Say I have a component Foo that defines an action link on a zone
rendered by component Bar.
Components are supposed to be self-contained, so having one component
updating a zone inside another one is not recommended at all.
I receive an error noting that Foo does not define a component Bar.
My understanding is that neither components Foo nor Bar have any
knowledge of components rendered within one another (the attribute t:id)
is not global.
Correct. A t:id is local to the template at which it's declared.
I therefore infer that
component communication occurs only when they coincide within the same
immediate container and one component is child to the other. Is this
correct?
No. I can see these kinds of communication in Tapestry:
* Events (inner to outer)
* Parameters (outer to inner)
* Environment (outer to inner and inner to outer)
