We use RadDock & RadBusyIndicator extensively throughout our product and have run into an issue where the RadBusyIndicator is disappearing or isn't respecting IsBusy when true. If the PersistenceManager is used to set the layout of the RadDock which contains a RadBusyIndicator, after which the indicator can no longer be set to IsBusy through bindings. It can however be set directly on the property. It's as if the binding is unhooked or as if the data context is lost, even though debugging show they seem to be still wired up.
How can we address this issue?
PS I opened a support ticket as well.
