If the context needs to be shared, it needs to be exposed to the rest of the environment in some way. One option is for the page to implement an interface; components get get the page (from ComponentResources) and cast it to the interface to obtain the desired information.
Another option is a per-thread service that stores the data; the page injects the service and invokes the setter method(s), the components inject the service and invoke the getter method(s). A third option, used when rendering, it to collect the context information into an object stored into the Environment; components can use @Environmental injection (a special kind of per-thread data binding) to access the values.
