How should we help with your issue when you don't provide any substantial information?

I guess you know we cannot edit/debug/run images in LabVIEW.

Please provide (real) code!

(I prefer code backsaved for LabVIEW 2019.)

Best regards,

Basic question, did you save the file? do you use source code control, and did you commit/push? is there a chance that something is overwriting?

I don't really understand what you mean with 'reference' and 'dropdown of the reference'.

But if you enter values in controls and want them to be there again the next time you open the VI you can make use of 'Make Current Values Default' from the 'Edit' menu and save the VI.

I guess he refers to the drop-down list that appears when you link a reference or a property node to a given control.

If my guess is correct, some controls belonging to the tab misteriously disappear.

Having blank elements ("blank spot") in the list is certainly unusual. Are they really blank = empty?

Your description is insufficient, ambiguous, and contradictory to even start troubleshooting.

 

  • How can you click a reference if you say in the subject that they are "all gone"?
  • If this is a monolithic VI, why would you even need references? None should be needed!
  • What are parameters?
  • What action is "drop down a reference"?
  • If the tab is exclusively controlled by code (i.e. not by the user), it should be an indicator.
  • What is the code architecture?

 

Please attach your VI. (If it is a newer version, do a "save for previous" (e.g. 2019) before attaching.) we cannot debug images.
