As explained in the previous section, CAE ViewHookEventListeners
are used to make data to be tracked (and the tracking configuration itself) accessible when rendering a view. This
data is used in views to build the tracking calls.
CAE ViewHookEventListeners react on rendering of
com.coremedia.blueprint.common.contentbeans.Page beans to add code into the head of a
page. The analytics integration uses the head view that serves
the following purposes:
headIncludes third-party tracking libraries,
Sets up vendor-specific JavaScript data structures required for tracking and
Includes the asynchronous calls to the JavaScript tracking code.
GoogleAnalytics.head.ftl
includes JavaScript libraries specific for an external service and converts the tracking data
into JavaScript objects used by the final tracking calls. The FTL checks if the service provider that it implements is enabled for
the current page, that is, if it is properly configured and not explicitly disabled.
Page view tracking calls use the property "enabled " to check whether the third-party service is enabled. Setting this property
explicitly to "false", disables the service provider, while setting it to "true" will only enable further
processing of the provider's configuration (which might ultimately enable that service if the configuration is
complete).
