> I think isVisible should not be called after detach to prevent model reloads.
> I found one call to isVisible after detach in method
> ComponentRequestTarget#respond(RequestCycle). That method initiates a detach
> and then calls page.endComponentRender. This leads to a call to
> Page#checkRendering which calls isVisibleInHierarchy() and from there
> isVisible(). Method checkRendering only does something when the debug setting
> 'componentUseCheck' is enabled (which according to the javadoc is true by
> default).
> Short term workaround: set debug setting 'componentUseCheck' to false.
