Removing a child from a "Panel" gives ClassCastException

Hello,

I have a structure where I'm using a Panel and a child component:


MyVerticalLayoutComponent
    |__MyPanel
        |__MyCustomReferencedComponent

I want to replace "MyCustomReferencedComponent" with another referenced component, e.g. MyCustomReferencedComponent2.

So, I drag the new component onto MyPanel and I get the following result which is good:

MyVerticalLayoutComponent

    |__MyPanel

        |__MyCustomReferencedComponent
        |__MyCustomReferencedComponent2

Now, if I right-click on "MyCustomReferencedComponent" and select "delete", I get the following exception:


java.lang.ClassCastException: com.vaadin.ui.Panel cannot be cast to com.vaadin.ui.ComponentContainer

at com.vd.ui.DesignerUI$2.remove(DesignerUI.java:359)

I thing that the deletion from a Panel component has this issue in general.

Any ideas?

Cheers
