Class probing Erratic Behavior in LV2019

Recommended Posts

I'm noticing that when I probe LV class wires in LabVIEW 2019 SP1, it won't display any data on the probe. In fact it appears as if that part of the code never executed. I just can't figure out how to reproduce it. I'm wondering if anyone else has noticed this behavior. I can clearly see that I have multiple probes on one diagram and the probe attached to a class wired shows "Not Executed" in the probe watch window, even though "Retain Wire Values" is enabled. LabVIEW restart does not fix it.

Ok this is so random how I found this, but I was able to reproduce it. I'm hoping others on here can reproduce it as well. If this is a known issue then please link to the source for reference. I've attached code that reproduces it.

But basically in order to reproduce it:

  1. Place a Map datatype in the private class data of the class.
  2. Make the Map datatype a typedef.

The behavior AQ mentioned is similar, but not quite the same.

In the LabVIEW 2019 f2 patch, we addressed Bug 188376 (CAR 742093).  That Bug resulted in a crash when probing class wires that included maps in the object's data.

I've reproduced the behavior you're seeing in LabVIEW 2019 SP1.  I filed Bug 966521 to get that on our radar.  As a quick note, I did test LabVIEW 2019 and the behavior isn't there.  If you need to debug, you can do so on a patched 2019 installation.
