Method Component.setVisibilityAllowed should call onVisibleStateChanged()
as method Component.setVisible does.
Else 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>.
Step to reproduce:
- run test com.mycompany.TestHomePage.homepageRendersSuccessfully
- If you change wicket version to 9.1.0. Test will pass.
Problem is in this method

where determineVisibility() != getRequestFlag(RFLAG_VISIBLE_IN_HIERARCHY_VALUE)
