FP.Get Image not working on a subVI if it has a picture control

  1. Download the attached (7.0).
  2. Open and save BOTH VIs in your own version. This is important, because it looks like if the VI is recompiled its FP is loaded into memory and the bug is not apparent.
  3. Run the VI. The indicators in the subVI are not updated the first time you run the VI.

This happens in 8.6 as well and requires the subVI to have a picture control and to have its FP closed.

 

One workaround is to use the first call? primitive and call the Open FP method (with the state set to hidden) when the VI starts running.

Hey Tst,

 

Thank you for the feedback.

 

I tried the vi's you have attached here and it updated the first time I ran the Caller.vi.

I must be doing something different from you.

Did you follow step 2? This can only be seen if the subVI's FP is not loaded, so you have to save the VI in your own version before running this. The easiest way is to call File>>Save All or to close and save the VIs and then open them again.

Hey Tst,

 

The issue has been filed in a Corrective Action Report (CAR ID#126219).

I couldn't see the behavior initially, but now I do!!

 

Sorry for the delayed response.

 

Thank you for your feedback.
