AvaloniaEdit 11.0.0 - Mac OSX bug - after editing text

[alexandrehtrb]

My TextEditor`s Document is binded with the ViewModel like this:

[Reactive]
    public TextDocument? RequestRawContentTextDocument { get; set; }

    public string? RequestRawContent
    {
        get => RequestRawContentTextDocument?.Text;
        set => RequestRawContentTextDocument = new(value ?? string.Empty);
    }

The TextEditor has the following text, that I edit by backspacing and reinserting the }}, characters:

{
  "id": {{MyIdSecret}},
  "nome": "Alexandre"
}

When accessing the property, the app crashes

Bug detected only on Mac OSX, does not happen on Windows nor Linux

@Gillibald It seems something related to the IME.

[Gillibald]

Y there is a null check missing when focus gets lost

[chenjing1294]

Command+F also causes this error

[danipen]

@Gillibald are you planning taking a look into this one?

I was experiencing the same issue, which was fixed with https://github.com/AvaloniaUI/AvaloniaEdit/commit/1a2a644661957d38e1d14f48d58e726a7aa29d9f (validated the fix by running a variant of the package based on the master branch).

Not sure when a 11.0.1 version is planned to be released?

@Takoooooo is possible you to build a new nuget?

@danipen Done https://github.com/AvaloniaUI/AvaloniaEdit/releases/tag/11.0.1
