Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

See Section 2.1.3 of the Application Developers' Guide. You may also find section 2.14 of the Toolkit Developers' Guid useful.
The code you have was written for Geant4 9.x. ActionInitialization was introduced with Geant4 10.0 in order to support multithreaded applications: each child thread needs its own set of actions, which is handled by having the RunManager call ActionInitialization in each thread.
If you force your application to be single threaded (e.g., by using G4RunManager unconditionally, with no option to use G4MTRunManager), then you can keep it the way it is. If you want to be able to run both single and multithreaded, then you should migrate to ActionInitialization, as described in Section 2.1.3 of the Application Developers' Guide.
