Issue Details

I'm using the 2018 version of the Functional Safety Editor, and I've found that I am unable to add a transition condition to new state transitions. I am able to wire a transition between two states. However, when I click on the transition priority label or the transition wire, and try to edit the transition condition in the right toolbar, the text does not stay. After I click away from the dialog, it returns to its empty state. Why does this happen, and how can I work around it?


This is a known issue and has been reported to National Instruments. It has a Corrective Action Request (CAR) filed under reference number 726500. Additionally, you can avoid this issue by right-clicking on the transition wire and choosing the option "create transition condition." This will create a transition condition in the state diagram which you can edit. With this method, any added text will remain intact.
