After closing all documents, new document won't open

[BAndysc]

After all documents are closed, new documents won't show up, despite being added to the Dock model.

Please note this is not a bug in the sample, I have the same issue in my app.

Hey,

I agree that this is a bug, as a workaround you can create a custom DocumentDock and override IsEmpty and set it to false.

using Avalonia;
using Dock.Model.Mvvm.Controls;

namespace App.ViewModels;

public class CustomDocumentDock : DocumentDock
{
    // Fixes bug where the view disappears when empty
    public new bool IsEmpty => false;
}

That's why I love open source :) I couldn't find the root cause before, but after you posted your workaround, it become obvious that something is wrong with updating IsEmpty attached property. And I was able to make a fix: #322

Cool! I was just coming here to ask this exact question!

Your solution is working nicely!
But I have got another question, which seems kinda buggy in the case, when all documents have been closed.
What I really would like is that an empty FilesDocumentDock is not vanishing, when it has no children anymore, but that there is an option that it is staying there, just without any elements.

@TobiArndt You are right, there was IsCollapsable property, but it wasn't respected. Changed the PR to take that into account and now the document dock shall not disappear provided you set IsCollapsable to false

I wanted to start to fix this problem and started reading the code and getting all its logic, and you just did it. Was reading your changes in your pr. Quiet amazing and skillfull! Works like a charme!
