Trying to attach a TransitionEffect without name or group specified

[toverux]

Bug Information

Version Number of Plugin: 2.1.0 Device Tested On: Android Version of Xamarin: 4.5.0.617

Steps to reproduce the Behavior

I attached the effect through Transition.Name on an element:

<views:CoverHeader sharedTransitions:Transition.Name="RoomPicture" />

In the second page, the exact same thing.

Pages are pushed onto a navigation page that derives from SharedTransitionNavigationPage.

Expected Behavior

Makes the transition.

Actual Behavior

No transition is made and there's this in the logs:

===== SAHARED: update property for Aterno.Views.CoverHeader:  - RoomPicture
... a bit later ...
Trying to attach a TransitionEffect without name or group specified. Nothing done

sorry for the delay :) This debug information was not in the right place and was behing executed everytime: Trying to attach a TransitionEffect without name or group specified. Nothing done

So ignore it (this is gone in the next release) :)

Is your element inside a Collection of items? What's inside the coverheader? It should work, maybe try to apply the effect in a base element (not a custom view) and see what happens.

Hi @GiampaoloGabba, no probem, thanks. I tried again and this time, found the obvious mistake I made the last time.

Like I said, I inherited SharedTransitionNavigationPage, I did not use it directly. Obviously, I had a custom renderer attached to my own custom navigation page, and that one was still inheriting from NavigationPageRenderer ; the only thing I missed the last time was replacing this renderer with SharedTransitionNavigationPageRenderer.

Very sorry to have bothered you with that!
