grayed out probe. "no debug info"

[billko]

Hi, Everyone:

I have a strange problem where I put a probe on a (double) wire and it is grayed out and says "no debug info".  When the data goes through the probe (in highlight execution mode you can see the dot go right through it - sometimes) it says "not executed".  This doesn't seem to be cosmetic, either.  It causes calculation errors downstream.  Does this sound like a corrupt VI?  It's not set to "re-entrant" and probes I put elsewhere seem to be "normal".  It's just that wire...

Edit:

I forgot, when we probed the same wire in another state, it contained error info???  (Wire still looked like a double.)

Is there anything else that is not default about that VI? Running in-lined or with special priority?

Have you tried clearing your compiled cache?

[altenbach]

Is that probe inside a parallel FOR loop?

(You cannot probe inside a parallel FOR loop unless you temporarily change the options for it, forcing sequential execution)

Hi, Everyone:

Sorry it took so long to get back to you all.  I should've remembered to clear the cache, that may have solved things.  SO anyway, we did the tried and true snippet to new VI and it worked.  (It appeared that all the previous versions had the same issue, but it could've been corrupt cache.)

Oh, well.  Since we have versioned it in GIT, I can just go one rev back, clear the cache, then see if that works.
