Incorrect Boolean Control When Button and Asynchronous Call Are in the Same Event Structure?

Issue Details

Opening a VI reference and making an asynchronous call inside a while loop containing an event structure (as shown in the picture below) causes a Boolean control with the Switch or Latch Until Released mechanical action to not wait until released. How can I fix this?
 

 

Solution

This is a known issue with LabVIEW which has been raised to the Development Team.

While the issue gets resolved, an alternative approach would be to open the VI reference outside the While Loop.

The VI snippet below shows the alternative code which allows you to obtain the desired Boolean Control Behaviour.
