ArgumentNullException occurred related to NodeList.
rasimcekic opened this issue · 2 comments
Thank you for sharing this library.
I use AvalonDock and your library in my project. When the program is first opened, everything works normally like this.
When switching from dock mode to float mode, I am encountering the error. "An unhandled exception of type System.ArgumentNullException occurred in System.Reactive.dll Value cannot be null."
The code below works when switching to float mode.
`
public NodesListView()
{
InitializeComponent();
ViewModel = new ViewModel();
//DataContext = ViewModel;
this.WhenActivated(d =>
{
this.OneWayBind(ViewModel, vm => vm.ListViewModel, v => v.nodeList.ViewModel).DisposeWith(d);
});
}
}
`
1-When I comment this.WhenActiveted part, I do not encounter any errors.
2-When I switch Nodelist from tiles to list mode and then switch to avalondock's float mode, I don't have any problems As seen in the picture below.(this.WhenActiveted part is not comment line)
The detail of the error I encountered is below.
-

What can i do to fix it?
This appears to be related to an issue I posted, #77. In my case, it's related to nodes having multiple controls on them.
Thanks for your bug report. Is this still reproducible in the latest version? If so, could you provide a minimal reproducible example? (preferably a zip file with a project that I can debug)
