Avalondock: MVVM can't show hidden LayoutAnchorable after Deserialization

[Masc]

#48146 |

Hello,

I encountered a bug, that hidden LayoutAnchorables cannot be shown when loaded from an XML (Deserialization).

The problem is a little bit hard to describe, but i try my best.

The first problem (bug) i had, was when i added LayoutAnchorables to my ViewModel. They appeared as intended but there was a blank space on the left. I managed to build a workaround:
– there was an empty LayoutDocumentPaneGroup created by the DockingManager (is that intended to happen?)
– if i remove this LayoutDocumentpaneGroup everything works just fine

The 2nd problem needs a little bit more explanation:
– In my Test-Application i add 3 LayoutAnchorables, they are organized in Tabs:
| 3 | ( || are the borders and 3 means 3 tabs)
– after that i do the following steps:
1. | 2 | 1 | (move one LayoutAnchorable to the right)
2.
| 1 | 1 |
---------
| 1 | (move one LayoutAnchorable to the bottom)
3. Close the application (it gets serialized)
4. Open the application (it gets deserialized, the layout gets loaded)
5. Hide the upper 2 LayoutAnchorables => that leaves a blank space (why?)

---------
| 1 |
6. Close the application and reopen it
7. The Layout that gets loaded is:
| 1 | (no blank space)
8. I try to make the other LayoutAnchorables appear by setting the bound Property IsVisible to true => they dont appear

I could recreate this behavior in a small Test-Application, where i removed every unnecessary part. I could also send you a little video of the bug, because its hard to describe.

Thank you in advance.
