Asynchronous Front Panel Not Updating When Opened With Values

Issue Details

I am calling a front panel VI asynchronously and am populating the controls and indicators before I open the visible front panel.  On the first run, the controls and indicators do not populate. 


When a front panel is called, the panel will only change the controls and indicator values after it is open.  Any values written to the front panel before you open the object will not be shown once the front panel opens. You can update the value in the front panel after it opens by writing the data directly or using a property node to force the value change.
