I have seemingly found an issue with the shipping example code for Nested Malleable VIs. Another user has verified that he saw the same behavior in 2019. I am working through the examples and the presentation from NIWeek 2019. In running the Lesson 2b code (C:\Program Files (x86)\National Instruments\LabVIEW 2019\examples\Malleable VIs\Nested Malleable VIs) I found the Equals.vi in the class was not being leveraged and the search failed. When I went to my LabVIEW 2018 machine and ran the Lesson 2b.vi the code worked to find the element by correctly leveraging the in-class Equals.vi. One difference I see is that in the 2018 example the Equal.vi is in the example folder with the code, and in 2019 the Equal.vi has been moved to VI.lib - otherwise the code looks to be the same. The Equals.vi code looks identical, and the calling VIM look identical. I posted on the LabVIEW NI.com forum here: https://forums.ni.com/t5/LabVIEW/LabVIEW-2019-Malleable-VIs-Shipping-Examples-Lesson-2b-Nested/m-p/3966044/highlight/false#M1129678 I am trying to determine what may have broken or changed between the implementation in 2018 and 2019, visually the code looks the same.
