XamarinCommunityToolkit: CameraView issue - EventToCommandBehavior: Couldn't resolve the event
Hello there, I’m using CameraView and EventToCommandBehavior to create some sort of a simple app that makes photos. But I’ve faced with the issue of using EventToCommandBehavior. When running app in Release mode on both android emulator and real device I do see the following error in Application Output:
[MonoDroid] UNHANDLED EXCEPTION: [MonoDroid] Android.Runtime.JavaProxyThrowable: Exception of type ‘Android.Runtime.JavaProxyThrowable’ was thrown. [MonoDroid] — End of managed Android.Runtime.JavaProxyThrowable stack trace — [MonoDroid] android.runtime.JavaProxyThrowable: System.ArgumentException: EventToCommandBehavior: Couldn’t resolve the event. [MonoDroid] Parameter name: EventName
The code itself isn’t that complicated:
<xct:CameraView
x:Name="CameraView"
BindingContext="{Binding CameraModel}"
CameraOptions="{Binding CameraOption}"
HorizontalOptions="FillAndExpand"
VerticalOptions="FillAndExpand"
CaptureMode="Photo">
<xct:CameraView.Behaviors>
<xct:EventToCommandBehavior EventName="MediaCaptured" Command="{Binding CaptureCommand}" />
</xct:CameraView.Behaviors>
</xct:CameraView>
The Environment is the latest one at this moment:

Hi @workgroupengineering 1.3.0-pre2 was just released, please have a look 👍
Hi @workgroupengineering as I thought, 1.3.0-pre1 doesn’t have the fix, it’s merged into dev branch only.
Hi @workgroupengineering, what is the event that you are using? It would be great if you could add more info 👍 one more thing, I will need to double check, but I think the fix is not released yet.
@GUOLDEV I didn’t test either, for now, I’ll assume that issue is general
@pictos do you mean the sample code? If so, you can find it here.
