Bug Information

Version Number of Plugin:1.5.0 Device Tested On: Simulator Tested On: Android Api 31 Version of VS:17.0.5 Version of Xamarin: 5.0

Steps to reproduce the Behavior

1. Create a Validtable Property to List. public Validatable<string> Value { get; set; }
2. Subscribe to the Property's On change event. Value.ValueChanged += Value_ValueChanged;

Expected Behaviour

When the value is changed, the ValueChanged event should be called once. However it is triggering twice.

Actual Behavior

The event is trigger twice.

Code snippet

Quick look leads me to believe the cause is here:

• Value's Setter fires the event and calls FormattedValue's Setter.
• FormattedValues's Setter also triggers the same event.

So the fix could be for the Value's Setter to update the FormattedValue's backing field or create another event for FormattedValueChanged
