Fabulous: Nullreferenceexception on MacOS changing Page

[SergejDK]

There is a problem with e.g. the AllControls sample on mac.
When you click on "MainPage" button it will crash.

This issue is from XF itself so we do not really need to change a thing at our side.

Here to track: https://github.com/xamarin/Xamarin.Forms/issues/4156

This issue seems to be resolved. In the next Version of XF this issue should be gone!
I don't know which version it is but I think 3.5 or 4.0.

[TimLariviere]

That's good to know :+1:
Seems to be planned for 3.5

[SergejDK]

Seems like XF 3.5 is out.
So when we update in the next time this problem should be gone.

Simple update of Xamarin.Forms to 4.5.0 does not solve this issue for me
I hope that it will gone with fresh update of Fabulous

My repro is here - https://github.com/sergey-tihon/Fabulous.BugRepros/tree/master/LayoutChange

[SergejDK]

The update will maybe not enough. Just saw an issue in XF where the issue still appears...

With 3.6 it seems to work on my mac.
@sergey-tihon I tested your reproduction with the update and it works now.

@TimLariviere So we can close this?

[SergejDK]

Tests are fine so can be closed here.
