What kinds of things can be broken on a diagram?

[Darren]

I'm writing a VI Analyzer test that involves detecting items within a subdiagram (like a case of a case structure) that might be broken. So just checking if the VI is broken isn't granular enough, I want to know the broken things on a certain subdiagram. Here are the things I can think of that I could detect through scripting that would tell me a subdiagram is broken:

1. Broken wire

2. Broken subVI (including a bad subVI linkage)

3. Unwired required parameter on a function/subVI

Can y'all think of anything else?

Array constant undefined type

and a few more:

missing SubVI (probably falls into broken SubVI)

format string problems with "Format into String" node

missing type definitions / other type definition problems for constants.

Scratching my head a bit around bundle/unbundle.  I think most of these errors would be found through broken wire checks.

Thanks, Warren. I've added your suggestions to my test. Let me know if you (or anybody else reading this) can think of other broken items I can check for.
