Fix issues #22 and #25 (duplicates)

[sdarveau]

Use an ObservableCollection instead of custom BindableObjectCollection. Since we need to specify a template parameter, VS is enable to resolve it correctly.

• update version number to 1.4.1

Thank you very much sdarveau, your fix is very useful and working perfectly for a long time. It looks like davidbritch is very busy and doesn't have time to check new issues, so we have no choice but to solve them on our own.

I recently updated VS 2019 to version 16.7.1 (because of apple account login issues, now it works) and got the following xaml error:

A value of type 'InvokeCommandAction' cannot be added to a collection or dictionary of type 'ObservableCollection`1'.

Everything is compiling and working just fine with your fix, but this new xaml error is annoying. I am quite new to Xamarin and currently don't know how to fix this by myself. Can you give me some advice? Or just point me in the right direction, how I can solve this issue. Thanks.

Hi @gresolio, I'm working on VS for mac (version 8.7.3) so I can't relate. Have you imported the Behaviors project into your solution so you can modify the code and see the effect instantly? Don't forget to add a reference to this project.

[gresolio]

Yes, I'm using Behaviours source files in my solution, with your fix on top ActionCollection => ObservableCollection<IAction>, not a NuGet package.

Strangely enough, after "Build/Clean Solution" and manually deleting all temporary project files, this xml syntax error disappears for a while, but then appears again.

Functionally nothing broke, the project compiles and works as before, it's just an annoying syntax error in the xaml editor.

Thanks for the answer. Hopefully, I will find some solution.

Yeah this will solve the problem.

Thanks @BOBx5, it looks like returnType: typeof(ObservableCollection<IAction>) does the trick :)

But I took a different path and completely got rid of the XAML: I gradually rewrote the entire UI to C# Markup.
Only positive impressions, I can recommend it 👍
