**Ignition 8.0.16-RC1 - Perspective**

I use a view canvas with an array of instances (multiples viewsPath)

When I open a view with the canvas, events **onStartup** (on root) are triggered for each instance.  
If I close the view which contain the view Canvas events **onShutdown** are triggered for each instance.

If I I open a view with the canvas, events **onStartup** (on root) are triggered for each instance.  
If I write the array of instances of the view canvas with the script, on one events **onStartup** and events **onShutdown** are triggered. Not alaways for the same instance view.
