP but looks ok on the probe

[nanocyte]

I'm trying to show the path I created but it doesn't show up until I hit stop. To prove that my path isn't empty I added a length indicator and I can probe that wire and it looks fine but that indicator doesn't show up either

funny ... it has something to do with the feedback node. Also the diagram disable structure seems to be involved.

Looks like that some kind of optimization caused the issue. Remove the feedback node or remove the wire from the feedback node to the diagram disable structure or user a property node instead of the path terminal ... (there are several other possible solutions, but not everything is working).

I agree that this is a bug, probably caused by some compiler optimization.

I can fully reproduce it even in LabVIEW 2022 Q3 and have posted a note in the 2023 annual bug thread.

It was definitely a headscratcher for me.  I couldn't come up with something even remotely reasonable as an explanation.

Here's a smaller (😟) example:

Execution highlighting doesn't fix this, making me think the compiled code is off.

I guess I have to wrap all feedback nodes I ever used (well, in UIs):
