Hi,

when dragging multiple toolwindows to the Workspace an Exception is thrown:

System.ArgumentException: The TabbedMdiHost cannot open the window 'Toolwindow 1' because it is already open elsewhere.

Reproducing the bug:

Create and run a MainWindow with the following xaml:

<Window
x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:docking="clr-namespace:ActiproSoftware.Windows.Controls.Docking;assembly=ActiproSoftware.Docking.Wpf351"
Title="MainWindow"
Height="350"
Width="525"
>
<docking:DockSite>
<docking:SplitContainer>
<docking:Workspace>
<docking:TabbedMdiHost />
</docking:Workspace>
<docking:ToolWindowContainer>
<docking:ToolWindow Title="Toolwindow 1">
</docking:ToolWindow>
<docking:ToolWindow Title="Toolwindow 2">
</docking:ToolWindow>
</docking:ToolWindowContainer>
</docking:SplitContainer>
</docking:DockSite>
</Window>


Try to dock the ToolWindows into the Workspace.
The exception only occurs when multiple ToolWindows are dragged.


Best regards,

Hi Christian,

Are you sure you are using the latest version? I believe this issue was fixed in the last release.

Indeed. I'm using Build 532 ..
i will try to reproduce with the newest service release.
The latest build of this product (v2019.1 build 0684) was released 10 days ago, which was after the last post in this thread.
