Dynamic choice of bean in EL

Question

Is there a way to specify a managed bean used in EL at runtime and not design time? E.g. actionListener=\"#{myBean.method}\" such that myBean part

Answer 1

If your question refers to generating a set of pages for a number of subclasses with common elements you can also use page composition to achieve this.

For example if Resident and NonResident are managed beans for subclasses of Person:

eg. in 'non-resident.xhtml'

and in 'resident.xhtml'

then 'anyone.xhtml' can define the common elements using 'Controller' for the bean name.

This approach also enables you to eliminate duplicate page definition.
