NullReferenceException when adding template "Display Gauge" to Composite Action

[pre-martin]

Add a Composite Action to a button or a dial, select "Elements" in the tree and add "Display Gauge" as template.

Expected behavior: Action filled with Gauge elements.

Actual behavior: The Action Designer crashes with a NullReferenceException. See below for stack trace.

Reason: ModelDisplayElement.AddManipulator() calls ElementManipulator.CreateInstance(type, null, null). ElementManipulator.CreateInstance() accesses this third parameter (which is null):

Version: 0.8.0

Stack trace:

Good catch!

Try the Dev Build, should be fixed: https://github.com/Fragtality/PilotsDeck/blob/master/Install-PilotsDeck-latest.exe
