Description
Problem is in cache of Component visibility introduced in WICKET-6839.
RFLAG_VISIBLE_IN_HIERARCHY_SET
If we use setVisibilityAllowed instead of setVisible exception is thrown.
org.apache.wicket.WicketRuntimeException: The component(s) below failed to render. Possible reasons could be that:
1) you have added a component in code but forgot to reference it in the markup (thus the component will never be rendered),
2) if your components were added in a parent container then make sure the markup for the child container includes them in <wicket:extend>.
One posible solution is to call cleaning visibility cache in method Component.setVisibilityAllowed.
e.g.
Method Component.setVisibilityAllowed should call onVisibleStateChanged() as method Component.setVisible does.
All is demonstrated in github project
