This class control (or constant) is permanently broken

[pawhan11]

Hello,

Cross post from NI forums. I have more than 200VIs having the same problem.

 

I have tried to replace by scripting or quick drop but no success.  Delete and require is hard to do from scripting top maintain connection pane and others form what i ve seen so far. Have You ever seen this error? I do not recall doing some extraordinary class manipulations when this error happened

No, this is the first time. However, I used the LabVIEW Resource Editor to look at the default data of those controls and they expect the class library inside a project library ("BBP Database Processor.lvlib").

<DefaultData>"%00%00%00%011%1CBBP Database Processor.lvlib%12Operations.lvclass%00%00%00%00%00%00%00%00%00%00%00"</DefaultData>

You probably moved the class out of the library without saving its members (not sure about the exact steps, actually). You should revert your code to the last known good state. Hopefully you have version control in place. Alternatively you could try moving the class library back inside the project library. That might fix the VIs.
