Jki State Machine Explorer cannot be started




My design with JKI-sm has evolved into a state where I can no more start the "Jki State Machine Explorer" (JSME) on the project.

I assume it is because I have added som changes to the architecture which prevents JSEE to recognize the JKI-sm structure - but I cannot figure out which.

It works nicely on a fresh (and empty) design so it is not an installation issue and it has started to appear during the development phase.

I use JKIsm version announcing it as 2018 on the while loop rim, (vipm says version 0.7.45), LV2019/64bit but LV2020/64bit behaves the same.

What I see is that

  1. Right-click on the rim of while loop, case structure or event structure does not show the JSME menu item.
  2. Only right-click on the state string enables the JSME menu item for selection but the JSME does not appear, and no errors are shown - just silent

Hope to get suggestion on how to fix this as the Jki State Machine, primarily because of the Jki State Machine Explorer, are very useful tools!

Ok, It was not that hard to backtrack what created the malfunction of JSME:

Adding a case structure after the SM case as shown in attached snippet breaks the JSME. The intended purpose is to take a snapshop of the state queue when an error is detected. I will find another way to do this kind of logging which is compatible with JSME. Suggestions are invited.

I am curious as to what are actually the requirements for proper function of JSME.

Again on the logging side - I have made a small vi which will record the history of the states. Uses a queue and functional global for ease of use. As here 977692445_JSMEinbrokenstateandwithlogger.thumb.png.ca43ac72ce561afeb3410593bd52eabb.pngplaced on the diagram it does not break the JSME.

Maybe it is useful to others.
