Answer 1

Two years ago I was confused by the same behavior, so I researched the problem to come eventually to the conclusion that everything had been fine and in accordance to the documentation.
In brief, it is correct behavior a button to submit the whole page even if the button is configured as partialSubmit="true". Please, refer to these articles in the documentation for clarification:
Using the JSF Lifecycle with ADF Faces - 11g Release 1 (11.1.1.7.0) ("4.3 Using the Opimized Lifecycle")
Handling Events - 11g Release 1 (11.1.1.7.0) (See topic "5.1.1 Events and PPR" only)
It is seen from the second article that command components (e.g. a command button, event type "action") are not event roots, which means that the whole enclosing page "boundary" is submitted. If the button is a part of a subform (<af:subform>), a region, a popup or a PanelCollection, then the boundary is the corresponding subform, region, popup or PanelCollection, so only this part of the page is submitted and processed by the optimized lifecycle. However, if the button is not part of such component, then the whole page is submitted and processed by the lifecycle (even if the button is configured as partialSubmit="true"), but only the partial targets of the button will be refreshed on the screen (if the button is configured as partialSubmit="true").
If you want your button to submit only a part of the page, then the easiest correct way to do that is to surround that part with <af:subform>.

P.S. Input and selection components have different PPR behavior from command components. It is seen from the second article above that all the input and selection components are event roots (in contrast to command components!) (see event type "valueChange"), so if some input or selection component is configured as autoSubmit="true", it will not submit the whole page but only itself and the components configured as partial targets of it.
