Description

A page having a component from inherited markup and fragment with the same id fails with misleading exception message.

Exception message:
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> ... and list of component id's from fragment multiplied by amount of rows in DataTable

Cause: The markup of the component is used by the fragment.
