LV2012 crashes when opening LV2010 project containing OOP and dynamic FPGA references

[Chris_12345]

I have a project that was written under LV2010 and has no problems that I am aware of. This project contains OOP and dynamic FPGA references. I am trying to upgrade this project to LV2012. When opening this project under LV2012 (or any subVI containing OOP) I get an error message, as shown in the attached screenshot. Has anyone else observed this problem? I haven't found any relevant postings on this forum yet.

My project is quite large, with many accessors.

Thank you for any assistance you can offer.

Hi Chris,

I was able to find a discussion forum thread where someone had a similar error. Apparently it was due to trying to close the same reference more than once.

If that does not resolve the issue, I would try to open a different LabVIEW 2010 project in 2012 and see if you get the same error.

Thank you for your response, but the Discussion Forums link that you provided refers to a problem that occurs when exiting a running executable. My problem is different. I am simply opening up a LV2010 project using LV2012. No running of my program is involved.

Anyway, after several days of work, I narrowed down the cause of the LabVIEW crash. My code contained a Disable structure, and within that Disable structure there was a subVI that had an unwired object terminal (set to dynamic dispatch). Deleting the subVI in the Disable structure eliminated the LabVIEW crashing. Weird behavior.
