FastCell: Cells not getting assigned the correct binding context. #1

The modifications I made to the sample project:

I added an index parameter to the MediaItem: public MediaItem (int index, ..., ..., ..)
In the DataProvider class' GetMediaItems() method, I pass in the index value for each media item.
Add a label in the ComplexFastCell XAML layout with an x:Name property of "IndexLabel"
Set the Text value for the IndexLabel to the index of the Media Item.

After scrolling up or down a few times, you can notice the index numbers displayed on the label are inconsistent.

I've resolved this on iOS. I'll push up the fix now.

The problem didn't exist on android. So you should be good. Note, to expediate the fix for you, while doing other stuff, I've not tested for leaks. (in fact, I've not tested for memory leaks at all with this yet).

so please be warned! Saying that - I appreciate you trying it out and raising the issues. If you find any other problems which will prevent you using this, I'll be sure to resolve them quickly. We use this mechanism for our own projects, so we are heavily invested in it.

I'll likely re-open this.

Xamarin forms 1.4.3 totally hoses debugging in many of my projects. I think I'll just make it use 1.4.3 on the android project and hope for the best. Extremely frustrating bug.
