Summary0003994: Difference EventTriggerBaseT.GetSource between WPF and Noesis
Description

While implementing a custom event trigger, I noticed a difference between Noesis and Wpf implementation of GetSource(C++)/Source(C#)

Context: The trigger source has not been on the xaml ( see reference )
Trying to fetch Source during OnAttached method produces the following
[WPF/C#] Source, returns the associated object ( Since source is not assigned )
[Noesis] GetSource, returns null

Attached a reference screenshot on a breakpoint showing the values of both getsource and getassociated object

Steps To Reproduce

1- Implement a dummy CustomEventTrigger inheriting from EventTriggerBaseT<FrameworkElement>
2- Override OnAttached event
3- Use the custom event trigger in xaml
4- Use GetSource inside OnAttched event
5- Place a breakpoint after assigning it to a variable
6- Launch the application
7- The the application to hit the breakpoint

Expected: Both behave the same way
Actual:
[WPF/C#] Source, returns the associated object ( Since source is not assigned )
[Noesis] GetSource, returns null

You can close this ticket, I have confirmed it was an implementation mistake within OnAttached method
I was not calling the base implementation before running the code, doing that solves the issue.
In c# i was not calling the base class and it was working fine, that made me not notice i was not calling the base implementation.

I still think we need to fix the GetSource() to calculate the source if it was not done before.
I'm leaving it open and will change that for the next release.
