Error when docking

[tgjones]

This is caused by my workaround for this issue:
https://wpftoolkit.codeplex.com/workitem/20833

The original issue is that AvalonDock cleans up ("garbage collects", in its parlance) LayoutPanel objects with no children. That's a problem because I want to setup default LayoutPanel objects in ShellView.xaml, and then add tools to them at runtime.

My workaround is to add hidden "dummy" tools to the left, right, bottom sides, to prevent AvalonDock's garbage collection from happening.

However, that workaround causes the issue above - I haven't quite figured out why, but I think it's to do with only having a single hidden tool in a panel that you're trying to drop a new tool into.

It's not worth investigating too deeply, because it would be much better if the original issue is fixed. I'll track the CodePlex issue, hopefully it will be fixed soon.

Hi Tim, any news on this one?

[tgjones]

@Camuvingian Only news is that the AvalonDock bug is apparently fixed in 2.6. But thanks to the odd release schedule for Extended WPF Toolkit, that version won't be released to non-commercial customers until 2.7 or 2.8 has been released to commercial customers. See my comments in the work item, linked above, for my opinion on that :)

+1 to the best Extended WPF Toolkit weirdness. Once upon a time I took a hard look at them and figured they had one too many issues lagging yo make it worthwhile. I thought you were using CaliburnMicro? Or does CM use ExWPFTk?

@mwpowellhtx When Xceed acquired AvalonDock, they merged it (well, included it) with their existing Extended WPF Toolkit. So AvalonDock releases are now tied to the Extended WPF Toolkit release schedule.

@tgjones yes I understand that.
