Hello!
I have an issue with my XamComboEditor constantly resetting its items selection state. See the example project attached.
In my case I have a XamTabControl representing layers, which tabs are populated via TemplateSelector and can be of three types: A, Band C (each has own view and viewmodel). The latter two types can have links to other (target) layers, and utilize a multiple-choice XamComboEditor there.
The problem arises when I switch between different types of layers. For example:1. When you launch the example app, there is already one layer "A 1"2. Add two layers of type B (click +B button)3. Within each B-layer select any target layer via XamComboEditor:—When you switch between layers of the same type B, the selection of targets is persisted.—Whenever you switch between layers of different types (e.g. from A to B), the selection of targets is reset.
Hello Pavel,
I have investigated your issue, and I have asked our engineering staff to examine this further. To ensure that it will receive attention, I have logged this behavior in our internal tracking system with a Development ID of 228283. The next step will be for a developer to review my investigation and confirm my findings or to offer a fix, or other resolution.
Please let me know if you need more information.

The development team has reviewed the behavior with the SelectedItems not being preserved when selected tabs are changed and concluded that there are a couple of settings that leads to this state. One thing to note is that the SelectedItems binding is left with the default binding mode in the sample which is TwoWay, but the binding should be OneWay:
VerticalAlignment="Top" SelectedItems="{Binding Path=vm.SelectedRegions, Mode=OneWay}"...
static VM() { XamComboEditor.AllowMultipleSelectionProperty.OverrideMetadata(typeof(XamComboEditor), new FrameworkPropertyMetadata(true)); }
