I think the error is hitting the line below in the LTRTheme.xaml It seems like such error should will popup on other attached properties like Height too. Right now, it is throwing that error only on the first occurrence.

    <Rectangle x:Key="MainMenuItemTemplateNewBadgeLayoutBounds"
               Width="{x:Static AbsoluteLayout.AutoSize}"
               Height="22"
               X="1"
               Y="0.5" />

Could this be similar (not same) to #694 ?

Hi @IoTFier That "rectangle code" is not in the original code of LTRTheme.xaml or RTLTheme.xaml I think it is not related to Grial

Hi @fcastro07 , please don't close issues until I get to respond to your question raised in the conversation. Even, I have no interest in keeping tickets open. But, logically you should allow me to close the ticket once the issue is addressed.

Please open this ticket as I can't reopen it being not a owner / contributor on this repo.

I would appreciate that courtesy.

Thank you, Nilesh

Nilesh. Sorry for the inconvenience. Feel free to ask whatever you want.

Hi @fcastro07 , thank you for your consideration.

In the migration of my App from Grial 2 to Grial 3 (3.0.68-RC now), I migrated one of the AbsoluteLayout.LayoutBounds

<Setter Property="AbsoluteLayout.LayoutBounds" Value="1,0.5,AutoSize,22" /> to <Rectangle x:Key="TemplateLayoutBounds" HeightRequest="22" WidthRequest="{x:Static AbsoluteLayout.AutoSize}" X="1" Y="0.5" /> in LTRTheme.xaml and similary in RTLTheme.xaml

Apparently, this is breaking since XF 4.7 pre-4 and now in XF 4.7 GA as well.

Changing Height and Width to HeightRequest and WidthRequest resolved one problem, but X and Y - attached properties of ViewElement are made as readonly. So, now, I am facing error System.InvalidOperationException: 'The BindableProperty "X" is readonly.'

Any clue ?

Have you Grial 3.0.68-RC compiled against XF 4.7 ? I want to use Shapes API and new Grid API changes.

Your help will be appreciated.

Thank you

Hi @dirivero , @fcastro07 ,

Will you please help me with my request above?

It is the UXDivers.Effects that's failing ...

Is there a new update with the Grial Sample app in conjunction with XF 4.7 ?

Thank you,
