NI.StatechartInstantiateVI has unsaved changes (LabVIEW 2012)

[JKSH]

I was editing a statechart transition, and clicked "OK". LabVIEW gave me this dialog:

If I click "Save - All", LabVIEW asks me to specify a location to store the VI. What's going on? I thought Statechart VIs are managed internally, and cannot me accessed by the programmer.

Anyway, I clicked "Don't Save - All". The edits I made to the transition seem to have been preserved though.

Has my statechart become corrupted?

When you create a new, simple statechart (new project) and edit transitions does the message occur, or do you only get the message for your current project?

Also are NI.StatechartInstantiateVI 60 &70 your user defined names of the VI's in your project or are these names foreign to you?

Hi Eric,

I only saw that message for one specific statechart in my project. Other statecharts in my project are fine; new statecharts are fine too.

However, if I try to rename that statechart, I will be asked to save changes to other VIs in my project, and I will eventually get a lot of messages in this form:

• Cannot load Help Information of "Pump_Variable.lvsc:Guard.vit".
• Cannot load Help Information of "Pump_Variable.lvsc:Action.vit".
• Cannot load Help Information of "Pump_Variable.lvsc:Trigger.ctl".
• etc. etc. etc.

The names NI.StatechartInstantiateVI 60 &70 are foreign to me; the name style does not match anything remotely similar in my project

Hello,

I'm not finding documentation regarding this issue, so if you could post your code such that we could attempt to replicate the error that would be great.

Thank you,

Eric
