Anyone seen error 1508

Hey Taggart,

Thanks for the post. So as I understand it, you have error 1508 when trying to save, correct? And this is still occurring right? Are you able to post a simple reproducible case?

Thanks,

I will see what I can do about making a simple reproducible example. 

Basically:

It's a scripting program.  The program starts by copying a template library and that seems to work fine.  Then inside the new library there is a class (an actor actually) and the scripting tool takes one of it's methods and creates a new copy of it (.vi or .vit here does not seem to matter) and then modifies it and goes on to use the AF project provider to create a message.  Then I save all on the library (and I even added saveall on the entire project.)

And it repeats this several times.

The problem is that the first time through, the scripting executes fine.  The second time through when I go to copy the "template" method, I get error 1508.  If I breakpoint right before then and click on save all this project (or on the library) labview appears to save some stuff - but the dialog disappears so fast I can't read what it is saving.  However that still doesn't help.  I still get the same error.

I am doing a save all on the library (and I added a save all on the entire project) at the end of each loop iteration, so I am not sure what the problem is...  I tried a whole bunch of stuff, like throwing a bunch of save all this project, and save all this library in random places and none of it seemed to help.

Nevermind.  I figured it all out. Had to do with application instances.  I was accidentally opening something in the wrong application instance and it was locking the class.  That was why I was getting the 1508 error.  Changing the app instance fixed that.

thanks for all your help.
