When we save a menu item a second set of component parameters are saved to the
menu item. This means that the component parameters are saved as part of the menu
item, not the component. The idea is that it allows a component, which can only be
installed once, to be linked to from the menu multiple times using different settings.
This raises the question: What is the purpose of the component preferences button in
the backend? The preferences button, used to save the component settings, is used to
modify the default component settings.
The default settings are used when we create a new menu item as the initial
'Component Parameters' values. They are also used if the component is invoked but
the active menu item does not correspond to the invoked component.
Imagine the link index.php?option=com_foobar. This link will invoke the com_
foobar component, but because no menu item is specified the active menu item will
be the first menu item in the main menu.
Now imagine the link index.php?Itemid=53&option=com_foobar.
